Study: GM Crash Prevention Systems Cut Police-Reported Crashes

Nov. 14, 2018—An IIHS study of General Motors vehicles with optional front-crash prevention systems adds to the evidence that forward collision warning and automatic emergency braking prevent crashes.

GM vehicles with autobrake and forward collision warning had 43 percent fewer police-reported front-to-rear crashes of all severities and 64 percent fewer front-to-rear crashes with injuries than the same vehicles without any front crash prevention technology.

For vehicles equipped with forward collision warning only, the crash rate reductions were 17 percent for all front-to-rear crashes and 30 percent for front-to-rear crashes with injuries. The results largely echo a recent IIHS study involving Acura, Fiat Chrysler, Honda, Mercedes-Benz, Subaru and Volvo vehicles.
