Careless driving charges have been laid for Thursday’s head-on crash east of Listowel.
OPP say they have charged a 19-year-old Kitchener woman.
It happened just before 2:30 p.m., when the driver of an eastbound car was attempting to pass a slower vehicle on Perth Line 86, striking a car in the oncoming lane.
A 68-year-old man and 69-year-old woman remain in hospital with non-life threatening injuries.
The crash closed Highway 86 between Perth Road 140 and 131 for several hours.
The 19-year-old sustained only minor injuries.
