An OPP officer was allegedly assaulted during the arrest of an impaired driver.

Provincial police stopped a Jeep Cherokee that was being driven erratically along Highway 10 on Wednesday night in Chatsworth.

Police say the driver was impaired and while being arrested, assaulted the officer. The 46-year-old Grey Highlands woman has been charged with impaired driving, fail or refuse to provide a breath sample, and assault with intent to resist arrest.

She will appear in an Owen Sound court on May 11.
