CDL Hazardous Materials (Hazmat) Practice Test 2

Question 1

Where must the identification number of a hazardous material appear?

Accepted Answer

The package and the shipping paper

Answer

The identification number (UN/NA number) for hazardous materials must appear in two essential locations: on the hazardous material package itself (typically near the proper shipping name or on the label) and on the shipping paper. This dual placement ensures that the material can be identified both physically and through documentation, which is vital for safety, emergency response, and regulatory compliance.

Question 2

What is the shipper's certification?

Accepted Answer

The shipper certifies that the shipment has been prepared according to the applicable rules

Answer

The shipper's certification is a legally binding statement on the shipping paper, signed by the shipper. It attests that the hazardous material has been properly classified, described, packaged, marked, and labeled according to all applicable hazardous materials regulations. This certification is crucial as it confirms the shipper's compliance and transfers responsibility to the carrier for accepting a compliant shipment.

Question 3

You are asked to transport a package that is properly marked and has a signed shipper's certification, but you notice the package is leaking. You should

Accepted Answer

Answer

A driver must always refuse to transport any hazardous material shipment that is leaking, even if it is otherwise properly marked and certified. A leaking package indicates a failure in containment and poses an immediate safety risk to the driver, other road users, and the environment. Accepting such a shipment would violate safety regulations and endanger lives.

Question 4

When approaching a railroad crossing at which you are required to stop, where should you stop?

Accepted Answer

15 to 50 feet before the nearest rail

Answer

Federal regulations require commercial vehicles, including buses, to stop at railroad crossings within a specific distance. The correct stopping zone is between 15 and 50 feet from the nearest rail. This distance allows the driver a clear view of the tracks in both directions to check for trains, while ensuring the vehicle is far enough away to avoid being struck.

Question 5

Accepted Answer

All of the above

Answer

Federal regulations mandate that a bus must stop at all railroad crossings under several conditions, including when carrying passengers, having an Inhalation Hazard placard, or transporting an empty used hazardous materials cargo tank. These specific circumstances indicate a higher risk, requiring the driver to stop, look, and listen carefully before proceeding to ensure maximum safety.
