Sample Wyoming CDL Test Questions - General Knowledge

Question 1

Federal hazardous-materials regulations divide hazardous materials into how many numbered classes?

  1. A. 3
  2. B. 6
  3. C. 9
  4. D. 12

Correct answer: C. – 9

Federal hazardous-materials regulations establish nine numbered hazard classes. They cover explosives, gases, flammable liquids, several types of reactive solids, oxidizers and organic peroxides, toxic and infectious substances, radioactive materials, corrosives, and miscellaneous hazardous materials. Some classes are divided into more specific divisions.

Question 2

At a triangular red-and-white YIELD sign, which action is required?

When approaching this sign _______________.
  1. A. Watch only for children entering the road
  2. B. Enter the intersection quickly before traffic arrives
  3. C. Give way to traffic that is close enough to present an immediate hazard
  4. D. Proceed because intersecting traffic must yield

Correct answer: C. – Give way to traffic that is close enough to present an immediate hazard

Wyoming law requires the approaching driver to slow to a reasonable speed and yield to vehicles in the intersection or approaching closely enough to be an immediate hazard. Stop if necessary for safety. The sign does not require an automatic stop when the intersection is clear, but it never gives priority over conflicting traffic.

Question 3

What two broad categories should a commercial driver continually scan for ahead?

  1. A. Traffic and road conditions
  2. B. Vehicles and traffic lights only
  3. C. Disabled vehicles and roadside obstacles only
  4. D. Curves and potholes only

Correct answer: A. – Traffic and road conditions

Look ahead for traffic entering, turning, changing lanes, braking, or otherwise affecting your path. Also watch road conditions such as curves, hills, signs, signals, work zones, and surface hazards. Detecting these conditions early gives you time to change speed or position without making a sudden maneuver.

Question 4

What functions does the trailer emergency air line perform?

  1. A. It supplies air to the trailer air tanks
  2. B. It controls the trailer emergency brakes
  3. C. It performs both functions
  4. D. It performs neither function

Correct answer: C. – It performs both functions

The emergency line, also called the supply line, has two functions. It carries air to the trailer’s air tanks and controls the trailer emergency brakes. A major pressure loss in this line causes the tractor-protection system to close and the trailer emergency brakes to apply.

Question 5

When selecting a place to park, you should arrange the vehicle so that you can:

  1. A. Skip the next vehicle inspection
  2. B. Leave the parking space by moving forward
  3. C. Limit backing to exactly 10 feet
  4. D. Park as close as possible to an entrance ramp

Correct answer: B. – Leave the parking space by moving forward

Backing is dangerous because the driver cannot see everything behind a commercial vehicle. When parking, choose a position that allows you to pull forward when leaving whenever possible. This reduces exposure to backing hazards, although the driver must still check the path before moving.

Question 6

How far ahead should a commercial driver generally scan while driving?

  1. A. 1 to 2 seconds
  2. B. 5 to 8 seconds
  3. C. 12 to 15 seconds
  4. D. 18 to 21 seconds

Correct answer: C. – 12 to 15 seconds

Most good drivers look at least 12 to 15 seconds ahead, measured by the distance the vehicle will travel during that time. At lower speeds, this is approximately one city block; at highway speeds, it is about one-quarter mile. Continue shifting your attention between near and distant conditions rather than staring at one point.
