Ontario Provincial Police say they received numerous calls Wednesday night about an eastbound car travelling at 40 km/h in Front of Yonge Township, about 25 kilometres west of Brockville.
They say the callers said the car was in the fast lane with its high beams on.
OPP made several attempts to get the driver to pull onto the right shoulder, but eventually had to make a tandem stop with cruisers at the front and rear of the vehicle to move it off the highway.
They say the driver told officers she believed the speed limit was 50 km/h.
A 47-year-old woman is charged with unnecessary slow driving, failing to obey signs and not having an insurance card.
