The U.S. Department of Transportation's National Highway Traffic Safety Administration (NHTSA) today proposed a new Federal Motor Vehicle Safety Standard that will help reduce fatalities and injuries in motorcoach and large bus crashes by mitigating occupant ejection. 

The Notice of Proposed Rulemaking (NPRM) specifies a new impactor test on the glazing material of side and rear windows and glass panels on the roof of motorcoaches and large buses. The test simulates an unbelted occupant impacting a window on the opposite side of the bus during a bus rollover crash. The proposal would drive the installation of advanced glazing and improved emergency exit latches in motorcoaches and large buses.
