South Dakota Accident Lawyer Involving under ride collision

Aug 8, 2025 | 18-Wheeler Accidents

At Northern Plains Justice, LLP, our Sioux Falls truck accident lawyers have decades of combined experience helping victims of catastrophic truck crashes — including one of the most deadly types: underride accidents.

An underride crash occurs when a smaller passenger vehicle slides beneath the rear or side of a tractor-trailer. Because large trucks sit so high off the ground, the top of the car can be sheared away on impact. These collisions are often fatal, and survivors may suffer devastating injuries such as traumatic brain damage, spinal cord paralysis, amputations, or permanent disabilities requiring lifelong care.

Our attorneys understand the long-term toll these wrecks take on families. We build strong legal cases to recover maximum compensation for medical costs, lost income, pain and suffering, and — in tragic cases — wrongful death claims.

Dangerous Roads and Intersections in Sioux Falls

While underride crashes can happen anywhere, certain Sioux Falls highways and intersections are more prone to 18-wheeler and semi-truck collisions:

  • Interstate 29 (I-29) – A key north-south trucking corridor with heavy freight traffic and frequent rear-end collisions.

  • Interstate 90 (I-90) – Long stretches, winter ice, and high truck volume make this highway a common site of fatal underride and rollover crashes.

  • Cliff Avenue & Benson Road – Industrial traffic from nearby plants increases the risk of large-vehicle wrecks.

  • 41st Street & Louise Avenue – One of the busiest intersections in Sioux Falls, where congestion often leads to car-vs-truck collisions.

  • Highway 42 (Arrowhead Parkway) – Agricultural and freight trucks navigate narrow lanes and sharp curves, heightening underride and jackknife risks.
