Sample Wyoming Combination Test Questions

Question 1

Compared with empty rigs, fully loaded rigs are how many times more likely to roll over in a crash?

  1. A. Two times
  2. B. Three times
  3. C. Five times
  4. D. Ten times

Correct answer: D. – Ten times

The CDL manual states that fully loaded rigs are ten times more likely to roll over in a crash than empty rigs. Adding cargo can raise the vehicle’s center of gravity, making the rig easier to overturn. Keeping cargo low and centered and reducing speed for turns helps control this risk.

Question 2

If locked trailer wheels cause the trailer to begin skidding, what should you do?

  1. A. Accelerate to pull the trailer straight
  2. B. Steer sharply away from the skid
  3. C. Apply the trailer hand control harder
  4. D. Release the brakes to restore traction

Correct answer: D. – Release the brakes to restore traction

Wyoming’s CDL manual directs the driver to release the brakes when a trailer skid develops. This allows the trailer wheels to regain traction and begin following the tractor again. Do not apply the trailer hand control to straighten the rig, because additional trailer braking can worsen the skid.

Question 3

Which action checks the security of a newly coupled tractor-semitrailer?

  1. A. Accelerate quickly with all brakes released
  2. B. Make a tight turn and watch the trailer
  3. C. Gently pull forward while the trailer brakes remain locked
  4. D. Check only the trailer position in the mirrors

Correct answer: C. – Gently pull forward while the trailer brakes remain locked

Raise the trailer landing gear slightly off the ground and keep the trailer brakes locked. Gently pull the tractor forward to confirm that the trailer is locked onto the fifth wheel. This physical test does not replace the required visual inspection of the fifth-wheel jaws, locking lever, safety latch, and fifth-wheel plates.

Question 4

Poorly balanced cargo can make a combination vehicle unsafe to handle.

  1. A. True
  2. B. False

Correct answer: A. – True

Poor weight balance can interfere with safe vehicle handling. Excessive steering-axle weight can make steering difficult, while too little steering-axle weight can reduce steering control. Too little weight on the drive axles can also produce poor traction, and a high center of gravity increases rollover risk.

Question 5

Which feature normally identifies a trailer equipped with an antilock braking system?

  1. A. A red lamp on the trailer’s right side
  2. B. A label on each spring-brake chamber
  3. C. A yellow ABS malfunction lamp on the trailer’s left side
  4. D. A blue lamp beside the emergency air line

Correct answer: C. – A yellow ABS malfunction lamp on the trailer’s left side

The Wyoming CDL manual identifies a trailer’s yellow ABS malfunction lamp on the left side, at either the front or rear corner. If an older towed unit does not have an obvious lamp, determining whether it has ABS may require looking underneath for the electronic control unit and wheel-speed-sensor wiring.

Question 6

Why should the glad-hand couplers and seals be inspected and cleaned before connection?

  1. A. To improve fuel efficiency
  2. B. To reduce trailer-tire wear
  3. C. To make the fifth wheel lock faster
  4. D. To help prevent air from escaping

Correct answer: D. – To help prevent air from escaping

Glad hands connect the tractor’s service and emergency air lines to the trailer. Their rubber seals prevent air from escaping, so the couplers and seals should be clean and free of damage before connection. Dirt, cracks, or damaged seals can prevent a proper connection and allow air leakage.
