Sample Montana CDL Test Questions - General Knowledge

Question 1

What is identified as the leading cause of injuries and deaths in roadway work zones?

  1. A Speeding traffic
  2. B Wet pavement
  3. C Brake defects
  4. D Limited nighttime visibility

Correct answer: A – Speeding traffic

Speeding traffic is identified as the number one cause of injury and death in roadway work zones. Drivers must obey the posted limit and monitor their speed throughout the work area. Additional speed reduction may be needed for poor weather, hazardous road conditions, or workers close to the roadway.

Question 2

Which vehicle fire may require large quantities of water for cooling?

  1. A A burning tire
  2. B A gasoline fire
  3. C An energized electrical fire
  4. D An unidentified hazardous-materials fire

Correct answer: A – A burning tire

A burning tire must be cooled thoroughly, and large amounts of water may be necessary. Water can spread a gasoline fire and create a shock hazard when used on energized electrical equipment. If you do not know the correct extinguishing agent, especially with hazardous materials, wait for trained firefighters.

Question 3

In which situation is evacuation of a school bus mandatory?

  1. A The bus is burning or threatened by fire
  2. B The bus is stalled on or next to a railroad-highway crossing
  3. C A collision is about to occur
  4. D Any of these situations

Correct answer: D – Any of these situations

The driver must evacuate when fire exists or is threatened, when the bus is stalled on or adjacent to a railroad-highway crossing, or when a collision is imminent. These are mandatory evacuation conditions in Montana’s school-bus guidance. A hazardous-materials spill requiring rapid evacuation is another listed condition.

Question 4

What is your primary means of monitoring traffic beside and behind a commercial vehicle?

  1. A A helper
  2. B The mirrors
  3. C The turn signals
  4. D The horn

Correct answer: B – The mirrors

Regular mirror checks help you track vehicles beside and behind your commercial vehicle. Mirrors should be checked more frequently during lane changes, turns, merges, and other tight maneuvers. They also help monitor parts of the vehicle and cargo, although drivers must remember that mirrors do not eliminate every blind spot.

Question 5

What handling problem can result from placing excessive weight on the steering axle?

  1. A Steering becomes difficult
  2. B Steering becomes unusually light
  3. C The brakes apply automatically
  4. D Braking effort is eliminated

Correct answer: A – Steering becomes difficult

Poor weight distribution can make a commercial vehicle unsafe to handle. Too much weight on the steering axle can cause hard steering and may damage the axle or tires. Too little weight on that axle creates a different hazard because the front tires may not have enough traction to steer safely.

Question 6

What does an orange highway sign normally indicate?

  1. A A construction or maintenance warning
  2. B A general permanent warning
  3. C Route or destination information
  4. D A required stop

Correct answer: A – A construction or maintenance warning

Orange signs provide warnings and guidance in temporary traffic-control areas, including construction, utility, and road-maintenance operations. Drivers should watch for changing lanes, workers, equipment, reduced speeds, and altered traffic patterns. Yellow is ordinarily used for general warning signs outside these temporary work areas.
