Sample Montana CDL Test Questions - General Knowledge

Question 1

In safe commercial driving, what does communicating your intentions involve?

  1. A Talking on a mobile phone
  2. B Applying the brakes repeatedly
  3. C Sounding the horn before every maneuver
  4. D Using signals to show other drivers what you plan to do

Correct answer: D – Using signals to show other drivers what you plan to do

Other drivers cannot know what you plan to do unless you communicate it. Use turn signals before turns and lane changes, and keep them operating for the appropriate part of the maneuver. Brake lights and four-way flashers can also warn traffic when you are slowing or traveling unusually slowly.

Question 2

What should you do when you see a yellow warning sign showing a car with wavy skid marks?

This sign warns drivers to _________________.
  1. A Reduce speed and avoid sudden braking or steering when the pavement is wet
  2. B Do not continue driving if rain is falling
  3. C Prepare for soft ground that may trap the vehicle
  4. D Expect the roadway to be equally slippery in all weather

Correct answer: A – Reduce speed and avoid sudden braking or steering when the pavement is wet

The Slippery When Wet sign warns that pavement is unusually slick when wet. Reduce speed and avoid hard braking or sudden changes in direction. Increasing the space between your vehicle and traffic ahead provides more room to respond on the reduced-traction surface.

Question 3

What does a solid yellow centerline on your side of the roadway generally prohibit?

  1. A Crossing the centerline to pass
  2. B Continuing in your present lane
  3. C Turning left into a driveway
  4. D Driving faster than 25 mph

Correct answer: A – Crossing the centerline to pass

In Montana, a solid yellow line on your side means you may not cross the centerline to pass. A solid yellow line may still be crossed as part of a lawful left turn when the movement can be made safely. Yellow centerlines separate traffic traveling in opposite directions.

Question 4

Which pair of items should be included when inspecting a commercial vehicle before a trip?

  1. A Cargo securement only
  2. B Cleanliness and operation of the vehicle’s lights only
  3. C Both cargo securement and the vehicle’s lights
  4. D Neither item

Correct answer: C – Both cargo securement and the vehicle’s lights

Montana’s CDL inspection guidance requires a truck driver to verify that cargo is balanced and secured before the trip. Lights must also be inspected for proper operation, and their lenses should be clean and undamaged. Both checks help identify conditions that must be corrected before the vehicle is driven.

Question 5

What minimum tread depth is required in the major grooves of a truck’s front tires?

  1. A 4/32 inch
  2. B 2/32 inch
  3. C 7/16 inch
  4. D 3/8 inch

Correct answer: A – 4/32 inch

Federal equipment rules require at least 4/32 inch of tread in a major groove on the front wheels of a bus, truck, or truck tractor. Measurements are not taken at tie bars, humps, or fillets. Tires in other positions generally require at least 2/32 inch.

Question 6

When dense fog severely reduces visibility, what is the preferred action when a safe facility is available?

  1. A Use high beams and continue driving
  2. B Stop on the roadway shoulder with only parking lights on
  3. C Pull into a rest area or truck stop until visibility improves
  4. D Continue at the posted speed limit

Correct answer: C – Pull into a rest area or truck stop until visibility improves

Montana CDL guidance advises avoiding travel in fog when possible and pulling into a rest area or truck stop until visibility improves. If driving must continue, slow before entering the fog and use low-beam headlights and fog lights. High beams reflect from the fog, and stopping along the roadside should be avoided unless absolutely necessary.
