The driver of a transport truck has now been charged following a crash on the 401 in Chatham-Kent.
Around 3:30am Sunday, the driver of an eastbound tractor trailer lost control, crossed the centre median and rolled onto its side blocking both westbound lanes of the highway.
The driver was taken to the hospital with life threatening injuries.
His condition has since improved and the OPP have now charged 59-year-old Syed Hussan of Brampton with careless driving.
The 401 between Furnival Rd and Orford Rd was closed for several hours as part of the investigation
