The investigation continues following a two-vehicle collision that shut down a section of the 401 overnight.
OPP and emergency responders from London were called to the westbound lanes near Veterans Memorial Parkway around 10:15 last night.
Authorities say it appears a transport truck collided with a maintenance vehicle that was being used to protect a crew painting lines on the highway.
The driver of the transport was taken to hospital with non-life threatening injuries.
No one else, including the painting crew, were hurt.
The highway remained closed for several hours to clean up the scene, but reopened around 4 o’clock this morning.
