Sample West Virginia CDL Test Questions - General Knowledge

Question 1

A curve warning sign with a 40 mph advisory plaque indicates that:

This sign warns drivers to _______________.
  1. A Vehicles traveling under 40 mph must remain in the right lane
  2. B Drivers are required to maintain at least 40 mph
  3. C 40 mph is the recommended operating speed for the curve under favorable conditions
  4. D Drivers should travel faster than 40 mph through the curve

Correct answer: C – 40 mph is the recommended operating speed for the curve under favorable conditions

An advisory speed plaque displays the recommended operating speed for the condition shown on the warning sign. Here, 40 mph is the advised speed for the curve under free-flowing conditions. Weather, road surface, traffic, vehicle characteristics, or cargo may require a commercial driver to travel more slowly.

Question 2

What must a driver do when approaching this sign?

When approaching this sign _______________.
  1. A Watch only for children entering the roadway
  2. B Enter the intersection quickly
  3. C Slow down and yield to traffic with the right-of-way, stopping if necessary
  4. D Proceed because other traffic must yield

Correct answer: C – Slow down and yield to traffic with the right-of-way, stopping if necessary

A Yield sign requires the driver to slow to a reasonable speed and give the right-of-way to conflicting traffic. Stop when necessary for safety before entering the intersection or roadway. The sign does not give the approaching driver priority over other traffic.

Question 3

Unless a listed crossing exception applies, which commercial vehicles must stop before railroad tracks?

  1. A Every commercial motor vehicle
  2. B Buses transporting passengers and specified vehicles carrying hazardous materials
  3. C Commercial vehicles traveling at night
  4. D Only vehicles approaching an unmarked crossing

Correct answer: B – Buses transporting passengers and specified vehicles carrying hazardous materials

West Virginia law requires buses transporting passengers and specified commercial vehicles carrying hazardous materials to stop at railroad grade crossings, subject to listed exceptions. The stop must be made within 50 feet but not closer than 15 feet from the tracks. Other CMV drivers must slow sufficiently, exercise due caution, and confirm that the tracks are clear.

Question 4

Which factors should guide your choice of speed on a long, steep downgrade?

  1. A Perception distance, reaction time, and traffic speed
  2. B Vehicle length, mirror size, and engine horsepower
  3. C Vehicle and cargo weight, grade length and steepness, road conditions, and weather
  4. D Posted speed, stopping distance, and the number of traffic lanes

Correct answer: C – Vehicle and cargo weight, grade length and steepness, road conditions, and weather

Gravity causes a vehicle to gain speed on a downgrade. Select and maintain a speed appropriate for the total weight of the vehicle and cargo, the grade’s length and steepness, road conditions, and weather. Enter the downgrade in a proper low gear and use engine braking as the principal method of controlling speed.

Question 5

Which item is not included in the general CMV emergency-equipment checklist?

  1. A A properly charged and rated fire extinguisher
  2. B Spare electrical fuses when the vehicle does not use circuit breakers
  3. C A first-aid kit
  4. D Warning devices for a stopped vehicle

Correct answer: C – A first-aid kit

The West Virginia CDL inspection checklist includes a properly charged fire extinguisher, spare electrical fuses unless circuit breakers are used, and approved warning devices. A first-aid kit is not one of the three general items on that checklist. Additional equipment may be required for a specialized vehicle or operation.

Question 6

What are the two functions of a combination vehicle’s emergency air line?

  1. A It supplies air to the trailer tanks
  2. B It controls the trailer emergency brakes
  3. C It performs both functions
  4. D It applies only the tractor’s service brakes

Correct answer: C – It performs both functions

The emergency or supply line carries air to the trailer air tanks and controls the trailer’s emergency brakes. A loss of pressure in this line causes the trailer emergency brakes to apply. The pressure loss also causes the tractor protection valve to close, helping prevent the tractor’s air supply from escaping.
