On Aug. 6, 2014, NHTSA issued and NPRM proposing a new 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 GVWR > 11,793 kg. 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 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 requirements 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.
Comments are due 10/6/14.
The rule would take effect 3 years after publication of the final rule.
