A terrifying accident awaited several drivers on Halloween.

Shortly after 4:30 a.m. on Oct. 31, two or three vehicles were involved in a collision on Highway 400, south of Highway 88.

The accident left one of the vehicles in the active lane without lights on, said Theodore Dongelmans, acting media coordinator for the Ontario Provincial Police (OPP).

“This resulted in a domino effect, causing more cars to collide with the original vehicles,” he said.

Eight vehicles collided and the road was closed for several hours causing significant traffic delays.

One person was taken to hospital with minor injuries.

Dongelmans said a 36-year-old Scarborough man was charged with dangerous operation, intoxicated operation, with BAC (blood alcohol concentration) over .80.

Other drivers were charged with additional violations of the provincial Highway Traffic Act, he said.
