This CDL Vehicle Inspection Test represents the July 2017 version of the Section 11 "Vehicle Inspection Test" of the Commercial Driver's License Manual adopted by the state of Virginia. The manual was developed for the 2005 CDL Testing System.


Section 11 introduction

Purpose

During the Vehicle inspection, you must show that the vehicle is safe to drive. You will have to walk around the vehicle, name and point to/ touch each item and explain to the examiner what you are checking and why.

Restrictions

Any vehicle that has components marked or labeled cannot be used for the Vehicle Inspection test.

Scope

This Section covers:
  • Internal Inspection
  • External Inspection

All Vehicles (11.1)

Study the following vehicle parts for the type of vehicle you will be using during the CDL skills tests. You should be able to identify each part and tell the examiner what you are looking for or inspecting.

Engine Compartment (Engine Off; 11.1.1)

Leaks/Hoses
  • Look for puddles on the ground.
  • Look for dripping fluids on underside of engine and transmission.
  • Inspect hoses for condition and leaks.
Oil Level
  • Check oil level when engine is off.
  • Indicate where dipstick is located.
  • Check that the oil level is within safe operating range. Level must be above refill mark.
Coolant Level
Looks at sight glass on radiator or coolant reservoir; adequate level will show in sight glass. If no sight glass is available, you must describe what s/he would look for after removing radiator cap.
Power Steering Fluid
Checks the dipstick and sees where the fluid level is relative to the refill mark or checks sight glass. Level must be above refill mark.
Engine Compartment Belts
Check the following belts for snugness (1/2 to 3/4 inch play at center of belt), cracks, frays, loose fibers or signs of wear:
  • Power steering belt.
  • Water pump belt.
  • Alternator belt.
  • Air compressor belt.
Note: If any of the components listed above are not belt driven, you must:
  • Tell the examiner which component(s) are not belt driven.
  • Make sure component(s) are operating properly, are not damaged or leaking, and are mounted securely.
Safe Start
  • Place gearshift lever in neutral (or park, for automatic transmissions).
  • Depress clutch before attempting to start the vehicle.
  • Start the vehicle and keep clutch depressed until engine reaches idling speed.
  • Then release clutch slowly.

Cab Check/Engine Start (11.1.2)

Oil Pressure Gauge
Make sure oil pressure gauge is working. Check that pressure gauge shows increasing or normal oil pressure or that the warning light goes off. If equipped, oil temperature gauge should begin a gradual rise to the normal operating range.
Temperature Gauge
Make sure the temperature gauge is working. Temperature should begin to climb to the normal operating range or temperature light should be off.
Air Gauge
Check that the air gauge is working properly and that the air compressor builds the air pressure to governor cut-out at approximately 120-140 psi or as specified by manufacturer.
Ammeter/Voltmeter
Check that gauges show alternator and/or generator is charging or that warning light is off.
Mirrors and Windshield
  • Mirrors should be clean and adjusted properly from the inside.
  • Windshield should be clean with no illegal stickers, no obstructions, or damage to the glass.
Emergency Equipment
  • Check for spare electrical fuses.
  • Check for three red reflective triangles and 6 fusees or 3 liquid burning flares.
  • Check that the fire extinguisher is properly charged and securely mounted.
Note: If the vehicle is not equipped with electrical fuses, you must mention this to the examiner.
Wipers/Washers
Check that wiper arms and blades are secure, not damaged, and operate smoothly. If equipped, windshield washers must operate correctly.
Lights/Reflectors/Reflector Tape Condition (Sides & Rear)
Test that dash indicators work when corresponding lights are turned on:
  • Left turn signal.
  • Right turn signal.
  • Four-way emergency flashers.
  • High beam headlight.
  • Anti-lock Braking System (ABS) indicator.
Check that all external lights and reflective equipment are clean and functional and none or broken or missing. Light and reflector checks include verification of correct color:
  • Clearance lights (red on rear, amber elsewhere).
  • Headlights (high and low beams).
  • Taillights.
  • Backing lights.
  • Turn signals.
  • Four-way flashers.
  • Brake lights.
  • Red reflectors (on rear) and amber reflectors (elsewhere).
  • Reflector tape condition
Note: Checks of brake, turn signal and four-way flasher functions must be done separately.
Horn
Check that air horn and/or electric horn work.
Heater/Defroster
Test that the heater and defroster work.
Parking Brake Check
  • With air pressure built to governor cutout and the parking brake engaged (trailer brakes released on combination vehicles), check that the parking brake will hold vehicle by gently trying to pull forward with parking brake on.
  • With air pressure built to governor cutout, the parking brake released and the trailer parking brake engaged (combination vehicles only), check that the trailer parking brake will hold vehicle by gently trying to pull forward with the trailer parking brake on.
Hydraulic Brake Check
  • Pump the brake pedal three times, then hold it down for five seconds. The brake pedal should not move (depress) during the five seconds.
  • If equipped with a hydraulic brake reserve (back-up) system, with the key off, depress the brake pedal and listen for the sound of the reserve system electric motor.
  • Check that the warning buzzer or light is off.
Air Brake Check (Air Brake Equipped Vehicles Only)
Failure to perform all three components of the air brake check correctly will result in an automatic failure of the vehicle inspection test. Air brake safety devices vary. However, this procedure is designed to see that any safety device operates correctly as air pressure drops from normal to a low air condition. For safety purposes, in areas where an incline is present, you will use wheel chocks during the air brake check. The proper procedures for inspecting the air brake system are as follows:
  1. With the air pressure built up to governor cutoff (120 – 140 psi), shut off the engine leaving the key in the “on” or “battery charge” position, chock your wheels if necessary, release the parking brake (all vehicles), and the tractor protection valve (combination vehicle) and fully apply the foot brake. Hold the foot brake for one minute. Check the air gauge to see if the air pressure drops more than three pounds in one minute (single vehicle) or four pounds in one minute (combination vehicle).
  2. Begin fanning off the air pressure by rapidly applying and releasing the foot brake. Low air warning devices (buzzer, light, flag) should activate before air pressure drops below 55 psi or level specified by the manufacturer.
  3. Continue to fan off the air pressure. At approximately 40 psi on a tractor-trailer combination vehicle (or level specified by the manufacturer), the tractor protection valve and parking brake valve should close (pop out). On other combination vehicle types and single vehicle types, the parking brake valve should close (pop out).
Service Brake Check
You will be required to check the application of air or hydraulic service brakes. This procedure is designed to determine that the brakes are working correctly and that the vehicle does not pull to one side or the other. Pull forward at 5 mph, apply the service brake and stop. Check to see that the vehicle does not pull to either side and that it stops when brake is applied.
Safety Belt
Check that the safety belt is securely mounted, adjusts, latches properly and is not ripped or frayed.

Taking the CDL Vehicle Inspection Test (11.6)

Class A Vehicle Inspection Test (11.6.1)

If you are applying for a Class A CDL, you will be required to perform one of the four versions of a Vehicle inspection in the vehicle you have brought with you for testing. Each of the four tests are equivalent and you will not know which test you will take until just before the testing begins.
All of the tests include an engine start, an in-cab inspection, and an inspection of the coupling system. Then, your test may require an inspection of the entire vehicle or only a portion of the vehicle which your CDL Examiner will explain to you.

Class B and C Vehicle Inspection Test (11.6.2)

If you are applying for a Class B CDL, you will be required to perform one of the three versions of a Vehicle inspection in the vehicle you have brought with you for testing. Each of the three tests are equivalent and you will not know which test you will take until just before the testing begins.
All of the tests include an engine start and an in-cab inspection. Then, your test may require an inspection of the entire vehicle or only a portion of the vehicle which your CDL Examiner will explain to you. You will also have to inspect any special features of your vehicle (e.g, school or transit bus).
