Proposed NHTSA Regulations to Protect Passengers in Motorcoaches and Large Buses
The United States Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) proposed a new federal motor vehicle safety standard to protect motorcoach and other large bus passengers in rollover crashes. The proposal aims to improve the structural design to ensure that passengers are better protected in rollover crashes by ensuring the space around them remains intact and the emergency exits remain operable.
The proposed standard would establish performance requirements that each new motorcoach and large bus must meet when subjected to a dynamic test in which the motorcoach or bus is tipped over from a raised platform onto a hard level surface. The proposed standard would:
- Required space around occupant seating positions be maintained to afford occupants survivable space in a crash
- Requires seats, overhead luggage racks and window glazing to remain attached to their mountings during and after testing; and
- Require emergency exits to remain closed during the rollover test and operable after test.
Both the proposed test procedure and performance requirements are closely modeled after European regulations for large buses. In a separate rulemaking action to improve safety even further, NHTSA is planning on finalizing requirements later this year for stability control technologies in these vehicles, which would help prevent rollovers from occurring.
“Approximately 700 million trips are taken on commercial buses each year. Raising the standard for motorcoache’s durability, in the event of a crash, is critical to saving the lives of the passengers inside.” said FMCSA Administrator Ann Ferro. “In addition to taking critical steps to improve the structural design of buses, we are committed to further increasing motorcoach safety through stricter oversight, in-depth investigations into high risk companies, and by ensuring that drivers are properly licensed and medically fit for the job.”
