South Dakota Truck Laws

Throughout South Dakota, highways such as Interstate 90 and Interstate 29 are everyday routes for thousands of tractor-trailers, charter buses, flatbed trucks and other commercial vehicles. Large cities such as Sioux Falls and Rapids City, and small towns from Flandreau to Elk Point, attract a steady flow of trucks. That traffic leads to avoidable highway accidents. Every year in South Dakota, hundreds of fatal and non-fatal accidents involving commercial vehicles occur on the state’s roadways. If you or a family member has been injured in a truck accident, add to your legal team a lawyer who understands truck accident litigation and can help you collect higher compensation from an at-fault truck driver or negligent trucking company.

Trucking Laws

The Federal Motor Carrier Safety Regulations (Title 49, Parts 350-399) govern all vehicles engaged in interstate traffic.

There are some situations where a tractor-trailer or other commercial motor vehicle is involved in only intrastate travel. For example, an appliance store in Pierre may own a truck that only makes in-state deliveries.

The South Dakota Department of Public Safety has adopted Title 49, Parts 382, 383, 384, 390, 391, 392, 393, 394, 395, 396, 397, 398, and 399 of the federal regulations.
