A Mississauga woman has been charged after reportedly driving on the wrong way on highways 403 and 407 early Saturday morning, police say.

Police were notified around 4 a.m. after witnesses reported seeing a car with a suspected impaired driver travelling westbound on Highway 403 near Waterdown Road. Witnesses said the car stopped on the highway, made a U-turn and started travelling eastbound on the 403, before continuing onto Highway 407.

Police officers got on the highway at Applebee Line and started slowing down traffic to avoid head-on collisions, said Ontario Provincial Police's Sgt. Kerry Schmidt.

"The vehicle surprisingly did not stop and tried to get around the officer that was there to stop it," Schmidt told CBC News.

An officer tried to stop the car by pinning it, but the car spun around slightly and the driver straightened the car and continued going the wrong way, Schmidt said.

Officers then pinned the car for the second time and the car finally stopped.

The driver, a 52-year-old woman from Mississauga, was arrested. She was charged with impaired driving, driving over the legal limit, dangerous driving, faiing to stop, as well as open liquor alcohol offences in the car.
