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%.
Iihs Rollover Study
There's been considerable debate between automakers, legislators and safety advocates over how roof strength correlates to deaths in rollover crashes. The majority of the focus has appropriately been heaped on SUVs, whose high center of gravity makes them more prone to rollovers, particularly when they leave the road.
