Passenger Bus CDL Class B Pre-Trip Inspection

Pre-trip inspection passenger bus class b.

The commercial driver’s license (CDL) pre-trip inspection for a passenger bus includes 71 items to be checked.

You must name and point to or touch each item, and fully explain what you are inspecting (you must ensure the tester knows what you are referring to). You are getting graded that you know what to check each part for, not that you know the names of the parts. You will have to check each axle as outlined. There is no order or sequence to the test. If you miss a part, you can go back and identify it.

At the end of this checklist (scroll to the bottom of this page), you will find procedural videos to assist you in understanding the requirements for successfully completing the Class B (Passenger bus) Pre-Trip Inspection.

CDL Pre-Trip Inspection Checklist

Studying this Class-A CDL pre-trip inspection checklist is an important part of truck driver training. Before getting your Class-A CDL and finding an entry level truck driving job , most states will require students to pass a DOT (department of transportation) pre-trip inspection test and a general knowledge test .

Each company’s pre-trip inspection varies slightly. Most likely you will have to do the coupling system, light check and in-cab inspections plus one of the remaining three sections.

There are many sections to learn but the test is not as difficult as it may seem. Studying our simplified Class-A pre-trip inspection checklist and taking classes at your local CDL training school will get you prepared.

Engine Compartment

Driver door fuel area, coupling area, light check, in-cab inspection and brake tests, belt driven alternator, belt driven water pump, brake chamber, brake lining, caste nuts and cotter pins, coolant reservoir, gear box and hoses, gear driven air compressor, gear driven power steering pump.

  • General Hoses

Leaf Springs

Power steering fluid reservoir, shock absorber, slack adjuster and push rod, spring hanger, steering column, what to check for:.

When checking the engine compartment, you will always want to make sure the following components are properly mounted and secured. You should also make sure they are not cracked, bent or broken. The items you will need to check for include:

  • Make sure all of the wires are connected. The belt should not be cracked or frayed and the free play on the belt should be between ½ to ¾ of an inch.
  • The free play on the belt should be between ½ to ¾ of an inch. Also check all the hoses running to and from the water pump to make sure nothing is leaking.
  • The brake chamber should not be leaking air.
  • The brake drum should be properly mounted and secure.
  • The brake hose is rubber, so it is important to make sure it is not leaking air.
  • Check for oil or debris on the lining. There should be at least ¼ of an inch of friction material.
  • Make sure all three caste nuts and cotter pins are present.
  • The reservoir should not leaking and must be filled to the manufacturer’s specifications.
  • Make sure the drag link is properly mounted and secure, and not cracked, bent or broken.
  • The gear box and hoses should have no abrasions, bulges or cuts, and should not be leaking.
  • Although the air compressor is hard to see, you must make sure it is properly mounted and does not leak.
  • The steering pump is located in the same place as the air compressor and is also gear driven. Ensure the steering pump is not leaking.

General Hoses (Passenger and Driver’s Side)

  • The hoses should be secure at both ends. There should be no abrasions, bulges or cuts. Fluids run through these hoses, so it is important to make sure they are not leaking.
  • The hub seal (or axle seal) should not be leaking and should be filled to the manufacturer’s specifications.
  • Make sure none of the leaf springs have shifted.
  • Check for leaks under the truck.
  • There should be no lug nuts missing. Look for rust trails, powder residue and cracks around the bolt holes.

The last section is In-Cab Inspection and Brake Tests. For the In-Cab Inspection you will once again want to make sure all of the following components are properly mounted and secure. As well as the following:

Air Brake Test

There are three stages to an air brake test:

  • Applied Pressure Test – When doing the Applied Pressure Test, you will want to build the air pressure to governor cut out. Put the truck in the lowest gear, turn the engine off and immediately turn it back on. Push in the tractor and trailer valves which will then release the parking brakes. Push and hold the brake pedal, allowing the gauges to stabilize. When the gauges have stabilized, announce the Primary and Secondary PSI. Listen for air leaks while doing this.
  • Warning Light and Buzzer – Pump down on the brake pedal until the warning light and buzzer comes on. This is typically at or before 60 PSI.
  • Tractor/Trailer Protection Valve Pop Out – Pump down on the brake pedal until the tractor and trailer protection valves pop out, this will be between 20 and 40 PSI.
  • The air pressure gauges should build to governor cut out.
  • Your truck should have a fire extinguisher, three red reflective triangles and spare electrical fuses.
  • Demonstrate both the heater and defroster are working properly.

Horns (Air Horn and City Horn)

  • Blow both horns to make sure they are working.
  • Check the left turn, right turn, four way flashers and high beams; also point these out on the dashboard.
  • Make sure transmission is in neutral and then fully depress the clutch. Turn the key on, check the ABS light, announce when it comes on and off, and start the engine.
  • The seat belt should not be ripped or frayed and should adjust and latch properly.
  • The engine oil pressure gauge should rise to normal operating range.
  • Trailer Parking Brakes – Set the trailer brake, release the tractor brake, then tug lightly on the trailer.
  • Tractor Parking Brakes – Set the tractor brake, release the trailer brake and tug lightly on the trailer.
  • Release both the tractor and trailer brakes. Drive at idle speed. Apply the service brake to make sure you come to a complete stop and that it doesn’t pull to the left or right when applying the brakes.
  • The voltmeter should be charging between 13 and 14 volts.
  • The water temperature gauge should also rise to normal operating range.
  • The windshield and mirrors must be clean, with no obstructions and in proper adjustment.
  • Demonstrate the wipers and washers are working properly by spraying the windshield.

Back to top of In-Cab Inspection and Brake Tests

During a CDL pre-trip inspection, truckers inspect many aspects of their commercial vehicle, including the overall safety of the vehicle; major hoses, fluid levels, and vehicle belts; the clutch or gear shift; and emergency equipment. The driver demonstrates their knowledge by walking around the vehicle, checking various safety components and explaining why each part should be checked for safety.

Complete CDL Pre-Trip Inspection Checklists for Class A and Class B Drivers

Your fleet is loaded, and the fuel tanks are full – you’re ready to move. Or are you?

If you haven’t completed a pre-trip inspection checklist, you might not be.

The Department of Transportation (DOT) requires all drivers holding a commercial driver’s license (CDL) to complete a pre-trip DOT inspection checklist before operating a commercial vehicle. Usually taking about 10-15 minutes, this inspection checks essential systems such as brakes and steering, as well as tires, mirrors, and emergency equipment.

So how can drivers know what to check? In this article, we’ll run down the DOT requirements for pre-trip inspection checklists, along with key differences between Class A and Class B inspections and even some useful tools that can help make the job easier.

What is a pre-trip inspection checklist?

A pre-trip inspection checklist is a list of items that CDL holders need to review before operating their vehicles. As you may have guessed, this process is known as a pre-trip inspection .

What is a pre-trip inspection?

Pre-trip inspections aren’t just an annoying routine – they’re an important and necessary safety measure that helps ensure that commercial vehicles are up to fleet safety operation standards .

While the scope and contents of a pre-trip inspection checklist vary according to the type of commercial vehicle and its use, you can complete most inspections in about 10-15 minutes. Checklist items generally include assessing the operational condition of anything the driver and vehicle need to operate the vehicle safely . This usually includes things like an air brake check, along with checking lights, tire pressure, couplings, and so on.

Drivers must also record their inspection results in a driver vehicle inspection report (DVIR), which is usually automated (or at least streamlined) in companies with established fleet management tools. Periodic inspection requirements require additional pre-trip inspections every 24 hours of continuous use or whenever the driver changes vehicles.

It may seem like a lot to review, but most of it boils down to common sense. Before you start crawling under the nearest truck, however, you may want to see whether you have to perform a pre-trip inspection in the first place!

Who needs to complete a pre-trip inspection?

Pre-trip inspections are mandatory for both Class A and Class B commercial driver’s license (CDL) holders.

If you’re a CDL holder, you probably already know which Class you fall into. But just in case, here’s a quick refresher on the types and weights of vehicles that different classes of CDL holders can operate.

  • The Class A CDL applies to commercial vehicles weighing at least 26,001 pounds that can tow at least 10,000 pounds. This usually encompasses most towing commercial vehicles such as big rigs, tractor-trailers , and flatbeds.
  • The Class B CDL applies to commercial vehicles weighing at least 26,001 pounds that can tow no more than 10,000 pounds. This usually encompasses most non-towing commercial vehicles, such as passenger buses, garbage trucks, and delivery trucks.

While there is also a Class C CDL, this usually extends to specialty vehicles not found under either Class A or Class B (such as hazardous waste transport). However, since their detailed inspection procedures are highly specific and beyond the scope of this article, we won’t cover them here.

But what’s involved in Class A and Class B inspections, and how can they differ?

Class A vs. Class B pre-trip inspections

While Class A and Class B vehicles share many of the same detailed inspection procedures (every commercial vehicle has brake lights, after all), each class and vehicle type has its own inspection procedures.

  • Class A and Class B commercial vehicles share many common inspection items, such as front and rear suspension, brake lights, minimum brake pad thickness, oil level, etc. These are usually items that apply to any type of road vehicle.
  • Class A inspection items are usually those related to towing systems in commercial vehicles, such as the trailer parking brake, coupling areas, etc. These inspection standards usually extend to the trailer, flatbed, or any other object that the truck is towing.
  • Class B inspection items are usually those related to non-towing commercial vehicles. As this is a very broad category, some Class B vehicles may not require any additional inspections, while others may have several specific systems to inspect. In the case of the latter, these are usually items specific to the vehicle itself, such as checking for broken seat frames in passenger areas of a bus.

Of course, there’s much more to each pre-trip vehicle inspection than the handful of key differences we’ve listed here. In the next section, we’ll run down the pre-trip inspection process that applies to nearly every commercial vehicle and then detail more class-specific motor vehicle safety inspections.

CDL pre-trip inspection checklist

The standard CDL pre-trip DOT inspection checklist includes everything a commercial motor vehicle needs to navigate the road safely.

These are generally suspension- and engine-related items that would just as well apply to a regular car. As a general rule, a commercial pre-trip inspection test almost always includes the following motor vehicle safety inspections.

Brake system

There’s nothing more important than your vehicle’s air brakes. Note that the following air brake tests apply to both tractor brakes and trailer brakes on Class A commercial vehicles.

  • Brake linings and brake pads: Brake pads should be no less than the minimum thickness of one-quarter inch (¼”). Also, be sure to check linings for oil and debris.
  • Brake chamber: The brake chamber should be completely sealed with no audible air leaks.
  • Air brake hose: No air should leak from the brake hose, and the line should be properly mounted and free of cuts or splits.
  • Brake drum: Should not be blue from excessive heat.
  • Hand brake: Push rods should have no more than one inch (1”) of play in either direction and stand up 90 degrees when pulled.

Depending on the vehicle, these items are usually checked with a 9-step, 7-step, or 5-step brake test. These tests usually involve pressing the brake pedal, service brake, hand brake, or foot brake under various conditions and seeing whether air pressure recovers to the proper level in time (see your vehicle’s operating guide).

For example, drivers can check for low air pressure by pressing the brake pedal to fan off the pressure. If repeatedly pressing the brake pedal results in a low pressure buzzer or light indicator, the brake system will require repair.

Engine compartment

Engine compartment inspection items include:

  • Fluids: The coolant hose, power steering hose, and any tanks or reservoirs should all be securely mounted and have no leaks. Similarly, a dipstick should indicate that all fluid levels (including oil level and coolant level) are at their proper levels.
  • Belts: All belts for compressors, pumps, and alternators should have no cracks or frays and give no more than one-half of an inch (½”) of play.
  • Air compressor: Should be securely mounted and functional with no cracks or leaks.
  • Water pump: Pump hoses must be properly connected with no leaks.
  • Alternator: Wires and belts must be properly connected.

Front of vehicle

Front-of-vehicle inspection items usually include steering equipment such as:

  • Steering column or steering shaft: The steering column should be straight and unbroken.
  • Steering box: The steering gearbox should be intact, and all connected hoses should be securely mounted with no power steering fluid leaks.
  • Tie rod and control arms: Both should be straight.
  • Drag link: The rubber should be greased and uncracked.
  • Pitman arm: All cotter pins and caste nuts are present, secure, and tight.

Front suspension

Front suspension inspection items include springs, spring mounts, shocks, and suspension airbags.

  • Spring mounts and spring hangers: Spring mounts should hold spring hangers securely in place with no signs of wear, cracks, or breakage.
  • Leaf springs: Should be secured to hangers with no cracks or breakage.
  • Shock absorbers: Should have no leaks, splits, or dry rot in the rubber. Leaks are typically located where the top and bottom pieces overlap.
  • U-bolts: Should all be securely fastened around the spring and axle.

Rear of vehicle

The rear of tractor or truck inspection items include the following.

  • Driveshaft: Should be straight with unbroken U-joints.
  • Exhaust: Should be free of rust with no leaks or excessive soot.
  • Frame: Structurally sound with no damages or unauthorized repairs/welds.
  • Steps: Structurally sound and mounted properly.
  • Mud Flaps: Should be clean, unbroken, and secured at the right height.

Wheels and tires

Wheel and tire inspections check for both proper inflation and overall tire condition, specifically tread depth. Note that this also extends to trailers on Class A vehicles.

  • Drive and steer tires: Tire tread should be even with a minimum tread depth of 2/32” on drive tires and a minimum tread depth of 4/32” on steering axle tires. Use an air pressure gauge to check inflation levels against manufacturer inflation levels. Treads and sidewalls should be free of cracks, bulges, and abrasions.
  • Wheel rims: No unauthorized repairs or illegal welds.
  • Hub seal and axle seals: Should show the axle and hub seal intact with no visible leaks or play.
  • Dual spacing: Any dual tires must have enough spacing between them.
  • Lug bolt holes: All lug bolt holes should have all lug bolts and lug nuts.
  • Valve stem: No audible air leaks.

Lights and reflectors

Light and reflector inspections include everything from running lights to DOT tape and 4-way emergency flashers.

  • High and low beams: Ensure both are functional on all forward lights.
  • Turn signals: Make sure all are functional for both tractor and trailer.
  • Brake lights: Make sure all are functional for both tractor and trailer.
  • Running lights and license plate lights: Walk around the truck and make sure all are on.
  • 4-way emergency flasher function: Walk around the truck to make sure the 4-way flasher rear and front lights are fully operational.
  • Reflector tape and DOT tape: All DOT tape and reflector tape should be clean with no signs of excessive wear.

Driver door and fuel tanks

Cab doors and fuel tanks are often located in the same area on commercial vehicles. Be sure to check the following:

  • Door and door hinges: Should be intact and latch completely. The rubber door seal should be clean and uncracked.
  • External mirrors and mirror brackets: All external mirrors should be firmly attached to their mirror brackets. External mirrors should also be clean and uncracked. Also, be sure to adjust external mirrors and mirror brackets to provide an adequate rear view.
  • Steps: Should be securely mounted and able to support the weight.
  • Fuel tank: No leaks, with cap and seal unbroken and intact.

In-cab items

Cab inspection usually covers the following items:

  • Steering wheel: Fully attached to steering column.
  • Gauges: Check that air gauges, oil pressure gauges, and any other gauges for operation function normally within their operating range. Air pressure gauges should build pressure to the governor cut out during an applied pressure test.
  • Warning lights: Lights should show clearly for any lighting indicators, such as ABS lights or oil pressure indicators.
  • Windshield: Cracks beyond one inch (1”) are not permitted. Windshield wipers should be clean and work properly, and the truck should have enough windshield washer fluid.
  • Seat belt: Should fasten securely.
  • City horn and air horns: Both air and city horn should sound properly.
  • Heater and defroster: Should heat and function properly.

Special checks for Class A and Class B inspections

As we mentioned earlier, a Class A pre-trip truck inspection will usually have different periodic inspection requirements than, say, a Class B pre-trip school bus inspection.

While periodic inspection requirements ultimately come down to the exact type of vehicle (a Class B garbage truck, for example, may require additional inspections for its armature and compactor), the main differences usually come down to trailers vs. passenger areas .

  • Trailers share many of the same inspection checklist items as the tractor, specifically the wheels and tires, suspension, and rear of trailer lights and reflectors. Also, make sure that the landing gear is not broken and can be fully raised.
  • Coupling area inspections include checking air connectors, electrical lines, and nearby glad hands. All mounting equipment, such as the fifth-wheel plate, kingpin, mounting bolts, skid plate, release arm, and locking jaw and pins, should be present, secure, and in good condition.
  • Rear of truck suspension inspections share many of the same items as those of front inspections but with special attention paid to the torque arm (or radius rod), which should be mounted securely with intact brushings.
  • Passenger items such as seating, passenger doors, and any wheelchair lifts should all be secure and in working order. Emergency exits should also be clearly labeled and sound an alarm when opened.
  • School bus items include all of the passenger items listed above, with the addition of checking student loading lights, stop arm, student rear-view mirror, and a recent first aid and body fluid cleanup kit.

Pre-trip Safety Information for Motorcoach Passengers

Amended basic plan for motorcoach passenger safety awareness, recommended safety topics to be covered.

Emergency exits - Point out the location of all emergency exits (push-out windows, roof vent, and side door) and explain how to operate them. Emphasize that, whenever feasible, the motorcoach door should be the primary exit choice. Encourage able-bodied passengers to assist any injured or mobility-impaired passengers during an emergency evacuation. Provide passengers with sufficient guidance to ensure compliance with 49 CFR 392.62, "Safe operation, buses."

Seat Belt Use - If equipped, recommend the use of shoulder/lap seat belts whenever passengers occupy any seating position.

Emergency Contact - Advise passengers to call 911 by cellular telephone in the event of an emergency.

Driver Direction - Advise passengers to look to the driver for direction and follow his/her instructions.

Fire Extinguisher - Point out the location of the fire extinguisher.

Restroom Emergency Push Button or Switch - Inform motorcoach passengers of the emergency signal device in the restroom.

Avoiding Slips and Falls - Warn passengers to exercise care when boarding and exiting the motorcoach and to use the handrail when ascending or descending steps. Encourage passengers to remain seated as much as possible while the motorcoach is in motion. If it is necessary to walk while the motorcoach is moving, passengers should always use handrails and supports.

Methods of Presenting the Amended Safety Information

The following presentation methods are examples of how to present safety information to motorcoach passengers. The list below should not be construed to restrict combinations of the following methods or additional presentation methods.

1. During passenger boarding - Informational pamphlets or printed materials could be distributed to motorcoach passengers during boarding.

2. After passenger boarding and immediately prior to moving the motorcoach -

  • The driver requests the passengers to review informational pamphlets/printed materials located in the seat back pocket.
  • The driver provides an oral presentation (similar to the presentations by airline flight attendants prior to take-off) with or without informational pamphlets/printed materials as visual aids.
  • An automated presentation over the motorcoach audio system.
  • An automated presentation over the motorcoach video system.

Timing and Frequency of the Presentation

Demand-responsive motorcoach operations, such as charters and tour services, should present the safety information to motorcoach passengers after boarding and prior to movement of the motorcoach.

Fixed route motorcoach service operations should present the safety information at all major stops or terminals, after any new passengers have boarded and prior to movement of the motorcoach.

What is a Pre-Trip Inspection for Class B CDL?

October 22, 2021

Get Started With Samsara

Key Takeaways

Pre-trip inspections are an important part of a driver’s daily routine. For Class B commercial driver’s license (CDL) holders — many of whom drive passenger-carrying vehicles — a pre-trip inspection can help ensure everyone stays safe. Learn more about what’s involved in a Class B pre-trip inspection.

What is a pre-trip inspection?

A pre-trip inspection is a thorough review and examination of a commercial vehicle's major systems and parts before heading out on a route. Completing the pre-trip inspection is one of the most common and important tasks commercial drivers must perform. Drivers have to perform this vehicle inspection at the start of a new day, every 24-hours, and whenever they change vehicles. After completing this inspection, drivers must complete a driver vehicle inspection report (DVIR) recording the completed inspection.

Pre-trip inspections for class B licensees

The class B commercial driver’s license (CDL) covers both passenger carrying and non-passenger vehicles. These might include straight trucks, box trucks, large passenger buses, dump trucks, waste collection trucks, tractor-trailers and more. Depending on the vehicle driven, the class B pre-trip inspection may have slight variations. 

The Department of Transportation (DOT) requires drivers to perform a pre-trip inspection before driving a commercial vehicle. Similar to Class A CDL holders, the actual daily pre-trip inspection takes about 15 minutes or less. Typically, the inspection includes the following with employer and business-specific inspections.

Brakes and air system

Steering mechanism

Lights and reflectors

Tires, wheels, and rims

Windshield wipers

Rearview mirrors

Emergency equipment

Class B CDL pre-trip inspection checklist

When getting a CDL, passing the pre-trip inspection test is much more intensive than the pre-trip inspections drivers perform while on the job. This pre-trip inspection checklist for a Class B CDL gives drivers an overview of what and how to perform an inspection. Check your state’s CDL manual for a complete list of inspection requirements.

Pre-Trip Inspection Study Guide

Blue truck for pre-trip inspection

Our Pre-Trip Inspection Study Guide has everything you need to prepare for the Class A CDL Pre-Trip Inspection Exam . Our study guide will cover the pre-trip inspection terminology as well as a thorough list of all of the parts you will be inspecting on the vehicle. For each part you will be inspecting there will also be a list of items you will be checking for. Our study guide is broken down into the following sections:

  • What You Need to Know About Pre-Trip Inspection

Pre-Trip Inspection Practice Questions

  • Pre-Trip Inspection Checklist

Pre-Trip Inspection Videos

Pre-trip inspection printable resources, what you need to know about the pre-trip inspection.

The Pre-Trip Inspection is a thorough inspection of the vehicle and all of its major systems. Inspecting the vehicle before driving each day is a Federal requirement and normally takes about 15 minutes. It must be logged in your logbook as "on duty not driving."

You will have to do thorough safety inspections of the coupling system, the vehicle lights, engine compartment, tires and brakes, the chassis, the fuel tanks, and an in-cab inspection.

The following information is a brief summary of Daniel's Complete Pre-Trip Inspection taken from our oustanding free PDF download:

Engine Compartment

engine compartment pre-trip inspection

You will be checking the engine compartment for any sort of leaks. You will also be checking to see if all components are properly mounted and secured. None of the mounts must be cracked, bent, or broken.

You will be checking all hoses to make sure they aren't leaking, frayed, or sliced and the fluid levels including the oil level, the coolant, and the power steering fluid.

You must check the components like the water pump, the power steering pump, and the alternator to make sure nothing is leaking, the belts are not frayed, and that everything is properly mounted and secured.

From inside the engine compartment you will also find the steering system, the front suspension system, and the front brake system. All components of these systems must be properly mounted and secured without anything being cracked, bent, or broken. Finally you will be checking the tires, rims, and axle seals to make sure the tires are properly inflated, the rim isn't bent or cracked, and the axle seals are not leaking.

Fuel Tank And Battery Area

air lines connecting tractor to trailer

You will be standing along the side of the tractor doing a series of checks on the mirrors, fuel tanks, batteries, exhaust system, and more. You will check to make sure nothing is bent, cracked, broken, or leaking.

Check the mirrors, door hinges, door handle to make sure nothing is cracked, bent, or broken. Check to make sure there is no fuel leaking and that the fuel cap is secured and the gasket is not missing.

Check the exhaust system to make sure nothing is cracked, bent, or broken. Check the driveshaft, cat walk, and steps to make sure nothing is cracked, bent, or broken.

Check the frame and crossmembers for structural integrity. Check the air lines going to the trailer to make sure they're properly connected and that there are no abrasions, bulges, or cuts. Make sure the gaskets are present.

Check the suspension system and brakes on the drive axles, making sure nothing is cracked, bent, or broken. Make sure the brake linings are the proper thickness and that the air bags and properly inflated. Inspect the brake chambers, slack adjusters, and pushrods are properly mounted and secure. Not Cracked, Bent, or Broken. With the brakes released and pulled by hand, the Push Rod should not move more than 1 inch.

Check the rims, tires, and axle seals of the drive tires for proper inflation, no leaks around the seal, and the lugs are all present and secured.

Coupling System

air brake lines connecting the tractor to trailer checked for pre-trip inspection

You will be standing where the tractor and trailer are connected and you'll start by checking the electrical line and air lines to make sure they're properly mounted and secure at both ends. No abrasions, bulges or cuts. Not leaking air. Make sure the electrical line has no wires exposed. Check the gladhands to make sure the seals are in good condition, no cracks or signs of dry rotting. Not leaking air.

Check the skid plate of the fifth wheel and the apron of the trailer to make sure there is no debris and nothing is cracked, bent, or broken. Make sure the fifth wheel is properly greased. Also make sure there is no gap in between the fifth wheel and the trailer apron once the tractor and trailer are coupled. Make sure the kingpin of the trailer is properly mounted and not cracked, bent, or broken and that the locking jaws of the fifth wheel are properly secured when the tractor and trailer are coupled.

Check the mounting bolts where the fifth wheel attaches to the tractor frame. Make sure there are no missing bolts and that everything is secured properly. Check the locking pin if you having a sliding fifth wheel to make sure it's properly locked into place.

Make sure that there is the proper clearance space between the tractor mudflap and the trailer landing gear so that they don’t hit each other when making a turn.

tandem frame and connecting pins are properly locked for pre-trip inspection

You will start inspecting the trailer at the head board, which is the front wall of the trailer. Make sure there are no holes or missing rivets. Check the landing gear to make sure it is properly mounted and secure. Not cracked, bent, or broken. Make sure the fully raised and the handle is secure in the cradle when the tractor and trailer are coupled.

Check the frame and crossmembers under the trailer to make sure they're not cracked, bent, or broken. Check the tandem frame and release pins to make sure the frame is in good condition and the release handle and locking pins are in the fully locked position.

You will check the entire suspension and brake system for the trailer tandems the same way you did for the drive axles of the tractor. You will also make sure the mudflaps are properly secured. For dual tires check to see that there is proper space between the tires and there is nothing stuck between the tires.

Check the rear door and hinges to make sure they are properly mounted and nothing is cracked, bent, or broken. Make sure the door seals are not worn, torn, or dry rotted.

Light Check

lights on the back of the trailer during pre-trip inspection

You will be checking all of the lights and reflectors on both the tractor and the trailer. Check the reflectors and reflective tape to make sure they are properly mounted and secure, not cracked, bent, or broken, and clean and illuminated. Check that you have the proper color of amber to the front and sides, and red to the rear.

Start by turning on your marker lights and headlights. Now walk around the entire truck and trailer and point out the lights. Give the function of the light and the location. You should then ask your examiner to help you check your five functions.

While you're sitting in the drivers seat, the examiner will stand to the front of the truck, then behind the trailer. He will then check your Turn Signals, Four Way Flashers and Brake Lights. You must do each function at every location.

The five locations that you must check your lights:

  • Front of the Truck
  • Both sides of the Truck
  • Rear of the Truck
  • Both sides of the Trailer
  • Rear of the Trailer

The Five Functions you are checking for:

  • Left Turn Signal
  • Right Turn Signal
  • Four Way Flashers
  • High Beams/Low Beams
  • Brake Lights

In-Cab Inspection

The in-cab inspection and air brake check will cover the various gauges and systems inside the cab along with several tests to make sure you air brake system is working properly.

You will start by checking the following:

  • Seat Belt- Properly Mounted and Secure. Not ripped or frayed Adjusts and latches properly.
  • Fire Extinguisher- Properly Mounted and Secure. Fully charged
  • Three Red Reflective Triangles- My three red reflective triangles are GIVE LOCATION
  • Spare Electrical Fuses- My spare electrical fuses are GIVE LOCATION

  • Heater and Defroster - Demonstrate that both the Heater and Defroster are working properly.
  • Lighting Indicators - Left Turn, Right Turn, Four Way Flashers, and High Beams.

Trailer Parking Brakes - Set the Trailer Brake, release the tractor brake, and then tug lightly on the trailer.

Tractor Parking Brakes- Then set the Tractor Brake, release the trailer brake, and then tug lightly on the tractor.

Service Brake Check - Release both Tractor and Trailer Brakes. Now drive at idle speed. Apply the Service Brake to make sure you come to a complete stop, and that it doesn't pull to the left or right when applying the brakes.

Air Brake Test

in-cab air brake test during pre-trip inspection

The air brake test will consist of a leakdown test to make sure your air brakes aren't leaking air and losing pressure. It will also test the warning lights and buzzer to make sure the driver gets the proper warning if the air pressure drops too low.

There are three stages to an Air Brake Test

#1: Applied Pressure Test

#2: Warning Light and Buzzer

#3 Tractor/Trailer Protection Valve Pop Out

Applied Pressure Test: Build the air pressure to governor cut out. Put the truck in the lowest gear. Then turn off the engine Immediately turn the engine back on. Push in both the tractor and trailer valves. (This will release the parking brakes.) Push and hold the Brake pedal fully. Allow the gauges to stabilize. Announce the gauges have stabilized and the Primary and Secondary PSI. With the Brakes fully pressed, you should not lose more than 4 PSI in one minute. Announce that you are listening for air leaks during that minute.

Warning Light and Buzzer Test: Pump down on the Brake pedal until the warning light and buzzer comes on, at or before 60 PSI.

Tractor/Trailer Protection Valve Pop Out Test: Pump down on the brake pedal until both the tractor and trailer protection valves pop out. They should both pop out between 40 and 20 PSI.

We have a ton of Pre-Trip Inspection Practice Questions along with the answers and a complete scoring system in our Free Online CDL Practice Tests :

The Engine Compartment Section will include questions about checking the oil level and coolant levels, inspecting belt-driven engine components (like the water pump, alternator, and air compressor), and the safety devices required in the cab. There will also be questions regarding the windshield wipers and free play in the steering wheel.

The Lights And Brakes Section will include questions about dashboard indicator lights, inspecting the parking brakes, and doing a leakdown test on the air brakes. It will also include questions about the low air pressure warning signal and testing your air horn and city horn.

The Suspension And Steering Section will include questions about the tractor protection valve, inspecting the steering box, and inspecting many suspension system parts. It will also include questions about welds being present on tire rims and the minimum tread depth required on steering axle tires.

The Tires And Coupling Devices Section will include questions about shiny trails or rusty threads on lug nuts, inspecting the battery box and cover, and inspecting electrical lines. It will also contain questions about inspecting the coupling devices and the fifth wheel skid plate.

The Emergency Equipment And Fifth Wheel Section will include questions about additional emergeny equipment required by school buses, inspecting the gap between the kingpin apron and the fifth wheel skid plate, and the landing gear securement. It will also contain questions about inspecting driver mirrors and the trailer frame.

Pre-Trip Inspection Checklist - Class A

Medvedev joins Moscow Metro passengers for on-site inspection

Medvedev joins Moscow Metro passengers for on-site inspection

Dmitry Medvedev has inspected a Moscow Metro station, where a pilot security project improving law enforcers’ ability to counter terrorist threats has been implemented.

The Russian president and a group of ministers responsible for transport and security in Russia went underground at the Okhotny Ryad station in central Moscow, side-by-side with everyday commuters.Medvedev tested the newly-installed systems for x-ray screening of passengers and luggage and the safe scanning and disarming of suspected explosive devices, which allows a bomb to be disabled without the evacuation of people and closure of the station. He also tried the emergency paging terminal, which allows instant calls to station security.The measures are to be tested before similar equipment is installed at some 50 stations of Moscow Metro system. Medvedev ordered the security upgrade in March 2010 after the suicide bombing at two Metro stations.

Why do tourists choose buses and shuttle buses to get Elektrostal Moscow train station «Belorussky»

This route is popular among both tourists and the locals of Russia, and is operated by many types of public transport. Buses and tourist shuttles are the good option for those who are travelling alone or with a friend, for young people, who feel familiar with the country and speak its language as well as for those who would like to reduce the costs of their holiday.

Buses and shuttles vs. other types of public transport

The cheapest variant. Moneywise, a bus ride is either equal to other types of public transport (for example, suburban train), or 5–15% cheaper than any of these options.

Easy to change. A bus brings you to the stop, from which it is easy to get to your destination: in case of a tourist shuttle, it might even bring you to your hotel. Regular buses start off from the large transport hubs, heading to the most popular directions, and run through the central districts of the neighbouring towns and resorts. For example, the bus from the airport stops at the stop from which it is easy to get to your destination with maximum one change. Kiwitaxi tourist shuttles bring tourists to their holiday destinations, and not just drop them in the city center.

A small excursion during the trip. Buses go slowly and make stops. On some tourist shuttles there are attendants, who help pass the time by telling about the sights.

Disadvantages of buses compared to other types of public transport

Full in rush-hour. Buses are the most available variant, and most of tourists, who are not ready to spend money on taxi, use it. You are likely to travel with your luggage on your knees or even standing. Group shuttles are filled up evenly, so the lack of seats is almost impossible. However, there might be not enough room for the baggage.

Tickets are not always available. The reason is the same — buses in Russia are a popular type of transport, so the tickets should be bought in advance as there might not be any on site.

Booking tickets for Kiwitaxi shuttles Elektrostal in advance, you eliminate both disadvantages of buses.
