A study published in the American Journal of Preventive Medicine examined the impact of Utah's 2018 law reducing the legal blood alcohol concentration limit from 0.08 to 0.05 g/dL for drivers. Researchers compared alcohol-related crash fatalities in Utah to those in six neighboring states after the policy change. The analysis found that Utah experienced a significantly greater decline in alcohol-related traffic deaths compared to the surrounding states, suggesting the lower BAC threshold was effective in reducing drunk driving fatalities.
Why it matters
This evidence suggests that lowering legal BAC limits could be an effective policy intervention to reduce drunk driving deaths in other states and jurisdictions. The findings may inform legislative decisions about traffic safety regulations and demonstrate a potential method to improve public health outcomes through stricter alcohol-impaired driving laws.
A new analysis has found that after Utah lowered the legal blood alcohol concentration (BAC) limit for driving from 0.08 to 0.05 g/dL, alcohol-related crash fatalities declined significantly more in Utah than in its six contiguous states. The findings from the study published in the American Journal of Preventive Medicine, provide timely evidence that lowering the BAC limit may save lives and point to broad public safety benefits.
