A man is in critical condition in hospital after his car left the M9 and collided with a tree near Dunblane.
Emergency services were called to the northbound carriageway, between Junctions 10 and 11, at around 8.10pm on Thursday after a blue Audi A4 crashed.
A 39-year-old man, the driver of the car, was taken to Queen Elizabeth University Hospital in Glasgow for treatment.
His condition has been described as critical but stable.
The road was closed for around nine hours to allow investigations to be carried out and the vehicle to be recovered.
Inspector Andrew Thomson of Forth Valley Road Policing Unit said: “We are working to establish the full circumstances surrounding this incident and would urge anyone with information to get in touch.
“We would be keen to speak to anyone who saw the Audi car on the road before the incident or anyone who may have dashcam footage from the area.
“If you can help, please call 101 quoting reference 3256 of December 7.”
