Summary
This regulation requires buses to have stronger structural designs that can better withstand rollovers, protecting passengers from serious injury or death. The rule sets minimum safety standards that all bus manufacturers must follow to keep riders safer in accident situations.
Key Points
- 1Buses must be built with reinforced frames and roofs that can handle the stress of a rollover accident
- 2The rule applies to all new buses sold in the United States, including school buses, transit buses, and intercity coaches
- 3Manufacturers must test their bus designs to prove they meet the new strength requirements before selling them
- 4The regulation was issued by NHTSA (the National Highway Traffic Safety Administration), the federal agency responsible for vehicle safety
- 5Stronger bus structures reduce the risk of the roof collapsing or the bus breaking apart during rollovers, which could otherwise trap or injure passengers
Impact Assessment
If you are a bus manufacturer, this means you must redesign and strengthen bus structures to meet new rollover safety standards, increasing production costs and engineering timelines.
