Sample Massachusetts CDL Test Questions - General Knowledge

Question 1

As blood alcohol concentration (BAC) rises, what happens to a person's ability to drive safely?

  1. A Alcohol affects fewer brain functions
  2. B The person becomes reliably aware of the impairment
  3. C Impairment increases, making the person more dangerous behind the wheel
  4. D The body eliminates alcohol more quickly

Correct answer: C – Impairment increases, making the person more dangerous behind the wheel

The Massachusetts CDL manual explains that alcohol affects more of the brain as BAC increases. Judgment and self-control are affected, followed by greater problems with vision, coordination, and muscle control. These effects increase the likelihood of serious driving errors and crashes.

Question 2

What is the safest compliant way to handle a necessary phone communication while operating a CMV?

  1. A Send texts only while traveling below 35 mph
  2. B Use a nearby hands-free device only if necessary, and pull off safely before communicating when practical
  3. C Hold the phone in your left hand to keep your right hand near the controls
  4. D Use a hand-held phone while stopped at a red light

Correct answer: B – Use a nearby hands-free device only if necessary, and pull off safely before communicating when practical

Federal rules prohibit texting and using a hand-held mobile telephone while driving a CMV, including while temporarily stopped in traffic. Massachusetts law also prohibits holding a mobile electronic device and generally requires hands-free operation. When practical, move off the highway and stop where the vehicle can safely remain stationary before communicating.

Question 3

Which description best defines a driving hazard?

  1. A Any roadway condition or road user that presents a possible danger
  2. B Only an object that completely blocks a travel lane
  3. C Only a mechanical problem involving your vehicle
  4. D Any situation that has already caused a collision

Correct answer: A – Any roadway condition or road user that presents a possible danger

A hazard can be a road condition or another road user, including a driver, bicyclist, or pedestrian, that presents a possible danger. Recognizing a hazard before it becomes an emergency provides more time to slow down, check surrounding traffic, or take another safe action.

Question 4

After starting the engine, which gauge should begin rising gradually toward its normal operating range?

  1. A The oil-pressure gauge after several minutes
  2. B The coolant-temperature gauge
  3. C The air-pressure gauge only after the vehicle begins moving
  4. D The voltmeter until it falls below its normal range

Correct answer: B – The coolant-temperature gauge

The coolant-temperature gauge should begin a gradual rise toward the normal operating range as the engine warms. Oil pressure should reach normal within seconds after startup. In an air-brake vehicle, air pressure should build from 50 to 90 psi within three minutes, subject to the vehicle’s requirements.

Which pair is identified as a cause of tire fires?

  1. A Highway speed and normal braking
  2. B Overinflation and gradual turns
  3. C Vehicle weight and rough pavement
  4. D Underinflated tires and dual tires that touch

Correct answer: D – Underinflated tires and dual tires that touch

The CDL manual specifically identifies underinflated tires and dual tires that touch as causes of tire fires. Drivers should inspect tires for proper inflation and check the tires, wheels, and truck body for signs of heat during a trip. These checks can reveal a developing problem before a fire occurs.

  1. A The power unit and empty trailer only

  4. D The driver, passengers, and cargo only

Correct answer: C – The power unit, trailer or trailers, and cargo

Gross combination weight is the total weight of the powered unit, the trailer or trailers, and the cargo. It refers to the combination’s actual weight. Gross combination weight rating, or GCWR, is a separate term describing the applicable rated weight of the combination.
