Northeast Radio SD News - Reliance, SD - A multi-vehicle collision claimed two lives and left several others injured on Friday afternoon in Lyman County. The crash occurred at approximately 3:44 p.m. on Interstate 90, five miles west of Reliance.

According to preliminary reports from the South Dakota Highway Patrol, the incident began when a 2025 Kenworth traveling westbound near mile marker 244 slowed down due to a potential crash ahead. A 2008 Mercury Sable then collided with the rear of the semi-truck, triggering a chain reaction involving three additional vehicles: a 2025 Ford F-150, a 2013 Ford F-150, and a 2010 GMC Yukon.

The driver of the Mercury Sable, a 28-year-old male from Colome, and a front-seat passenger, a 27-year-old male from Martin, were pronounced deceased at the scene. Two other passengers in the Sable, a 27-year-old male from Alexandria and a 26-year-old male from Hartford, sustained serious but non-life-threatening injuries.

The collision resulted in several other injuries across the involved vehicles:
