  1. A 10

  3. C 50
  4. D 100

Correct answer: C – 50

  1. A In a closed cargo compartment
  2. B Near the rear of the cargo area
  3. C In the driver’s cab or sleeper berth
  4. D In a properly secured cargo rack

Correct answer: C – In the driver’s cab or sleeper berth

Packages labeled POISON or POISON INHALATION HAZARD must not be loaded in the driver’s compartment or sleeper berth. They belong in an authorized cargo area and must be secured and handled according to the applicable loading rules. Additional restrictions apply when poisonous materials are transported with food intended for people or animals.

Question 3

When a cargo tank is filled with flammable liquid through an open filling hole, how long must the grounding connection be maintained?

  1. A Only while the filling hose is being attached
  2. B From before the filling hole is opened until after it is closed
  3. C Only during the final half of the filling operation
  4. D Until the vehicle leaves the loading facility

Correct answer: B – From before the filling hole is opened until after it is closed

California’s handbook directs drivers to ground a cargo tank before opening an open filling hole. The electrical bond must remain in place throughout filling and until after the filling hole has been closed. This procedure controls static-electricity hazards during open-hole loading of flammable liquid.

Question 4

You find HazMat leaking slowly from your vehicle at a rest area, and your phone and radio do not work. What should you do?

  2. B Unload the leaking cargo before leaving for help
  3. C Park, secure the area, remain there, and send someone else for help
  4. D Clean the visible residue and continue the trip

Correct answer: C – Park, secure the area, remain there, and send someone else for help

The California handbook directs the driver to park, secure the area, remain with the vehicle, and call for help when HazMat is leaking. If communication equipment does not work, send someone else. Do not continue driving merely to locate a telephone, because moving the vehicle may spread contamination or worsen the leak.

  4. D Protect the area and call for qualified help

Correct answer: D – Protect the area and call for qualified help

At a HazMat incident, the driver should keep people away, warn others of the danger, and call for help. Shipping papers and emergency response information should be available for responders. The vehicle should not be moved or the cargo handled when doing so would spread contamination or create additional danger.
