A woman has been airlifted to hospital after the car she was travelling in alongside two children crashed in Dumfries and Galloway.
The incident occurred around 1.40pm on the A74(M) just south of junction 15 near to Beattock on Saturday.
Police said a 37-year-old man driving a Mercedes C250 “lost control of the car” before it came off the road.
A 35-year-old woman who was a passenger in the car was airlifted to Queen Elizabeth University Hospital in Glasgow following the collision.
Hospital staff have described her condition as serious but stable.
The driver and two children aged six and nine travelling in the back of the car did not require medical treatment following the crash.
Sergeant David Kerr of the Divisional Road Policing Unit from Castle Douglas Police Station said: “Enquiries are continuing into the cause of this crash.
“The road would have been busy at the time of the crash and I would appeal to any witnesses, or anyone with dash-cam footage who has not yet spoken to officers to contact us on 101 quoting reference 1735 of July 9.”
