The U.S. Department of Transportation's National Highway Traffic Safety Administration (NHTSA) has a new app for iPhones and iPods that will provide real-time vehicle safety information to consumers from NHTSA's SaferCar.gov site. NHTSA's SaferCar app allows users to search its 5-Star Safety Ratings for vehicles by make and model, locate car seat installation help, file a vehicle safety complaint, find recall information and subscribe to automatic notices about vehicle recalls.
