Hawaii CDL: Pre-Trip Inspection Practice Test

Not quite. The answer is All of the above

The external lights that should be checked include the following: high- and low-beam headlights, clearance lights, taillights, backing lights, four-way emergency flashers, left and right turn signals, red and amber reflectors, and brake lights.

Not quite. The answer is do either (a) or (b).

If the coolant overflow container is not part of the pressurized system, you can remove the cap to check the coolant level even when the engine is hot. Alternatively, some vehicles have sight glasses to let you check the coolant level. Note: Never attempt to remove the radiator cap or any other part of the pressurized system until the system has cooled thoroughly. While it's hot, pressurized steam or boiling water can spray out and injure you.

Not quite. The answer is Parking brake

The parking brake keeps your vehicle from moving when it's parked. The mechanism is separate from the service brakes that you use in normal driving.

Not quite. The answer is make sure it is securely mounted.

When checking the alternator, check that it is securely fastened. Check that all wires are undamaged and securely fastened. Check that the belt is in good condition and the belt deflection is between 1/2 inch and 3/4 inch.

Not quite. The answer is If you fail one part of the skills test, you'll have to retake the entire test next time.

Applicants fail the pre-trip inspection more than any other part of the CDL skills test. There's a lot to remember, and you may not be allowed to take a pre-trip inspection checklist or any other "cheat sheet" with you to the test. You will be provided with an official checklist you can use. Inspecting your vehicle in the same order each time will help you remember the steps both for your skills test and in your commercial driving career. If you fail any part of the skills test, you will have to take the entire skills test again and pay additional fees.

Not quite. The answer is Shock absorbers

During your pre-trip inspection, check the shock absorbers on every axle of your vehicle (including the trailers if any) to be sure that they are securely mounted and not leaking.

Not quite. The answer is Fire extinguisher and warning devices for stopped vehicles

Federal regulations require every CMV to carry one of the following sets of warning devices in case the driver must stop the CMV on the road: three reflective triangles and a fire extinguisher. Spare electrical fuses are no longer federally required emergency equipment under current FMCSA regulations. States may require extra emergency equipment on certain vehicles.

Not quite. The answer is Frame

The frame consists of the structural members for supporting the body of the vehicle or trailer. When inspecting the frame, (1) check for cracks; (2) check for broken welds; and (3) check for illegal holes or other damage to the longitudinal frame members, cross members, box, or floor.

Not quite. The answer is Landing gear

You check the landing gear when you inspect the side of the trailer.

Not quite. The answer is do all of the above.

As part of your vehicle inspection test, if your vehicle is equipped with a cargo lift, explain how to check it for correct operation. Check for leaking, damaged, or missing parts. Also check that the cargo lift is fully retracted and securely latched.

Not quite. The answer is splash guards (mud flaps)

Always check that all splash guards (mud flaps) are securely mounted and in good condition. Currently, there are no federal requirements on splash guards. Each state is free to issue its own regulations. In the state of Hawaii, Hawai'i County, Honolulu, Kaua'i, and Maui require every motor vehicle, trailer and semitrailer to have fenders, mudguards, wheel covers, or other devices that can minimize the spray or splash of water or mud to the rear of the vehicle. However, none of these counties specifies a maximum ground clearance for such devices. [Hawai'i CC § 24-105], [ROH § 15-19.32], [Kaua'i CC § 16-17.31],

Not quite. The answer is Every axle

Be prepared to perform a brake components inspection on every axle. You may need to perform a suspension components inspection on every axle, too.

Not quite. The answer is Landing gear

The trailer landing gear is a set of retractable legs that support the trailer when it is parked. During your pre-trip inspection, check that the landing gear is fully raised and no parts are missing. Check that the crank handle is secure and the support frame is undamaged. If the landing gear is power operated, check it for air or hydraulic leaks.

Not quite. The answer is Steering axle tires

The tires on the steering axle should have at least 4/32 inch of tread, and all other tires should have at least 2/32 inch of tread. Inadequate tread on the front tires increases the risk of a front-wheel skid.

Not quite. The answer is the service brake

To test the service brakes, pull forward at 5 mph and then apply the service brake. Unless the brakes are wet, they should apply evenly and not pull the vehicle to one side or the other. If your vehicle pulls to one side or the other, the service brakes may need repair.

Not quite. The answer is Spacers

Wheel spacers adjust wheel offset. During your pre-trip inspection, inspect each wheel that has wheel spacers to make sure that no spacers are missing, bent, damaged, or rusted through. Make sure that dual tires aren't touching. Dual tires that touch can catch fire.

Not quite. The answer is So no one drives the vehicle while you are inspecting under it.

Take the starter key with you during the inspection so no one can drive your vehicle while you are inspecting under it.

Not quite. The answer is the trailer parking brake

Even after you release the truck or tractor parking brake, the trailer parking brake should still hold your vehicle in place when you try to pull forward gently.

Not quite. The answer is Dash indicators

During your pre-trip inspection, test that the dash indicators work when the following corresponding lights are turned on: the left turn signal, the right turn signal, the four-way emergency flashers, and the high-beam headlights.

Not quite. The answer is Platform

During your pre-trip inspection, check that there are no cracks or other damage to the platform structure that supports the fifth wheel skid plate.
