This isn’t just a drinking story.
South Dakota consistently ranks at or near the top nationally for DUI arrests per capita. Depending on the analysis, the state is first or second in the nation, with arrest rates approaching 900 to 940 per 100,000 people—well above neighboring states and far above the national average.
That’s the headline number. But it misses the deeper point.
South Dakota’s DUI ranking is the collision of rural geography, enforcement choices, and cultural habits that haven’t kept up with how the state actually works anymore.
A quiet shift in who’s getting arrested
Between 2021 and 2025, more than 30,000 people were arrested for DUI in South Dakota. More than 8,200 of those arrests involved women, placing South Dakota second nationally for DUI arrest rates among women.
That shift suggests changing drinking patterns, changing enforcement visibility, or both—and reinforces that DUI risk isn’t confined to one demographic.
Why this matters even if you never drink and drive
High DUI rates correlate directly with fatal and serious-injury crashes. More than one-third of South Dakota traffic deaths involve impaired driving—one of the highest shares in the country.
That affects everyone: insurance costs, emergency response capacity, rural hospitals, and families far removed from the original decision.
What to watch next
The South Dakota Highway Patrol plans sobriety checkpoints in 16 counties in January alone. Arrest numbers may stay high, but enforcement alone won’t solve the mismatch between rural life and safe transportation options.
The forward nudge
South Dakota doesn’t need to normalize drunk driving to explain these numbers—but it does need to stop pretending this is only about personal failure.
As long as the state relies on long drives, limited options, and late decision-making, DUI risk will remain baked into everyday life.
