The driver of a car who failed to obey a stop sign died in a collision Saturday night in southeast Iowa’s Lee County. The Iowa State Patrol reports a 2008 Ford Mustang was traveling west on 200th Street at around 8:30-p.m., when it ran the stop sign and was struck broadside by a 2016 Freightliner semi traveling north on U-S Highway 218.

After the impact, both vehicles traveled together across the median and came to rest in the southbound lanes of Highway 218. The name of the driver in the Mustang was being withheld by authorities, pending notification of family. The individual was not wearing a seat belt.

The driver of the semi, whose name was also withheld, and was wearing a seat belt, was injured, and transported by Lee County Ambulance to the hospital in Fort Madison. The semi was registered to NRG Trucking Company, from Woodridge, IL.

The accident remains under investigation.
