Sample Wyoming CDL Test Questions - General Knowledge

Question 1

Under similar conditions, doubling your speed makes your vehicle’s braking distance approximately how many times longer?

  1. A. 3 times
  2. B. 2 times
  3. C. 4 times
  4. D. 5 times

Correct answer: C. – 4 times

Doubling speed makes braking distance approximately four times longer under similar conditions. For example, doubling from 20 mph to 40 mph produces about four times the braking distance. This relationship concerns braking distance; total stopping distance also includes the distance traveled during perception and reaction time.

Question 2

If your commercial vehicle stops on the traveled portion or shoulder for a reason other than a necessary traffic stop, what should you do immediately?

  1. A. Activate the four-way hazard warning 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 hazard warning flashers

Federal motor carrier regulations require the vehicle’s hazard warning signal flashers to be activated immediately. Keep them operating until the required external warning devices are placed, then use the flashers again while retrieving those devices. The warning devices generally must be placed within 10 minutes, not 15 minutes.

Question 3

What is the main danger when wheels lock and skid during emergency braking?

  1. A. The steering-axle brakes automatically disconnect
  2. B. The vehicle will remain straight if more brake pressure is applied
  3. C. The transmission cannot be downshifted
  4. D. The driver loses directional control while the wheels are skidding

Correct answer: D. – The driver loses directional control while the wheels are skidding

A driver cannot control the vehicle’s direction effectively while its wheels are locked and skidding. Locked steering wheels eliminate steering control, while other locked wheels can cause a skid, jackknife, or spin. In a vehicle without ABS, release the brakes if the wheels lock, regain traction, and resume the proper emergency-braking technique.

Question 4

Properly adjusted outside convex mirrors on a school bus should show:

  1. A. The entire side of the bus up to the mirror mounts
  2. B. The front of the rear tires where they contact the ground
  3. C. At least one traffic lane on each side of the bus
  4. D. All of these areas

Correct answer: D. – All of these areas

The Wyoming CDL manual directs drivers to adjust the outside convex mirrors so all three areas are visible. These views help the driver monitor the bus’s sides, the ground near the rear wheels, and traffic in adjacent lanes. Convex mirrors provide a wider field of view, but objects appear smaller and farther away than they are.

Question 5

What must you do when you reach a STOP sign?

When approaching this sign, you are required to _____________.
  1. A. Slow down and continue if the intersection looks clear
  2. B. Stop only when another vehicle is approaching
  3. C. Come to a complete stop
  4. D. Continue after sounding the horn

Correct answer: C. – Come to a complete stop

Wyoming law requires a driver approaching a STOP sign to come to a complete stop. Stop at the marked stop line; if none exists, stop before entering the crosswalk. If there is neither a stop line nor a crosswalk, stop at the point nearest the intersecting roadway where you can view approaching traffic. Proceed only after yielding as required.

Question 6

Your CMV is disabled on an undivided highway with no nearby hill or curve. Where should you place three warning triangles?

  1. A. One within 10 feet on the traffic side, one about 100 feet ahead, and one about 100 feet behind
  2. B. At 10, 100, and 200 feet behind the vehicle
  3. C. At 100 feet ahead and at 100 and 200 feet behind
  4. D. At 100, 200, and 500 feet behind the vehicle

Correct answer: A. – One within 10 feet on the traffic side, one about 100 feet ahead, and one about 100 feet behind

On a two-way or undivided highway, federal rules require one warning device on the traffic side within 10 feet of the stopped CMV. Place the other two approximately 100 feet from the vehicle in opposite directions. This arrangement marks the vehicle while warning traffic approaching from both the front and rear.
