This topic covers the Department of Transportation’s (DOT) safety regulations pertaining to drivers of commercial motor vehicles (CMVs), also known as motor carriers.
The Federal Motor Carrier Safety Regulations require employers to ensure that their drivers operate CMVs safely. This means that driving while ability or alertness is impaired, or likely to become impaired, by fatigue, illness, or any other cause is prohibited. An exception exists in cases of “grave emergency” where the hazard to occupants of the CMV or other users of the highway would be increased by compliance with this requirement. In these cases, the driver may continue to oeprate the CMV to the nearest place at which that hazard is removed.
