The Insurance Institute for Highway Safety has commissioned a study that seems to indicate that a dramatic increase in roof safety is in order. The group's resulting newly proposed standards would require a vehicle's roof to withstand two-times the specific vehicle's weight. According to the IIHS, this change could reduce the risk of fatalities in a single vehicle rollover by more than 20%.
Do a search for "roof regulations" on Autoblog and the No. 1 result will be a post written back on August 19, 2005. That's how long it's been since the National Highway Traffic Safety Administration proposed the latest increase to the 35-year-old federal requirements that govern the strength of a vehicle's roof. The proposal was to increase the current standard of a roof being able to hold 1.5 times the vehicle's weight to 2.5 times.
Neither automakers or safety advocates, two groups that usually find little common ground, are in favor of new federal roof strength standards proposed by the National Highway Traffic Safety Adminstration that would require a vehicle's roof to withstand 2.5 times the vehicle's weight.
