Sample Louisiana CDL Test Questions - General Knowledge

Question 1

How can an underloaded front axle affect vehicle control?

  1. A It makes the steering hard because of excessive axle weight
  2. B It can make the steering axle too light to steer safely
  3. C It always causes the rear of the vehicle to fishtail
  4. D It immediately damages the shock absorbers

Correct answer: B – It can make the steering axle too light to steer safely

Shifting too much cargo weight toward the rear can leave the front axle underloaded. The steering tires may then lack enough weight and traction to steer safely. By contrast, excessive weight on the steering axle can cause hard steering and damage the axle or tires.

Question 2

A long vehicle needs extra room to turn right from one two-lane street onto another. How should the turn be made?

  1. A Swing left into the opposing lane before beginning the right turn
  2. B Begin from the right, keeping the rear close to the curb, and turn wide only while completing the turn
  3. C Move fully into the left lane and turn right from there
  4. D Approach the corner diagonally across both lanes

Correct answer: B – Begin from the right, keeping the rear close to the curb, and turn wide only while completing the turn

Louisiana's CDL manual instructs drivers to make any needed wide movement while completing the right turn, not before starting it. Keep the rear of the vehicle close to the curb as long as practical. An initial swing to the left can mislead a following driver into attempting to pass on the right.

Question 3

How should you normally brake a commercial vehicle equipped with antilock brakes?

  1. A Always use less pedal pressure than with conventional brakes
  2. B Use normal braking procedures and only the force needed to stop safely
  3. C Apply maximum pressure during every stop
  4. D Release the accelerator and allow ABS to apply the brakes

Correct answer: B – Use normal braking procedures and only the force needed to stop safely

Brake normally in an ABS-equipped vehicle, using only the force needed to stop safely and maintain control. ABS helps prevent wheel lockup, but it does not apply the brakes when the accelerator is released. A straight truck or combination with working ABS on all axles may receive full brake application during an emergency stop.

Question 4

What happens when a straight vehicle enters a front-wheel skid?

  1. A It immediately slides sideways and spins
  2. B It slides sideways but cannot spin
  3. C It travels straight until the steering wheel is turned
  4. D It tends to continue straight even when the steering wheel is turned

Correct answer: D – It tends to continue straight even when the steering wheel is turned

During a front-wheel skid, the front end tends to continue in a straight line regardless of steering-wheel movement. On a very slippery surface, the vehicle may be unable to follow a curve. To recover, stop turning or braking so hard and allow the vehicle to slow without continuing the skid.

Question 5

What is the term for a long vehicle's rear wheels following a different, more inside path than its front wheels during a turn?

  1. A Jackknifing
  2. B Sidetracking
  3. C Off-tracking
  4. D Fishtailing

Correct answer: C – Off-tracking

Off-tracking occurs because the rear wheels follow a different path from the front wheels around a corner. Longer vehicles off-track more, and a trailer's rear wheels may track farther inside than the powered unit's rear wheels. Drivers must allow enough turning space to keep the rear wheels clear of curbs and other hazards.

Question 6

Which listed vehicle fire may require a large quantity of water for cooling?

  1. A A tire fire
  2. B A gasoline fire
  3. C A diesel-fuel fire
  4. D An electrical fire

Correct answer: A – A tire fire

A burning tire must be cooled, and a large amount of water may be necessary. Water should not be used on an electrical fire because of the shock hazard or on a gasoline fire because it can spread the flames. Flammable-liquid fires require an extinguisher rated for that class of fire.
