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.
The shipper of hazardous materials is responsible for packaging, marking, and labeling the materials properly. It is a good idea for the driver to ensure the materials are properly labeled.

Radiation will surround each package of radioactive materials and pass through to all nearby packages. The number of packages that can be loaded together is controlled.

If a shipping paper includes information about both hazardous and non-hazardous materials, the hazardous items must be clearly identified on the paper. They may be entered first, highlighted in a contrasting color, or identified with an "X" placed before the shipping description.

Many hazardous materials classified as poisonous are also flammable.
A vehicle that lacks the proper placards for any hazardous materials on board may not be driven, except as necessary to protect life and property in an emergency.
