Many new vehicles offer advanced crash avoidance features. The systems started out as options on a few luxury models and have steadily spread to more of the fleet. Advanced technologies assist the driver with warnings or automatic braking to help avoid or mitigate a crash. These include front crash prevention, lane departure warning, blind spot detection, adaptive headlights and park assist and backover prevention. Advances also are being made in intelligent transportation systems that allow vehicles to communicate with one another or with road infrastructure to help avoid crashes.

Front crash prevention is reducing crashes. Vehicles equipped with the technology are less likely to rear-end other vehicles, IIHS research has shown. HLDI has found that vehicles with front crash prevention have fewer claims under property damage liability coverage, which pays for damage to vehicles that an at-fault driver hits. Adaptive headlights also are reducing property damage liability claims. So far, HLDI's studies of other advanced crash avoidance systems haven't been conclusive.

Electronic stability control is an older — and proven — crash avoidance feature. Standard on 2012 and later models, ESC is an extension of antilock brake technology that helps drivers maintain control of their vehicles on curves and slippery roads. ESC lowers the risk of a fatal single-vehicle crash by about half and the risk of a fatal rollover by as much as 80 percent.
