Five people were taken to hospital after a single vehicle rollover Tuesday morning on Hwy. 402, just east of Oil Heritage Rd.
Lambton OPP say a pick-up truck was hauling a loaded flatbed trailer on the eastbound highway around 7:45am.
Police say the trailers tires locked up causing it and the pick-up to lose control, enter the median and flip several times.
Five people in the truck suffered minor injuries.
OPP along with the Ministry of Transportation continue to investigate.
The highway was down to one lane for about two hours.
