The Obama administration announced new rood crush rules. Auto makers will have to double the crush-resistance of passenger-vehicle roofs , but critics said the new standard was too weak to prevent many rollover deaths.
Transportation Secretary Ray LaHood unveiled the new rules, which dictate that roofs must be able to withstand a force equal to three times the weight of the vehicle for cars and light trucks weighing 6,000 pounds or less. Vehicles weighing more than 6,000 pounds must have a roof-crush resistance equal to 1.5 times their weight, the first time many trucks and heavy sport-utility vehicles will be subject to such a requirement. The rules will be phased in over five years, starting in 2012.
“Rollovers are the deadliest crashes on our highways and today’s rule will help occupants survive these horrific events,” Mr. LaHood said in a statement.
