The investigation revealed an 87-year-old driver was in the right lane when he attempted to change lanes and struck the front side of the semi-truck. His vehicle spun in front of the semi, causing the 55-year-old semi driver to move into the left lane and hit a third vehicle.
That third vehicle, driven by a 23-year-old from Woodhaven, was forced over the median wall and into the westbound lanes of I-94.
Michigan State Police says it will submit paperwork to the secretary of state to have driving privileges re-evaluated for the 87-year-old, since he was found at fault in the crash.
The crash happened on Wednesday, March 11. That section of I-94 in Dearborn near the Wyoming exit remained closed for several days after the crash.
All three vehicles were totaled in the fire, but no one was seriously hurt. The semi driver suffered minor injuries.
