The Safest Cars In America Tonight now we have the new list of the safest cars in america. So which one is at the top and what does it teach about the car in your driveway? Here's abc's senior national correspondent jim avila. Reporter: To make the safest car list today, not only does the vehicle have to master five separate crash tests, head-on, the new front-corner test, side crash, roll over roof strength and how head restraints protect those test dummies. Even after all that, the truly safest vehicles on the road have to do more. The safest, like this subaru, honda and ford include this feature, a crash warning system that beeps if you are approaching the car in front of you too quickly, and at about 20 feet from impact, brake automatically if the driver fails to. The insurance institute says those systems that average about $2,000 are worth it because the warning alone reduces accidents by 7%, and with automatic braking by 15%. The fact that they've got this advanced front crash prevention system, this is a very safe choice for people. Reporter: Other recommendations -- look for adaptive headlights that swivel as you turn the corner, reducing accidents by 10%. Electronic stability control that manages wheel slippage. And if you drive a convertible, make sure it has a pop roll bar in case of roll over. Cars are getting safer. We are seeing a reduction in crashes. Reporter: And a reduction in fatalitities over the past five years as cars have been strengthened corner to corner to pass the widest range of cash tests ever including that new one that requires more strength at the front corner of the vehicle.
