Sample Alabama CDL Test Questions - General Knowledge

Question 1

If there is not enough distance to stop before an obstacle, which emergency-driving principle is correct?

  1. A A steering maneuver can often avoid the obstacle more quickly than stopping
  2. B Stopping is always the safest response
  3. C Leaving the roadway is always worse than a collision
  4. D The driver should release the seat belt before impact

Correct answer: A – A steering maneuver can often avoid the obstacle more quickly than stopping

Stopping is not always the safest response when there is too little room to stop before a hazard. A driver may be able to steer around an obstacle more quickly. Quick steering must be handled carefully because top-heavy vehicles and tractors pulling multiple trailers have an increased risk of rolling over.

Question 2

What is the primary safety benefit of an antilock braking system?

  1. A It permits higher speeds and shorter following distances
  2. B It prevents every type of skid
  3. C It always reduces stopping distance
  4. D It helps prevent wheel lockup and maintain control during hard braking

Correct answer: D – It helps prevent wheel lockup and maintain control during hard braking

ABS monitors for potential wheel lockup and adjusts brake pressure to help maintain control during hard braking. It may or may not shorten stopping distance. Its main benefit is helping the driver retain steering control and avoid skids caused by overbraking, not permitting faster or more aggressive driving.

Question 3

Hazardous material is spilling from your vehicle. Which response follows the recommended emergency procedure?

  1. A Park the vehicle as soon as safety permits
  2. B Secure the area and keep others away
  3. C Remain at the scene and call for help or send someone for help
  4. D All of these actions

Correct answer: D – All of these actions

The Alabama CDL manual directs the driver to move a leaking vehicle no more than safety requires, park it, secure the area, and remain at the scene. Call for help or send someone else. Do not continue driving to find assistance, and keep other people away from the hazardous area.

Question 4

What problems can result when brakes become wet in heavy rain or deep standing water?

  1. A Wheel lockup
  2. B A trailer jackknife
  3. C Pulling to one side
  4. D All of these

Correct answer: D – All of these

Water can make brakes weak, uneven, or prone to grabbing. These conditions may reduce braking power, lock a wheel, or pull the vehicle to one side. If the vehicle is pulling a trailer, uneven or grabbing brakes may also contribute to a jackknife.

Question 5

At a railroad crossing, the lights are flashing, the gate is lowered, and a train is approaching. What must you do?

  1. A Accelerate and cross before the train arrives
  2. B Cross if the nearest track appears clear
  3. C Drive around the lowered gate
  4. D Stop and wait until the gate rises and the lights stop flashing

Correct answer: D – Stop and wait until the gate rises and the lights stop flashing

Alabama law requires a driver to stop when a crossing signal warns of an approaching train, a gate is lowered, or a train presents an immediate hazard. Remain stopped while the warning system is active. Proceed only after the gate rises, the lights stop flashing, and the crossing is safe.

Question 6

Your commercial vehicle is stopped on the highway shoulder at night because of a breakdown. What should you do immediately?

  1. A Activate the four-way emergency flashers
  2. B Wait up to 15 minutes before placing warning devices
  3. C Leave the left turn signal operating
  4. D Leave the high-beam headlights on

Correct answer: A – Activate the four-way emergency flashers

Federal rules require a stopped commercial vehicle on the traveled roadway or shoulder to use its hazard warning flashers immediately, except for a necessary traffic stop. The flashers remain on while required warning devices are being placed. Those devices generally must be set out as soon as possible and within 10 minutes, not 15 minutes.
