Feds Propose New Design Rules for Buses to Reduce Rollover Crashes

The Department of Transportation’s National Highway Traffic Safety Administration recently 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 of large buses to ensure that passengers are better protected in a deadly vehicle rollover by ensuring that the space around them remains sufficiently 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 bus is tipped over from a raised platform onto a hard level surface.

The proposed standard would:

• Require space around occupant seating positions to be maintained to afford occupants a survivable space in a crash;
• Require the seats, overhead luggage racks, and window glazing to remain attached to their mountings during and after the test; and
• Require emergency exits to remain closed during the rollover test and operable after the test.

In a separate rulemaking action to improve safety even further, the Department 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 a motorcoach’s durability is critical to saving the lives of the passengers inside,” said FMCSA Administrator Anne Ferro.
