Police say 60-year-old Patricia C. Shaffer, of Brookville, was traveling north on SR 28, negotiating a left hand curve, and the suspension on her 2002 Subaru Impreza broke.
Shaffer was able to steer the vehicle off the road to a controlled stop on private property.
The vehicle came to a final rest facing northeast.
Shaffer was using a seat belt and was not injured, police say.
