  1. A. Fuel is available nearby
  2. B. Road construction is ahead
  3. C. A temporary detour begins here
  4. D. Traffic must come to a full stop

Correct answer: A. – Fuel is available nearby

Question 4

Under otherwise similar conditions, which vehicle may require the greatest stopping distance?

  1. A. A fully loaded truck
  2. B. An empty truck
  3. C. A partially loaded truck
  4. D. They always stop in the same distance

Correct answer: B. – An empty truck

An empty truck can require more stopping distance because it has less traction. Strong brakes and stiff suspension can make the wheels lock more readily when little weight is carried. Wheel lockup may cause skidding and make smooth, controlled braking more difficult.

Question 5

How many numbered hazard classes are used for hazardous materials?

  1. A. 3

Hazardous materials are divided into nine numbered classes.

Several classes are further divided into divisions.

  1. A. Leave before traffic backs up
  2. B. Remove your personal belongings
  3. C. Protect the area from another crash
  4. D. Debate who caused the crash

Correct answer: C. – Protect the area from another crash

The New Mexico CDL manual lists protecting the area as the first basic crash-scene step, followed by notifying authorities and caring for injured people. Turn on the flashers and place reflective triangles where approaching drivers can see them in time. If the involved vehicle can be moved safely, getting it off the traveled roadway can help prevent another collision.
