A driver was airlifted to hospital after a Porsche plunged off a road before a two-car smash on a diversion route in the highlands.
The incident happened around 11.05am a mile north of Tyndrum on the A82 northbound and involved a white Porsche GT3 which left the carriageway and rolled down an embankment.
The driver, a 50-year-old man, sustained serious injuries and was taken by heli-med to the Queen Elizabeth University Hospital in Glasgow.
