Road Safety and Vehicle Regulation

The article reports that a 2021 federal law requiring all new cars to include passive driver‑impairment detection technology survived a recent Republican‑led effort in the U.S. House to strip its funding, passing 268–164, but remains stuck because regulators have not finalized what systems automakers must use. The 'Honoring Abbas Family Legacy to Terminate Drunk Driving Act,' folded into the 2021 infrastructure law after a 2019 Kentucky crash that killed five members of the Abbas family, directs NHTSA to mandate in‑vehicle systems that can passively detect drunk or otherwise impaired drivers—using options such as cabin alcohol sensors, fingertip blood‑alcohol readers or eye‑ and head‑movement scanners—and prevent operation. Mothers Against Drunk Driving calls it the group’s most important law in 45 years, while the alcohol industry’s main trade group is now publicly defending the mandate against claims from figures like Florida Gov. Ron DeSantis and Rep. Thomas Massie that it amounts to a government 'kill switch' that could arbitrarily disable vehicles. The Alliance for Automotive Innovation, representing carmakers, argues the technology isn’t ready and warns that even rare false positives—say, if a driver swerves to avoid a pet—could create thousands of real‑world shutdowns, a concern regulators haven’t resolved. A separate bill to repeal the drunk‑driving sensor requirement outright is awaiting a committee vote, leaving the law on the books but its core safety technology still years from deployment while more than 10,000 people continue to die annually in alcohol‑related crashes.
