South Dakota requires all drivers to carry minimum liability insurance of 25/50/25 (Bodily Injury per person / Bodily Injury per accident / Property Damage):
South Dakota is a tort state with consistently low and competitive auto insurance rates. The state's combination of low population density, minimal congestion, manageable litigation environment, and active competition among carriers creates favorable conditions for affordable premiums. Required minimums of 25/50/25 are standard, and South Dakota drivers who shop across the competitive market can often find very attractive rates for robust coverage levels.
South Dakota's primary insurance risks are tied to severe weather — particularly hail. The state sits in a high-frequency hail zone, with the Black Hills region and eastern South Dakota plains both seeing significant hail events during spring and summer storm seasons. Wildlife collisions — particularly with deer and pronghorn — are also common on South Dakota roads, making comprehensive coverage particularly valuable. The Sioux Falls metro carries the state's highest rates due to population concentration, while rural counties offer among the most affordable auto insurance costs in the country.
