In less than seven hours Thursday morning, Lambton OPP attended 11 incidents on area roads.
Constable Chris Doupe says two were collisions involving more than one vehicle.
"We're having a lot of difficulty in the [Hwy.] 402, Hwy. 40, Oil Heritage Rd., Petrolia Line and Mandaumin Rd. areas," says Doupe. "So far we have had nine vehicles enter the ditch including three tractor-trailers."
Doupe says the majority of incidents could have been avoided if motorists would slow down in poor road conditions.
OPP responded just before noon to a collision on Hwy 40 at Indian Rd. S.
Around 4pm, officers responded to a cruiser being struck on Hwy. 402 at Centre Rd. and Hwy. 81 near Strathroy that had closed the westbound lanes. The highway was reopened to traffic around 6pm.
No serious injuries were reported in any of the collisions.
Sarnia's Superintendent of Roads Tony D'Agostini says plowing and salting operations will continue until conditions improve.
He anticipates crews will begin tackling side streets Thursday evening.
The snow will taper off in the afternoon but strong winds will continue to cause blowing snow, especially in outlying areas.
