NHTSA Introduces Tougher Vehicle Roof Standards
WASHINGTON, D.C. – U.S. Transportation Sec. Ray LaHood on April 30 announced new vehicle roof standards aimed at strengthening vehicle roof structures and improving rollover crash protection.
"Rollovers are the deadliest crashes on our highways and today's rule will help occupants survive these horrific events," LaHood said.
The National Highway Traffic Safety Administration's new regulation will double the current roof strength requirement for light vehicles weighing up to 6,000 pounds. This standard specifies that both the driver and passenger sides of the roof must be capable of withstanding a force equal to three times the weight of the vehicle.
The current standard calls for roofs to withstand 1.5 times the weight of the vehicle, applied to one side of the roof, for light vehicles up to 6,000 pounds.
Heavier vehicles from 6,000 to 10,000 pounds, which have never been regulated, must now have both sides of the roof capable of withstanding a force equal to 1.5 times the weight of the vehicle. The phase-in schedule, which begins in September 2012, will be completed for all affected vehicles by the 2017 model year.
LaHood also reminded Americans that wearing a safety belt will significantly improve the chance of survival in a rollover crash. Safety belts keep people in their seats and can prevent drivers and passengers from being ejected in rollover crashes.
"These new standards go a long way toward reducing deaths, but safety belts are the first, most important step everyone should take to protecting themselves and their families," he said.
The tougher roof crush requirements are part of a comprehensive plan to address rollover crashes, which kill about 10,000 people annually. That approach includes a mandated electronic stability control system, which helps prevent the rollover from occurring, according to NHTSA.
