Stunt driving charges have been brought against a Mississauga man, age 21.
An image of a radar gun reading 171 km/h was posted on Twitter by the Ontario Provincial Police.
West of Cambridge, in Ayr, at Trussler Rd., on Highway 401, the picture was captured. There is a 110 km/h marked speed limit.
When the posted speed limit is at least 80 km/h, drivers who exceed it by at least 40 km/h may be prosecuted with stunting.
The punishment consists of both a licence suspension and a vehicle impoundment. In addition, drivers risk a 100% rise in their insurance costs, jail time, and fines of up to $10,000.
