A motorcyclist is dead after he was hit by a transport truck and dragged 80 metres along Hwy. 401 Wednesday morning.

The accident happened at 8:53 a.m. at Stevenson Rd. in Oshawa.

Police say a 42-year-old male victim rear ended a car in front of him and was thrown from his bike and into the path of an oncoming transport truck.

The victim was pinned under the truck for several hours as emergency crews worked to free him.

Westbound lanes from Harmony Rd. to Stevenson were closed for four hours as police investigated.
