A 56-year-old North Bay woman suffered non-life threatening injuries when her vehicle hit the guard rails on Highway 63 near Peninsula Road.
Police say the incident was the result of the vehicle going off the road mid-afternoon last Thursday.
OPP charged the woman with an impaired driving-related offence.
North Bay OPP say the case was one of five impaired-related incidents they dealt with over five days.
Before the guard rail incident, a vehicle going the wrong way on Highway 17 hit a tractor-trailer around 3:00am Thursday.
The 37-year-old North Bay driver was hospitalized for non-life threatening injuries and was charged with impaired, dangerous driving and refusing to provide a breath sample.
Then Thursday night a single-vehicle collision in East Ferris resulted in a charge of impaired driving involving a 26-year-old North Bay woman.
East Ferris was the site for another collision where a 37-year-old Guelph man was charged with an impaired related offence.
In this case, OPP says early Saturday evening the vehicle drove into the woods and down an embankment result in non-life threatening injuries to the driver.
The last incident took place around midnight Sunday that involved a vehicle swerving on Highway 63 with its four-way flashers on.
OPP found the driver, a 57-year-old North Bay man, in his home and arrested and charged him for impaired driving.
