The white Vauxhall Corsa crossed the carriageway at the Arbuthnott road junction, smashed over a barrier and careered down the steep incline covered in thick gorse bush.
The car plunged 200ft off the road. Picture by Kevin Emslie.
A major rescue operation was launched with three fire engines called to crash site at about 4.25pm.
A mountain rescue team and dive team from Scottish Fire and Rescue were also dispatched.
