NHTSA Reports 20% Decrease in Fatal Crashes in Utah Following Lowering of DUI BAC Limit to 0.05

Introduction:
Utah has been a pioneer in implementing laws to combat drunk driving, with the state being the first to lower the blood alcohol content (BAC) threshold for driving under the influence (DUI) from 0.10 to 0.08 back in 1983. More recently, in 2018, Utah again set a new precedent by dropping the official limit for a DUI classification to 0.05, the lowest of all 50 states. This move was closely scrutinized by the National Highway Transport Safety Administration (NHTSA) in their 2022 review titled, "Evaluation of Utah’s .05 BAC Per Se Law." While initial data showed a significant decrease in fatal crashes in Utah, more recent data indicates a rise in crash-related fatalities, including those involving alcohol. This has sparked a debate on the effectiveness of the law and whether it is targeting the right offenders.

The Impact of Utah’s 0.05 BAC Law on Fatal Crashes:
One of the key findings from the NHTSA’s review was a 19.8% decrease in fatal crashes in Utah when comparing the full-year data for 2016 to 2019, following the implementation of the 0.05 BAC law. Nationwide, fatal crashes also saw a decline of 5.6% during the same period. However, further analysis using adjusted vehicle miles traveled (VMT) data revealed a 13% decline in fatal crashes in Utah. Despite these positive trends, recent data shows an increase in crash-related fatalities both in Utah and nationwide, including those involving alcohol.

Rise in Alcohol-Related Fatalities Post-Implementation of the 0.05 BAC Law:
While the overall number of fatal crashes in Utah decreased after the implementation of the 0.05 BAC law, the number of alcohol-related fatalities saw an increase. In the first full year of the law, there were 22 alcohol-related fatalities out of 932 alcohol-related crashes, and this number has been steadily rising in the subsequent years. By 2023, there were 41 alcohol-related fatalities out of 814 alcohol-related crashes in the state. This trend has raised concerns about the efficacy of the law in targeting drivers who exceed the legal BAC limit and pose a greater risk on the road.

Critiques of Utah’s 0.05 BAC Law:
Local media outlets like The Salt Lake Tribune have criticized the 0.05 BAC law, arguing that it fails to address the underlying issue of repeat offenders and high BAC levels. The focus on drivers with a BAC below 0.08, instead of those with significantly higher BAC levels, has resulted in more than 2,000 arrests between 2020 and 2023. Meanwhile, arrests of drivers with a higher BAC reading have fallen by 45% on average. This has led to calls for a more targeted approach that addresses the behavior of drivers who pose a greater risk on the roads.

Moving Forward: Addressing the Real Issues of Drunk Driving:
As the debate on Utah’s 0.05 BAC law continues, there is a growing consensus that addressing drunk driving requires a multifaceted approach. While lowering the legal BAC limit can be an effective deterrent, it should be complemented by measures that target repeat offenders and drivers with high BAC levels. Enhanced enforcement, education, and support for alternatives like ridesharing can also play a crucial role in reducing the number of alcohol-related fatalities on the roads. By reevaluating current strategies and implementing comprehensive solutions, Utah and other states can work towards creating safer roads for all motorists.
