Sample Massachusetts CDL Test Questions - General Knowledge

Question 1

Backing a school bus is generally an encouraged maneuver.

  1. A TRUE
  2. B FALSE

Correct answer: B – FALSE

The Massachusetts CDL manual strongly discourages backing a school bus. A driver should back only when there is no other safe way to move the bus and should never back while students are outside the bus. When backing is unavoidable, use a reliable lookout and follow the prescribed safety procedures.

Question 2

When scanning the roadway ahead, which two broad types of conditions should receive your attention?

  1. A Traffic activity and road conditions
  2. B Only vehicles and traffic signals
  3. C Only disabled vehicles and roadway debris
  4. D Only curves and potholes

Correct answer: A – Traffic activity and road conditions

Look ahead for traffic entering the highway, moving into your lane, turning, or slowing. Also watch road conditions such as hills, curves, work zones, and other features that may require a speed or lane adjustment. Seeing these conditions early gives you more time to respond smoothly.

Question 3

When providing basic assistance to an injured person at a crash scene, what should you do?

  1. A Move the person only when fire or passing traffic creates a greater danger
  2. B Apply direct pressure to control heavy bleeding
  3. C Keep the injured person warm
  4. D All of the above

Correct answer: D – All of the above

Do not move a severely injured person unless fire or passing traffic makes movement necessary. Heavy bleeding should be controlled by applying direct pressure to the wound, and the injured person should be kept warm. If a qualified person is already providing care, stay out of the way unless asked to assist.

Question 4

After a period of dry weather, when is the roadway usually most slippery?

  1. A When rain first begins
  2. B Only during a heavy downpour
  3. C After rain has continued for several hours
  4. D Immediately after the rain stops

Correct answer: A – When rain first begins

Roads can become especially slippery when rain first begins after a dry period. Water mixes with oil and other material left on the road, creating a slick surface. This condition may last for only a few minutes or for more than an hour, depending on the roadway and rainfall.

Question 5

Before crossing the roadway in front of a school bus, where should students stop?

  1. A At least 10 feet in front of the right-front corner of the bus
  2. B At least 10 feet in front of the left-front corner of the bus
  3. C Directly behind the right-rear bumper
  4. D Directly behind the left-rear bumper

Correct answer: A – At least 10 feet in front of the right-front corner of the bus

The Massachusetts CDL manual directs students crossing in front of the bus to move at least 10 feet ahead of its right-front corner. They should stop at the edge of the roadway and wait for the driver’s signal before crossing. The driver must be able to see the students throughout the procedure.

Question 6

Which two situations call for selecting a lower gear before the maneuver begins?

  1. A Before stopping and while leaving a curve
  2. B Before starting from a stop and while climbing a hill
  3. C Before shutting off the engine and leaving the cab
  4. D Before starting down a hill and before entering a curve

Correct answer: D – Before starting down a hill and before entering a curve

Select a lower gear before starting down a hill to help control speed without overusing the brakes. You should also slow down and shift to the proper gear before entering a curve. Shifting while in the curve can reduce stability and interfere with maintaining safe control.
