Every year, the U.S. sees around 40,000 traffic-related deaths, with a large portion involving impaired or speeding drivers. While discussions on how to curb these fatalities have been slow, there’s a growing sense of optimism that new measures to prevent driving under the influence (DUI) will be implemented by the end of this decade. The key? A directive tucked into the federal infrastructure law, passed in November 2021, that could significantly reduce DUI-related deaths.
The Directive’s Purpose and Goals
The Infrastructure Investment and Jobs Act, passed in 2021, included a provision aimed at tackling one of the most preventable causes of traffic deaths: impaired driving. This directive required the National Highway Traffic Safety Administration (NHTSA) to explore technologies capable of preventing intoxicated drivers from operating a vehicle.
The goal? To reduce traffic crashes and fatalities by implementing systems that could detect and respond to impaired driving. Specifically, the NHTSA was tasked with evaluating methods to measure blood alcohol levels or detect signs of impairment. If these signs exceeded certain limits, the technology would either prevent the car from starting or take action if the car was already in motion.
The law gave the agency three years to come up with a report—due by November 2024—or provide reasons why it couldn’t meet that deadline. However, the timeline has already slipped, and it’s unlikely that manufacturers will be able to meet the goal of including these technologies in vehicles by 2026 or 2027.
A Setback in the Fight Against DUI
The NHTSA was supposed to have a plan by the end of 2023. But as of the latest update, the agency has yet to reach any conclusions. In a report, the agency stated that it was still exploring the most effective methods to detect impairment, noting that several technical challenges remained unsolved.
These challenges include distinguishing between various forms of impairment—whether alcohol-related or caused by other substances—and avoiding false positives, which could prevent sober drivers from using their vehicles. The agency’s acting director, Ann Carlson, expressed concern that even if the system were 99.9% accurate, it would still generate a million false positives every day, potentially grounding millions of sober drivers.
While the NHTSA’s exploration of these technologies continues, the inability to meet the deadline raises questions about whether the intended regulations will be implemented in time to save lives.
Why This Matters
The infrastructure law’s directive was designed to address the urgent need for solutions to reduce DUI-related traffic deaths. Since the provision’s introduction, there’s been considerable hope that a technological breakthrough could be the solution, saving countless lives and reducing the burden of traffic fatalities.
With the failure to meet the deadline, the potential delay in rolling out the technology could hinder progress in achieving these life-saving measures. Without a clear regulatory framework in place, automakers may struggle to integrate these technologies into vehicles by the originally intended date, potentially putting off real progress for years.
The Political and Practical Hurdles
In 2022, an attempt by three senators from South Dakota, Indiana, and Texas to repeal the mandate was unsuccessful. Their bill, which sought to remove the directive, never made it to a vote. This effort highlighted the political resistance that such regulations can face, with some lawmakers questioning the practicality of the mandate and its implications for manufacturers.
Despite these challenges, the hope remains that the NHTSA will ultimately find a solution. The need for technology that can stop impaired driving is undeniable, and with millions of lives at stake, the stakes are high. The sooner this technology is introduced into vehicles, the sooner it can start saving lives and reducing the number of families affected by DUI-related crashes.
Looking Ahead: A Long Road to Implementation
Given the current status of the NHTSA’s work and the looming deadline, it’s unclear whether the agency will be able to present a viable solution in time for manufacturers to incorporate these technologies into their vehicles. However, even with the setbacks, the directive remains a promising development in the fight to reduce DUI deaths.
As the NHTSA continues its work, all eyes will be on how it addresses these challenges. If successful, the technologies could serve as a critical tool in preventing intoxicated drivers from getting behind the wheel—potentially making roads safer for everyone.
