The Seat Belt Usage by Commercial Motor Vehicle Drivers (SBUCMVD) Survey is a nationally representative field data collection program that provides estimates of safety belt use by drivers and other occupants of medium and heavy duty commercial motor vehicles (CMVs). The work is conducted on behalf of the Federal Motor Carrier Safety Administration (FMCSA) under NHTSA contract DTNH22-13-D-0284. This survey of CMVs was conducted using the sample design and field data collection methodologies similar to those used in the National Occupant Protection Use Survey (NOPUS) of passenger vehicle occupants.
