A driver from Fergus Falls died Saturday morning after colliding head-on with a semi in Otter Tail County, authorities say.

The crash happened around 11 a.m. on Nov. 1 on Highway 210 near mile marker 39 in Tordenskjold Township, according to the Minnesota State Patrol.

Investigators say a Toyota 4Runner driven eastbound by 55-year-old Sandra Marie Olson drifted into the westbound lane while negotiating a curve. Olson then struck a semi traveling the opposite direction, the Patrol said.

Olson, who was not wearing a seat belt, died at the scene. The driver of the semi, a 62-year-old man from Perham, was wearing his seat belt and was not hurt.

Troopers reported the road was dry at the time and alcohol was not a factor for either driver. Otter Tail County deputies, Underwood firefighters and Ringdahl Ambulance assisted at the scene.
