Description:  TITLE: Federal Motor Vehicle Safety Standards; Bus Rollover Structural  Integrity  
AGENCY: National Highway Traffic Safety Administration (NHTSA),  Department of Transportation 
(DOT)  
ACTION: Final rule  
SUMMARY: NHTSA is issuing this final rule to establish F ederal Motor  Vehicle Safety Standard 
(FMVSS) No. 227, "Bus rollover structural  integrity," to enhance the rollover structural integrity of 
over-the-road buses (motorcoaches), and other buses with a gross vehicle weight  rating (GVWR)

  greater than 11,793 kil ograms (kg) (26,000 pounds (lb)).  This final rule, issued pursuant to the 
Moving Ahead for Progress in  the 21st Century Act (MAP -21), requires the buses to provide a 
"survival space" in a rollover test to protect occupants from  possible collapse of the bus  structure 
around them. In addition, to  reduce the likelihood of ejection, this final rule prohibits 
emergency  exits from opening in the rollover test. This final rule ensures that  bus roofs and side 
wall panels will resist deformation and intrusion  into t he occupant space in rollover crashes, and 
reduces the risk of  emergency exits becoming ejection portals in a crash.     
DATES: The effective date of this final rule is: 30 December 2024.   
Optional early compliance is permitted.  
Petitions for reconsideratio n: Petitions for reconsideration of  this final rule must be received not later 
than 14 February 2022.
