OPP are frustrated that motorists are failing to change their driving behavior in extreme winter weather. In spite of a stern warning last week, OPP once again responded to a series of multi-vehicle collisions this week along Ontario highways. The worst crash scene was in the westbound lanes of highway 401 near Napanee where 150 vehicles and 15 tractor trailers were involved. OPP Chief Blair is urging motorists to slow down and allow extra space between vehicles. He also says drivers should use full headlights in challenging conditions.  Motorists are encouraged to visit the MTO website at mto.gov.on.ca for traveller’s information such as winter road conditions, construction reports, road closures and traffic reports.
