Tennessee CDL Permit Test - HazMat

If a shipping paper describes both hazardous and non-hazardous materials, the hazardous materials must be distinguished in one of three ways. They must be entered first on the shipping paper, highlighted in a contrasting color, or properly marked with an "X" in a column titled "HM."

While the manual includes all of the information required to pass the hazardous materials knowledge test, you should consider reading the manual as only the first step to learning about the topic. You can learn more by reading and understanding the federal and state rules about the transportation of hazardous materials, as well as by attending hazardous materials training courses.

In the event of a leak in a cargo of hazardous materials, do not continue to drive any longer than is necessary for safety. Continuing to drive would result in a larger area becoming contaminated. Instead, park the vehicle, secure the area, stay with the vehicle, and send someone to get help.

When hazardous materials placards are required, they must be placed on all four sides of the transporting vehicle.

Always turn the engine off before refueling a vehicle carrying hazardous materials. Someone must always be at the nozzle controlling the fuel flow.

When a shipping paper includes both hazardous and non-hazardous materials, one acceptable method of identifying the hazardous items is to highlight them in a contrasting color.
