The National Highway Traffic Safety Administration (NHTSA) is considering new crash tests and vehicle design rules to minimize injuries and fatalities caused when sport utility vehicles and pickup trucks collide with cars, according to the Detroit News. NHTSA chief Dr. Jeffrey Runge told reporters June 5 that reducing lethal crashes between cars and light trucks would be the highest vehicle-related priority during his tenure. The agency will evaluate the stiffness, mass and geometry of vehicles to search for ways to reduce the number of deaths and injuries to passengers when cars are struck by increasingly popular SUVs, pickups and minivans. "The fleet has changed," Runge said. "The need for a look at vehicle compatibility has never been more compelling than now."
