Over the last decades, the United States has greatly reduced the frequency of drunk driving and and the all-too-predictable accidents that result. Thanks to advocacy efforts, educational campaigns, and evolving social perceptions of the once-common practice of getting behind the wheel after too many alcoholic drinks, the number of fatalities resulting from alcohol-impaired driving dropped by 27% between 2005 and 2014, according to the the National Highway Transportation Safety Administration.
However the news isn’t all good. According to The Centers for Disease Control and Prevention (CDC), 28 people are killed in drunk driving accidents every day, with 10,265 individuals losing their lives in 2015 alone.
While drunk driving accidents are a nationwide problem, there are state-to-state differences in how likely you are to encounter an intoxicated driver in your headlights. To determine which states’ drivers are most likely to pose a threat, the insurance comparison site Insurify analyzed over a million automobile insurance shopper applications to determine which drivers are most likely to pose a threat behind the wheel.

Methodology
Insurify provides car insurance quotes based on customers’ answers to questions about driving history, vehicle type, and other personal data. The rankings in this article are based on a set of 1.3 million automobile insurance shopper applications. Each shopper was asked whether any drivers on their policy application had been ticketed or arrested for drunk driving, allowing Insurify to calculate the percentage of shoppers in each state with a history of intoxicated driving. The data correlates well to a CDC study of driving behavior by state. Additional data from the CDC on state-level DUI fatalities from 2003 - 2012 is added to the analysis.
The following states have the highest prevalence of drunk driving in the nation.
