For years crash tests have been conducted on vehicles to give an idea of which models will protect you the most during an accident. But now tests are evaluating technology that can keep you out of a crash in the first place. More and more vehicles are being designed with auto brakes. Those are brakes that will engage without a driver having to do a thing, if the car is about to hit something. The Insurance Institute for Highway Safety is known for its crash test safety ratings. But as cars get smarter there’s a growing need to look beyond just crashworthiness to crash prevention.
