Safety is a key feature on any vehicle on the market today, and while we don’t buy a car thinking we will crash it, if the event should arise, we need to know we will walk away from it.
So this is why every major market is handling crash tests and giving out scores, mostly on a 5 start system, to point out which vehicles will protect you better.

The National Highway Traffic Safety Administration (NHTSA) calls their tests the New Car Assessment Program (NCAP) and they crash vehicles on a regular basis. Recently the 2014 Chevrolet Impala was subjected to the NCAP tests, and came out victorious, with a full 5 stars rating.
The new Impala was fitted with a wide range of safety features, such as adaptive cruise control, crash imminent braking, lane departure warning, forward collision alert, blind zone alert, rear cross traffic alert, and the more traditional airbags (10 of them), ABS, traction control and electronic brake distribution.
