Section 10: Pre-Trip Test
This section will assist drivers taking the pre-trip test.
A pre-trip inspection should be done the same way each time so you will learn all the steps and be less likely to forget something.
Before the pre-trip test, the examiner will check the brake lights, emergency flashers, turn signals, horn, and splash guards (if required). If any of these items do not work, the test will be postponed.
During the pre-trip test, you must show that the vehicle is safe to drive. You may have to walk around the vehicle and point to or touch each item and explain to the examiner what you are checking and why. You will NOT have to crawl under the hood or under the vehicle.
You may only use one of the guides shown here or here when taking your pre-trip test. The memory aid cannot include instructions on how to perform the pre-trip inspection. If you do not pass the pre-trip inspection test, the other tests will be cancelled.
Remember: You are allowed a total of three attempts to pass the pre-trip, skills, or driving tests. (Here for more information)
All Vehicles
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.
Vehicle Overview
As you approach the vehicle, notice its general condition. Look for damage or if the vehicle is leaning to one side. Look under the vehicle for fresh oil, coolant, grease, or fuel leaks. Check area around the vehicle for hazards to vehicle movement such as people, other vehicles, objects, low hanging wires, or limbs, etc.
Check the parking brakes are set and/or wheels chocked. You may have to raise the hood, tilt the cab (secure loose objects so they don’t fall and break something), or open the engine compartment door. Check the following:
Engine Compartment (Engine Off)
Leaks/Hoses (fuel, coolant, oil, power steering fluid, hydraulic fluid, battery fluid, etc.)
Look for puddles on the ground.
Look for dripping fluids on underside of engine and transmission.
Inspect hoses for condition and leaks.
Oil Level
Indicate where dipstick is located
See that oil level is within safe operating range. Level must be above refill mark.
Coolant Level
Inspect reservoir sight glass, or
(If engine is not hot), remove radiator cap and check for visible coolant level.
Power Steering Fluid
Indicate where power steering fluid dipstick is located.
Check for adequate power steering fluid level. Level must be above refill mark.
Windshield Washer Fluid Level
Check fluid level and cap secure
Automatic transmission fluid level (may require engine to be running)
Engine Compartment Belts
Check the following belts for snugness (up to 3/4 inch play at center of belt), cracks, frays, or excessive 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.
Cab Check/Engine Start
Get in and start the engine.
NOTE: Ensure engine compartment hood is closed and latched. Cab-over-primary and safety locks engaged.
Clutch/Gearshift
Make sure the parking brake is set.
Depress clutch.
Place gearshift lever in neutral (or park, for automatic transmissions).
Start engine, then release clutch slowly.
Accelerator checked for looseness, sticking, or damage.
Listen for unusual engine noises.
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.
Coolant 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.
Ammeter/Voltmeter
Check that gauges show alternator and/or generator is charging or that warning light is off.
Oil Temperature Gauge
Check that gauge begins gradual rise to normal operating range.
Mirrors and Windshield
Mirrors should be clean and adjusted properly from the inside.

Check for a properly charged and rated fire extinguisher.
Check Optional Emergency Equipment
Tire chains (where winter conditions require them)
Tire changing equipment
List of emergency phone numbers
Accident reporting kit (packet)
Steering Wheel
Check for looseness, sticking, or damage.
Steering Play
Non-power steering: Check for excessive play by turning steering wheel back and forth. Play should not exceed 10° (or about two inches on a 20-inch wheel).
Power steering: With the engine running, check for excessive play by turning the steering wheel back and forth. Play should not exceed 10° (or about two inches on a 20-inch wheel) before front left wheel barely moves.
Wipers/Washers
Check that wiper arms and blades are secure, not damaged, and operate smoothly.
If equipped, windshield washers must operate correctly.
Lighting Indicators
Test that dash indicators work when corresponding lights are turned on:
— left and right turn signals

Hydraulic Brake Check
Pump the brake pedal three times, then hold it down for five seconds. The brake pedal should not move during the five seconds.
If equipped with a hydraulic brake reserve system, with the key off, depress the brake pedal and listen for the sound of the reserve system electric motor.
If equipped with a “Hydro—Boost” brake system, release the parking brake and with the engine off, depress and release the brake pedal several times to deplete all hydraulic pressure. Depress and hold the brake pedal with light pressure (15–25 lbs) then start the engine and run it at idle speed. If the Hydro—Boost is operating, the pedal will yield slightly to foot pressure and then hold. Less pressure is required to hold the pedal at this position.
Check that the warning buzzer or light is off.
Air Brake Check (for air brake equipped vehicles only)
For DMV testing purposes:
Failure to perform a complete air brake check as indicated in Section 5 (In-Cab Air Brake Check) will result in an automatic failure of the pre-trip 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:
— with the engine running, build the air pressure to governed cutout (100_125 p.s.i., 130 p.s.i. maximum). Identify when the compressor cuts out.
— shut off the engine, chock your wheels, if necessary, release the tractor protection valve and parking brake and allow the system to settle. Fully apply the foot brake and allow the system to settle. Hold it for one minute, check the air gauge to see if the air pressure drops more than 3 p.s.i. for a single vehicle or 4 p.s.i. for a combination vehicle. Identify if the loss is too high.
— start engine and begin fanning down the air pressure by applying and releasing the foot brake. Identify when the compressor cuts in.
— continue to fan the brakes to check when the low air warning device activates. Identify when the device activates. Low air warning devices should activate in compliance with federal regulations or not lower than 55 p.s.i. or higher than 75 p.s.i.
