What the agency says
This document amends Federal Motor Vehicle Safety Standard (FMVSS) No. 208, "Occupant crash protection," to require a seat belt use warning system for rear seats. The rule also updates and enhances the current seat belt warning requirements for the driver's seat belt and extends these requirements to the front outboard passenger seat. The final rule applies (with some exceptions) to passenger cars, trucks, most buses, and multipurpose passenger vehicles with a gross vehicle weight rating of 4,536 kilograms (10,000 pounds) or less. This document also makes related amendments to FMVSS No. 101, "Controls and displays."
