Summary

Defines key words used in these rules. A "commercial motor vehicle" is a self‑propelled or towed highway vehicle used in interstate commerce to move people or goods and that meets any of four tests: weight of at least 10,001 pounds; carries more than 8 passengers (including the driver) for pay; carries more than 15 passengers (including the driver) when not for pay; or carries hazardous material that must be placarded under section 5103. An "employee" includes drivers (even independent contractors), mechanics, freight handlers, or others (not employers) who directly affect commercial motor vehicle safety, except workers employed by the United States, a State, or a political subdivision while working for that government. An "employer" is a business affecting interstate commerce that owns, leases, or assigns a commercial motor vehicle, but not the Government, a State, or a political subdivision. "Interstate commerce" covers trade or transport between a place in a State and a place outside that State (including outside the United States), or between two places in the same State if the route goes through another State or outside the United States. "Intrastate commerce" means trade or transport that stays within a State and is not interstate. A "medical examiner" is someone licensed, certified, or registered under Federal Motor Carrier Safety Administration rules. "Regulation" also means a standard or order. "State" means a State of the United States and the District of Columbia, and in sections 31136 and 31140–31142 it also includes a political subdivision of a State. "State law" and "State regulation" include laws and regulations made by political subdivisions. "United States" means the States of the United States and the District of Columbia.
