Georgia CDL: Pre-Trip Inspection Practice Test

Not quite. The answer is the windshield wipers and washer

Check that the windshield wiper blades are in good condition and press hard enough against the windshield to keep it clean without excessive streaking. Also make sure that the windshield washer mechanism works and there is enough windshield washer fluid in the reservoir.

Not quite. The answer is the parking brakes

Test the parking brakes first. Then to test the service brakes, start by releasing the parking brakes.

Not quite. The answer is Lug nuts

During your pre-trip inspection, check that all lug nuts are present and accounted for, tightly fastened, and free of cracks or distortions.

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 Hydraulic brakes

If your vehicle has hydraulic brakes, test them by pumping the brake pedal three times and then applying firm pressure to it for five seconds, making sure the pedal does not move during that time. If your vehicle has air brakes, test them by performing the final air brake check as described in the Georgia Commercial Drivers Manual.

Not quite. The answer is the parking brake

The parking brake is meant to keep your vehicle from moving. The best way to test it is to apply the brake and then try to pull forward gently. The parking brake should hold your vehicle in place.

Not quite. The answer is Steering box

When you turn the steering wheel, the steering box translates this motion into turning the front wheels. During your pre-trip inspection, check that the steering box is in good condition, securely mounted, and not leaking. Also check that no nuts, bolts, or cotter keys are missing.

Not quite. The answer is While the parking brake is applied

The parking brake is meant to keep your vehicle from moving. The best way to test it is to apply the parking brake and then try to pull forward gently. The parking brake should hold your vehicle in place. If you're pulling one or more trailers, test each trailer's parking brakes in the same way.

Not quite. The answer is Excessive steering wheel play can make it hard to steer.

If there is more than 10 degrees of play in your steering wheel, it will be harder for you to tell which way your front wheels are pointed. Have the problem corrected before you drive the vehicle. Ten degrees is equivalent to about 1¾ inches at the rim of a 20-inch steering wheel. According to federal regulations, there must not be more than 2½ inches of play at the rim of a 20-inch steering wheel.

Not quite. The answer is Release arm

The release arm allows you to disengage the fifth-wheel locking jaws so you can uncouple the trailer. During your pre-trip inspection, check that the release arm is in the engaged position and the safety latch (if so equipped) is in place.

Not quite. The answer is Over the trailer bumper; hooks face downward

During your pre-trip inspection, make sure that the safety chains are crossed (if they are long enough for that). Make sure that the safety chains are hooked over the trailer bumper and onto the trailer so that the hooks face downward.

Not quite. The answer is any of the above

When you check the engine compartment, make sure the engine is off. In this step, you check a number of things, including checking the air compressor, water pump, and hoses for leaks.

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 Doors

During your pre-trip inspection, check that the doors to your vehicle are undamaged and that they open and close properly from the outside. The hinges should be secure with seals intact. Note: If you're inspecting a passenger vehicle, there are additional checks you should perform on the passenger entry doors and the emergency exit doors.

Not quite. The answer is The windshield and mirrors

Windshields and mirrors should be clean and free of damage, illegal stickers, or obstructions that could impede visibility.

Not quite. The answer is Air compressor

The air compressor maintains air pressure for the air brakes by pumping air into the air storage tanks. If your vehicle's air compressor is belt driven, make sure that its drive belt is snug. A belt that is too loose might slip and not drive the air compressor properly.

Not quite. The answer is Both of the above

There are many things you must check during your pre-trip inspection. In Step 5 (Walkaround Inspection) of the Seven-Step Inspection Method, you'll check many items around the vehicle, including the cargo securement and the condition of the windshield wipers.

Not quite. The answer is the special features of the vehicle.

Class B and Class C CDLs cover the operation of a wide variety of different types of vehicles with their own special features. You must perform the vehicle inspection test on a vehicle that is representative of the kinds of vehicles that you plan to drive professionally. As part of the test, you will have to inspect any special features of your vehicle (such as the special features of school buses if you're using one for the test).

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

The CDL skills test comprises three parts: the pre-trip inspection test, the basic control skills test, and on-road driving (the road test). Applicants fail the pre-trip inspection more than any other part of the CDL skills test. There's a lot to remember. 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 Poisonous fumes can enter the cab or sleeping compartment.

The exhaust system is designed to help remove toxic gases produced by the engine. A leak in the exhaust system can allow poisonous carbon monoxide (CO) to seep into the cab or sleeping compartment. A buildup of CO is more likely in cold weather, when you may have the cab windows closed.
