Another car has crashed off the road and down an embankment on the unclassified road between Muthill and Braco - the second in the space of a month.
Local councillors have been calling for warning signs on the rural shortcut, which starts at Garrick and rejoins the A822 at the war memorial in Muthill.
Strathallan ward councillor Tom Gray described last month how one driver and their passenger miraculously escaped death as their car rolled five times down the embankment.
