Riepilogo
NHTSA is considering whether to grant a petition to amend Federal Motor Vehicle Safety Standard (FMVSS) No. 105, Hydraulic and Electric Brake Systems, and FMVSS No. 121, Air Brake Systems, to require that school buses be equipped with a parking brake warning system that activates when the school bus engine is turned off, the transmission is in neutral, and the parking brake has not been applied. The petition was submitted by Schmitty and Sons School Buses, a school bus operator that is concerned about the possibility of school bus roll away crashes due to the driver not applying the parking brake. The petitioner cited several instances in which this has occurred. This request for comments notice seeks to obtain information to help the agency determine the magnitude of the problem and the potential effectiveness of the proposed warning system.
