The National Highway Traffic Safety Administration (NHTSA) has upheld its decision to require automatic emergency braking (AEB) technology in all new passenger vehicles by 2029, despite pushback from the automotive industry. The new regulation, which aims to improve road safety by reducing accidents and saving lives, will remain largely unchanged after a series of minor adjustments. NHTSA’s decision is a significant win for safety advocates, who argue that AEB technology has the potential to prevent thousands of injuries and save hundreds of lives each year.

The rule, which was finalized in April, has sparked criticism from the auto industry, particularly the Alliance for Automotive Innovation, which represents major U.S. automakers. The group claims that the AEB requirements are impractical and could drive up vehicle prices, making it more difficult for consumers to access affordable transportation. Their primary concern centers on the technology’s performance requirements, such as automatic braking at speeds up to 90 mph and detecting pedestrians in both daylight and at night.

Despite these concerns, NHTSA has chosen to push forward with the regulation, arguing that the benefits far outweigh the potential drawbacks. Research shows that AEB can significantly reduce rear-end collisions and pedestrian accidents, which have been a growing concern as road fatalities remain at historic highs. According to NHTSA, the new rule will address a critical safety gap, helping to prevent accidents that could otherwise result in fatalities or serious injuries.

NHTSA’s decision is part of a broader effort to improve road safety, which was outlined in the 2022 Bipartisan Infrastructure Law. This regulation follows a voluntary commitment by automakers in 2016 to install AEB on nearly all new vehicles. By 2023, 20 automakers had already adopted the technology, equipping 95% of their new vehicles with AEB systems.

While the rule has faced strong opposition from the automotive sector, safety groups are celebrating the move as a crucial step toward reducing traffic fatalities and injuries.
