Sample Georgia CDL Test Questions - General Knowledge

Question 1

Which list contains driving errors associated with alcohol impairment?

  1. A Slower response to hazards
  2. B Driving too fast, too slowly, or in the wrong lane
  3. C Weaving or running over a curb
  4. D All of these

Correct answer: D – All of these

The Georgia CDL guide lists increased reaction time, improper speed, wrong-lane driving, curb strikes, and weaving as serious errors caused by alcohol. Alcohol impairs judgment, vision, coordination, and reaction time even before a driver recognizes the impairment. Because every listed behavior is associated with alcohol-impaired driving, all three individual choices are correct.

Question 2

During emergency controlled braking, how should brake pressure be applied?

  1. A Lock the wheels and hold the pedal down until stopped
  2. B Apply the brakes firmly without allowing the wheels to lock
  3. C Apply full pressure until the wheels lock, then repeatedly release and reapply
  4. D Avoid this technique on every heavy vehicle

Correct answer: B – Apply the brakes firmly without allowing the wheels to lock

During controlled braking, apply the brakes as hard as possible without locking the wheels. Keep steering corrections small while braking. If the wheels lock or a larger steering movement becomes necessary, release the brakes and apply them again when possible. Intentionally locking and releasing the wheels describes stab braking rather than controlled braking.

Question 3

Which alcohol finding is enough to place a CMV driver out of service for 24 hours?

  1. A A BAC of 1.0% or higher
  2. B Any measured concentration or detected presence of alcohol
  3. C A BAC of 0.05% or higher
  4. D A BAC of 0.04% or higher

Correct answer: B – Any measured concentration or detected presence of alcohol

Federal motor-carrier rules prohibit a driver from being on duty or operating a CMV with any measured alcohol concentration or detected presence of alcohol. A driver who violates this rule must be placed out of service for 24 hours. A BAC of 0.04% or more while operating a CMV also carries CDL disqualification consequences, but that is a separate threshold.

Question 4

When should a commercial driver complete a pre-trip inspection?

  1. A At least once each week
  2. B Only at the beginning of a workweek
  3. C Only when the vehicle had problems on its last trip
  4. D Before driving the vehicle

Correct answer: D – Before driving the vehicle

Georgia’s CDL study guide explains that a pre-trip inspection helps identify defects that could cause a crash or breakdown. Before driving, the driver must be satisfied that the vehicle is in safe operating condition. The inspection should include safety-critical equipment and confirmation that the cargo is properly balanced and secured.

Question 5

What is the primary purpose of hazardous-material placards on a vehicle?

  1. A To warn others about the hazardous materials being carried
  2. B To improve the vehicle’s braking performance
  3. C To identify every oversized load
  4. D To display the motor carrier’s safety rating

Correct answer: A – To warn others about the hazardous materials being carried

Placards are exterior warning signs used to communicate hazardous-material risks. Their colors, symbols, and wording identify the cargo’s hazard class or division. This information helps other road users and emergency responders recognize the potential danger associated with the shipment.

Question 6

Which statement describes the safest general practice for backing a commercial vehicle?

  1. A Correct trailer drift by turning the top of the wheel away from the drift
  2. B Avoid backing whenever a forward maneuver is practical
  3. C Have a helper direct you primarily with shouted instructions
  4. D Choose backing over forward movement whenever possible

Correct answer: B – Avoid backing whenever a forward maneuver is practical

Georgia’s CDL study guide instructs drivers to avoid backing whenever possible and to park where they can pull forward when leaving. When backing is necessary, inspect the path, use both mirrors, move slowly, and use a helper when available. The driver and helper should agree on clear hand signals, including a stop signal.
