Four people were injured in the accident and taken to the hospital, according to a statement issued Friday by Macomb County Sheriff Anthony Wickersham.

He said the victims are a 22-year-old Shelby Township man who is in critical but stable condition, a 48-year-old Addison Township man who is in critical but stable condition, a 56-year-old Shelby Township man who is in stable condition and a 47-year-old Rochester Hills man who was treated and released.

On Friday, officials said it appears the driver of a commercial dump truck/trailer combination, a 55-year-old Detroit man, was traveling north on the freeway when he crashed into a vehicle that was stopped at a traffic signal at 32 Mile. That vehicle struck a vehicle in front of it, setting off a chain reaction that involved six passenger vehicles, police said.

Three other vehicles stopped for the traffic light in the left travel lane were also damaged in the collision. 

The dump truck continued for several hundred feet through a ditch and into a wooded area until it came to rest, according to authorities.

Deputies interviewed the truck's driver and he told them he believed he fell asleep for a few seconds just before the crash, the sheriff said.

Police said there was no indication drugs, alcohol or distracted driving were a factor in the crash, but they are waiting for the results of a toxicology report.

In the meantime, investigators will conduct a forensic exam of the driver’s cell phone, the statement said.
