South Dakota-Specific Considerations
Sturgis Motorcycle Rally
The annual Sturgis Motorcycle Rally brings 500,000+ visitors. If you drive in western SD during rally week (August), expect congestion and increased accident risk.
Tourism Traffic
Mount Rushmore, Badlands, and Black Hills attract millions annually. Summer tourism increases traffic and accident rates on I-90 and Highway 16.
Severe Weather
South Dakota sees blizzards, tornadoes, and hail. Comprehensive coverage is essential for weather damage.
Slight Comparative Negligence
South Dakota follows a "slight-gross" comparative negligence system. You can only recover if your negligence is "slight" compared to the other party's "gross" negligence. This is stricter than most states.
