If any Ohio drivers wonder if those fancy automatic emergency braking systems actually work, the answer is an emphatic yes, according to a new study. The study was conducted by the Insurance Institute for Highway Safety and focused on General Motors vehicles.

Automatic emergency braking, or AEB, systems use sensors to predict impending front-end collisions and alert the driver. If the driver fails to respond, the system can automatically apply the brakes to avoid the collision. The purpose of the study was to determine how well AEB systems work at preventing rear-end striking crashes in real-world conditions. To find out, IIHS researchers asked GM to provide VIN numbers for 2013-2015 models of Buicks, Cadillacs and Chevrolets to cross-reference with police-reported accident data. During those model years, GM made AEB systems optional, so the researchers were able to compare the accident frequency of models both with and without the system.

According to the study, GM vehicles equipped with AEB systems were involved in 43 percent fewer rear-end striking collisions of all types than GM vehicles without the systems. In addition, vehicles with AEB systems were involved in 64 percent fewer rear-end striking accidents that caused injuries and 68 percent fewer rear-end striking collisions that caused third-party injuries. The results of the study echo previous studies involving the AEB systems in Volvos and Subarus. There were 2.4 million rear-end collisions in the U.S. in 2016 according to federal data. To help reduce these types of accidents, all automakers have vowed to make AEB systems standard on new cars and trucks by 2022.

Individuals injured in rear-end motor vehicle accidents may benefit from contacting an attorney about their case. Depending on the circumstances surrounding the accident, it may be advisable to file a personal injury lawsuit against the driver who caused the crash. This type of complaint might lead to a financial settlement that covers a victim’s losses.
