Erin Dewar, 28, was found by a passing lorry driver off the M9 at Cambusbarron, Stirling, on Wednesday March 13.

The mother from Montrose, Angus, was taken to Queen Elizabeth University Hospital in Glasgow, where she died the following morning.

Her family said in a statement released by police: “We are heartbroken at the loss of Erin, a mummy, daughter, sister and friend.

“Her death has come as a complete shock to us all and we will miss her dearly.

“We would like to thank all emergency services involved and, of course, the driver of the lorry who stayed with her while they tried to save her life.

“The family would also like to thank everyone for their overwhelming support and kind messages.”

Ms Dewar’s silver Ford Fiesta left the northbound carriageway between junctions nine and 10 some time before 10.30pm.

The driver of a passing truck saw a light from the vehicle and pulled over to investigate before calling the emergency services.

Inquiries into the circumstances of the crash are continuing.

Anyone with information who has not yet spoken to officers is asked to call police on 101, quoting incident number 4428 of March 13.
