Sample Georgia CDL Test Questions - General Knowledge

Question 1

Leaving a retarder on when the road is wet or icy helps prevent the drive wheels from skidding.

  1. A TRUE
  2. B FALSE

Correct answer: B – FALSE

A retarder does not protect against skidding on a slippery surface. Because its braking force acts on the drive wheels, poor traction can cause those wheels to skid. Turn the retarder off when the roadway is wet, icy, or covered with snow, and adjust speed and braking to the available traction.

Question 2

Which conditions are brake defects that should be found during a vehicle inspection?

  1. A Cracked brake drums
  2. B Oil, grease, or brake fluid on shoes or pads
  3. C Dangerously thin, missing, or broken shoes
  4. D All of these conditions

Correct answer: D – All of these conditions

Georgia CDL inspection guidance identifies cracked drums, contaminated shoes or pads, and dangerously thin, missing, or broken shoes as brake problems. Cracks can weaken a drum, while oil, grease, or brake fluid reduces the friction needed for braking. Worn or damaged shoes may also prevent the brake from operating effectively. Every listed condition requires attention.

Question 3

How should the trailer hand valve be used?

  1. A Use it only to test the trailer brakes, not for routine braking while driving
  2. B Apply it before the foot brake to reduce skidding
  3. C Use it for normal stops whenever the trailer is loaded
  4. D Use it as the primary brake when stopping in a straight line

Correct answer: A – Use it only to test the trailer brakes, not for routine braking while driving

The trailer hand valve operates only the trailer brakes and should be used only for testing them. Using it for routine braking can lock the trailer wheels and cause the trailer to skid or jackknife. The foot brake applies the brakes throughout the combination and presents much less danger of producing a trailer skid.

Question 4

What causes most serious commercial-vehicle skids?

  1. A Driving too fast for roadway conditions
  2. B Minor differences in brake adjustment
  3. C Carrying excessive weight on the steering axle
  4. D Using tires from different manufacturers

Correct answer: A – Driving too fast for roadway conditions

Most serious skids result from traveling too fast for the existing road conditions. Excessive speed can force a driver to brake, steer, or accelerate beyond the available traction. By reducing speed for weather and roadway conditions, a driver is less likely to over-brake, over-steer, or spin the drive wheels.

Question 5

A driver may transport liquid or gas in a tank after discovering that the tank is leaking.

  1. A TRUE
  2. B FALSE

Correct answer: B – FALSE

Georgia’s official CDL manual directs drivers not to carry liquids or gases in a leaking tank and states that doing so is a crime. Before loading, unloading, or driving, inspect under and around the tank for leakage. The tank shell, valves, pipes, connections, hoses, manhole covers, and vents should all be checked.

Question 6

Which preparation is appropriate before operating a CMV in freezing weather?

  1. A Use antifreeze formulated for the windshield-washer system
  2. B Apply bleach to the tires for additional traction
  3. C Remove coolant antifreeze when temperatures fall below freezing
  4. D Ignore small exhaust leaks because the windows will be closed

Correct answer: A – Use antifreeze formulated for the windshield-washer system

Use windshield-washer antifreeze to keep the washer fluid from freezing. Wiper blades, washers, defrosters, and heaters should be checked before winter operation because clear visibility is essential. Exhaust leaks also require attention, especially when the cab is closed, because carbon monoxide can enter the vehicle through a defective exhaust system.
