Over the last decades, the United States has greatly reduced the frequency of drunk driving 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 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 is a car insurance comparison site that provides 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:

10. Hawaii

• Drivers Reporting History of DUI: 3.2%

• Fatalities in Accidents Involving an Intoxicated Driver: 484

• First Offense License Loss: One year

While Hawaii usually evokes images of sandy beaches and palm trees, there is a darker side to the island. Ranking 10th on the list of drivers with a DUI history, Hawaii’s reputation as an island paradise is tempered by the relative frequency of drunk driving. With 3.2% of auto insurance shoppers reporting a DUI, and 2.1% of survey respondents admitting to intoxicated driving in the last 30 days, America’s only island state comes with its own vehicular perils.

9. Colorado

• Drivers Reporting History of DUI: 3.3%

• Fatalities in Accidents Involving an Intoxicated Driver: 1,702

• First Offense License Loss: Nine months

That famous Rocky Mountain High comes with an increased risk of accident due to drunk driving. With snow storms, winding passes and plenty of recreational traffic, Colorado’s roads can be a challenge in the best of times, but when you factor in the elevated incidence of drunk driving they become an even greater challenge. With stiff administrative penalties for first-time convictions, Colorado is doing its best to reduce the danger posed by DUI.

• Fatalities in Accidents Involving an Intoxicated Driver: 1,442

With 3.7% of auto insurance shoppers reporting a DUI in their past, it seems possible that the climate is taking a toll on Minnesota’s drivers.

1. North Dakota

• Drivers Reporting History of DUI: 6.7%

• Fatalities in Accidents Involving an Intoxicated Driver: 502

The unfortunate designation of the state with the highest percentage of drivers with a DUI history goes to North Dakota.

Drivers in this border state would be wise to drive defensively and, of course, never get behind the wheel after consuming too much alcohol.
