Vehicle Safety Standards; Bus Rollover Structural Integrity, Motorcoach Safety Plan (35 pages, in English) 
6. Description of content: NHTSA is issuing this NPRM to propose a new Federal motor 
vehicle safety standard to enhance the rollover structural integrity of certain types of large 
buses (generally, over-the-road buses (of any weight) and non-over-the-road buses with a 
gross vehicle weight rating (GVWR) greater than 11,793 kilograms (kg) (26,000 pounds (lb)). The agency is proposing performance requirements that new large buses of these 
types must meet in a test in which the vehicle is tipped over from an 800 millimeter (mm) 
raised platform onto a level ground surface. The performance requirements would ensure 
that these vehicles provide a sufficient level of survival space to restrained occupants in rollover crashes. The performance requirem ents would also ensure that seats and 
overhead luggage racks remain secured and window glazing attached to its mounting 
during and after a rollover crash, and would ensure that emergency exits remain closed during the rollover crash and operable after the crash.  
This NPRM is among the rulemakings issu ed pursuant to NHTSA's 2007 Approach to 
Motorcoach Safety and DOT's Departmental Motorcoach Safety Action Plan. In addition, establishing roof strength and crush resist ance requirements, to the extent warranted 
under the National Traffic and Motor Vehicle Safety Act, would fulfill a statutory provision 
of the Motorcoach Enhanced Safety Act of 20 12 (incorporated and passed as part of the 
Moving Ahead for Progress in the 21st Century Act).
