Sample Tennessee CDL Test Questions - General Knowledge

Question 1

Which statement correctly distinguishes road rage from aggressive driving?

  1. A. The two terms always describe the same conduct
  2. B. Aggressive driving never involves rude language
  3. C. Road rage includes an intent to harm someone or physically attack a driver or vehicle
  4. D. Road rage exists only when a weapon is used

Correct answer: C. – Road rage includes an intent to harm someone or physically attack a driver or vehicle

Aggressive driving involves operating a vehicle in a selfish, forceful, or unsafe manner without regard for others’ rights or safety. Road rage goes further by involving an intent to harm others or physically assault a driver or the driver’s vehicle. The use of a weapon is not required for conduct to fit that description.

Question 2

In Tennessee’s alley-dock skills exercise, which action is incorrect?

  1. A. Use sight-side backing into the alley
  2. B. Finish straight with the rear of the vehicle within 3 feet of the rear boundary
  3. C. Keep backing until the vehicle touches the rear boundary

Correct answer: C. – Keep backing until the vehicle touches the rear boundary

The alley-dock exercise requires sight-side backing into the marked alley. At completion, the vehicle must be straight, and its rear must be within three feet of the back of the alley. The maneuver must be completed without touching the boundary lines or cones, so backing until contact is incorrect.

Question 3

Which factors should be considered when selecting a safe speed on a mountain grade?

  1. A. The total weight of the vehicle and cargo
  2. B. The length and steepness of the grade
  3. C. Road and weather conditions
  4. D. All of these factors

Correct answer: D. – All of these factors

A safe mountain-driving speed must account for the vehicle’s total weight, the grade’s length and steepness, road conditions, and weather. The driver must also obey posted speed limits and maximum-safe-speed signs. On a downgrade, the selected speed must be low enough for engine braking and proper braking techniques to control the vehicle.

Question 4

What is perception distance?

  1. A. The distance traveled while moving your foot from the accelerator to the brake
  2. B. The distance traveled from seeing a hazard until the brain recognizes it
  3. C. The distance traveled after the brakes are applied
  4. D. The full distance traveled before the vehicle stops

Correct answer: B. – The distance traveled from seeing a hazard until the brain recognizes it

The Tennessee CDL manual defines perception distance as the distance traveled from the moment the driver sees a hazard until the brain recognizes it. It is the first part of total stopping distance. Reaction distance begins after recognition, while braking distance begins when the brakes are applied.

Question 5

In which situation might operating at the legal maximum weight still be unsafe?

  1. A. Driving in mountains or bad weather
  2. B. Carrying freight in a sealed container
  3. C. Operating on a straight, dry, level roadway
  4. D. Hauling non-hazardous cargo

Correct answer: A. – Driving in mountains or bad weather

The CDL manual warns that operating at legal maximum weights may be unsafe in mountains or bad weather. Heavy loads can reduce speed on upgrades and contribute to excessive speed on downgrades. Increased weight also affects braking and stopping distance, making current terrain and weather important even when the load is legally permitted.

Question 6

How should you plan to park a commercial vehicle when possible?

  1. A. Park where the inspection can be skipped before departure
  2. B. Park so you can pull forward when leaving
  3. C. Park where backing will be limited to exactly 10 feet
  4. D. Park as close as possible to a highway entrance ramp

Correct answer: B. – Park so you can pull forward when leaving

The Tennessee CDL manual advises avoiding backing whenever possible because the driver cannot see everything behind a commercial vehicle. When parking, try to position the vehicle so that you can leave by pulling forward. If backing cannot be avoided, inspect the path, use both mirrors, move slowly, and use a helper when available.
