Sample Louisiana CDL Test Questions - General Knowledge

Question 1

When scanning well ahead, which two categories deserve your main attention?

  1. A Traffic and roadway conditions
  2. B Only vehicles and traffic signals
  3. C Only disabled vehicles and debris
  4. D Only curves and pavement defects

Correct answer: A – Traffic and roadway conditions

Louisiana's CDL manual directs drivers to scan ahead for traffic and roadway conditions. Watch for vehicles entering, turning, changing lanes, or braking. Also identify curves, grades, work zones, surface hazards, and other conditions early enough to adjust speed or position smoothly.

Question 2

Containerized freight is most commonly associated with which type of transportation?

  1. A Transportation exempt from hazardous-material requirements
  2. B Transportation exempt from vehicle weight limits
  3. C Trips involving truck service and travel by rail, ship, or both
  4. D Transportation that does not require cargo securement

Correct answer: C – Trips involving truck service and travel by rail, ship, or both

Freight containers are generally used when cargo travels part of the journey by rail or ship, with trucks handling the beginning or end of the trip. A container must still be properly attached to its frame or secured on the trailer. Containerization does not cancel weight, securement, or hazardous-material requirements.

Question 3

If your commercial vehicle catches fire, should you pull into a service station for assistance?

  1. A True
  2. B False

Correct answer: B – False

In Louisiana, move a burning vehicle off the roadway and stop in an open area away from buildings, vegetation, vehicles, and other materials that could ignite. Do not enter a service station, where fuel may increase the danger. Notify emergency services and provide your location.

Question 4

To balance cargo from front to rear, how should the load be positioned?

  1. A Concentrated near the front
  2. B Concentrated near the rear
  3. C Centered and distributed across the appropriate axles
  4. D Placed entirely along one side

Correct answer: C – Centered and distributed across the appropriate axles

Cargo should be centered and distributed to maintain proper axle loading. Excessive steering-axle weight can make steering difficult and damage components. Weight placed too far rearward can leave the steering axle too light, while insufficient drive-axle weight can reduce traction.

Question 5

What is the purpose of controlled braking during an emergency stop?

  1. A To lock every wheel immediately
  2. B To replace the parking brake
  3. C To stop without using the service brakes
  4. D To keep the vehicle straight while retaining the ability to steer

Correct answer: D – To keep the vehicle straight while retaining the ability to steer

Controlled braking means applying the brakes as hard as possible without locking the wheels. The goal is to keep the vehicle traveling in a straight line while preserving the ability to steer if necessary. If the wheels lock or a large steering correction is needed, release the brakes and reapply them as soon as possible.

Question 6

After beginning a cargo trip, when must the load and its securement be rechecked?

  1. A Within 25 miles, then every 2 hours or 100 miles
  2. B Only before departure and after reaching the destination
  3. C Within 50 miles, then after a duty-status change or 3 hours or 150 miles, whichever occurs first
  4. D Once during each driving day

Correct answer: C – Within 50 miles, then after a duty-status change or 3 hours or 150 miles, whichever occurs first

Federal cargo-inspection rules require a recheck within the first 50 miles after beginning the trip. The driver must inspect again after each change of duty status or after driving three hours or 150 miles, whichever occurs first. Cargo and securement devices must be adjusted when necessary to keep the load secure.
