Included in these regulations is a complete glossary of terms. It is essential for you to have an up-to-date copy of the complete regulations. Due to the constantly changing nature of government regulations, it is impossible to guarantee absolute accuracy of the materials in this section. Whether or not a material is considered hazardous is based on its characteristics and the shipper’s decision on whether or not the material meets a definition of a HazMat in the regulations.

The Hazardous Materials Table in the regulations contains a list of these items. The Hazardous Materials Regulations (HMR) and common references are found in CFR, Title 49, Parts 171-180. The state requirements are strictly enforced. Text preceded by “California” refers to state (nonfederal) requirements which also apply when driving in California. Your CDL tests will be based on your knowledge of federal transportation requirements. CVC §15278(a)(4) requires an “H” endorsement for those who drive a vehicle requiring placards. This includes vehicles carrying HazMat and/or wastes and vehicles which have not been purged of their hazardous cargo. To ensure public safety, DMV examiners will not conduct commercial skills tests in vehicles displaying vehicle placards per CVC §27903. Because of the risks involved and the potential consequences these risks impose, all levels of government regulate the handling of HazMat. HazMat include explosives, various types of gas, solids, flammable and combustible liquid, and other materials. The term often is shortened to HazMat, which you may see on road signs or to HM in government regulations.

HazMat are products that pose a risk to health, safety, and property during transportation. This section is designed to assist you in understanding your role and responsibilities in hauling HazMat.
