Why Commercial Auto Coverage Matters in South Dakota
South Dakota’s 82,000 miles of roadway see a unique mix of farming equipment, energy-sector hazmat trucks, and cross-country semis. According to the South Dakota Department of Public Safety, commercial vehicles are involved in nearly 14% of the state’s injury crashes each year. One serious accident can sink a small outfit without adequate coverage.
- Severe winter storms and sudden hail increase physical-damage claims.
- Rural routes mean longer emergency response times and higher liability payouts.
- Out-of-state hauls often require federal filings (MCS-90, BMC-91X) that most personal auto policies don’t meet.
