Arlington, VA — Installing crash prevention technologies on the front of large commercial trucks may reduce, by more than 40%, crashes in which those trucks rear-end another vehicle, according to a recent report from the Insurance Institute for Highway Safety.

IIHS Director of Statistical Services Eric Teoh analyzed data from about 2,000 crashes involving large trucks that occurred from 2017 to 2019. He found that forward-collision warning systems reduced rear-end crashes by 44%, while automatic emergency braking systems reduced the crashes by 41%. Additionally, these technologies were found to reduce overall crashes by 22% and 12%, respectively.

Front crash prevention systems employ cameras, radar or other sensors to monitor roadways, while AEB systems automatically engage brakes to prevent or mitigate collisions.


According to data from the Federal Motor Carrier Safety Administration, 4,415 fatal crashes involving large trucks occurred in 2018 – a 52.6% increase from the 2,893 recorded in 2009.

“This study provides evidence that forward-collision warning and AEB greatly reduce crash risk for tractor-trailers and other large trucks,” Teoh said in a Sept. 3 press release. “That’s important information for trucking companies and drivers who are weighing the costs and benefits of these options on their next vehicles.”
