Sample New Hampshire CDL Test Questions - General Knowledge

Question 1

When cargo is stacked, the heavier pieces should generally be placed below the lighter pieces.

  1. A TRUE
  2. B FALSE

Correct answer: A – TRUE

Heavy cargo placed high in a vehicle raises its center of gravity and increases the chance of a rollover, particularly during curves or sudden steering maneuvers. The safer arrangement is to distribute the load as low as possible, with heavier pieces beneath lighter pieces. The load must also be properly balanced and secured against movement.

Question 2

Which driving errors can result from alcohol impairment?

  1. A Delayed reactions to hazards
  2. B Driving too fast, too slowly, or in the wrong lane
  3. C Running over a curb or weaving
  4. D All of these are possible

Correct answer: D – All of these are possible

Alcohol affects judgment, vision, coordination, and reaction time. The resulting driving errors can include responding too slowly to hazards, choosing an improper speed, entering the wrong lane, striking a curb, and weaving. These effects increase crash risk even before a driver appears obviously intoxicated.

Question 3

Subject to the applicable hazardous-material requirements, which items may be transported on a passenger-carrying bus?

  1. A Small-arms ammunition
  2. B Emergency shipments of drugs
  3. C Emergency hospital supplies
  4. D All of these items

Correct answer: D – All of these items

Federal rules identify small-arms ammunition and emergency shipments of drugs, chemicals, and hospital supplies as exceptions to the general restrictions on hazardous materials aboard passenger-carrying vehicles. These exceptions do not eliminate other applicable packaging, handling, or transportation requirements. The carrier must confirm that the particular shipment is authorized before accepting it.

Question 4

How far ahead should a commercial driver generally scan while driving?

  1. A 2 to 5 seconds
  2. B 5 to 10 seconds
  3. C 12 to 15 seconds
  4. D 15 to 25 seconds

Correct answer: C – 12 to 15 seconds

The New Hampshire CDL manual recommends looking at least 12 to 15 seconds ahead—the distance the vehicle will cover during that time. This is approximately one block at lower speeds and about one-quarter mile at highway speeds. Drivers should continue shifting their attention between distant conditions and hazards that are closer to the vehicle.

Question 5

If reflective triangles are used as the required warning devices, how many must a commercial power unit carry?

  1. A 2
  2. B 4
  3. C 1
  4. D 3

Correct answer: D – 3

Federal equipment rules require three bidirectional emergency reflective triangles when triangles are selected as the required warning devices. An alternative equipment option is at least six fusees, except where restrictions prohibit flame-producing devices. Other warning devices may be carried in addition to the required equipment but cannot replace it.

Question 6

Properly adjusted mirrors eliminate every blind spot around a school bus.

  1. A TRUE
  2. B FALSE

Correct answer: B – FALSE

The New Hampshire CDL manual identifies blind spots immediately below and in front of the outside flat mirrors and directly behind the rear bumper. The rear blind spot can extend a considerable distance depending on the bus’s dimensions. Proper mirror adjustment provides the maximum viewing area, but it does not eliminate every blind spot or danger zone.
