A federal law requiring impairment-detection devices in all new cars has survived recent attempts to strip its funding, but implementation remains stalled due to questions about the technology's readiness. The law, known as the Halt Drunk Driving Act, was attached to the 2021 infrastructure bill and aimed to passively detect when drivers are drunk or impaired, preventing their cars from operating. However, regulatory delays and political opposition have slowed the law's rollout, with no clear timeline for final approval.

Why it matters

The proposed technology is seen as a critical step in reducing the more than 10,000 alcohol-related deaths on U.S. roads each year. Advocacy groups like Mothers Against Drunk Driving (MADD) have called the law the most important piece of legislation in the organization's 45-year history, but implementation has been bogged down by concerns about the technology's reliability and government overreach.

The details

The Halt Drunk Driving Act would allow regulators to choose from a range of impairment-detection technologies, including air monitors, fingertip readers, and scanners that detect signs of impairment. However, automakers and some lawmakers have raised concerns about the potential for false positives and the government's role in controlling vehicles. A Republican-led effort to remove the law's funding was defeated in the House, but another bill to repeal it entirely awaits a committee vote.

  • The Halt Drunk Driving Act was attached to the $1 trillion infrastructure law signed by President Joe Biden in 2021.
  • The National Highway Traffic Safety Administration is expected to report back to Congress on the law's implementation soon, but supporters predict the agency will push the decision at least into 2027.

What’s next

The National Highway Traffic Safety Administration is expected to report back to Congress on the law's implementation soon, but supporters predict the agency will push the decision at least into 2027. Even after that, automakers would still have another two to three years to install the required technology.

The takeaway

The stalled implementation of the Halt Drunk Driving Act highlights the ongoing challenges in balancing public safety, technological readiness, and concerns about government overreach. While advocacy groups and victims' families continue to push for swift action, the path forward remains uncertain, with lives potentially at stake as the regulatory process unfolds.
