Veteran road safety campaigner and former MSP David Stewart says his “prayers and thoughts” are with the families of a boy and two girls struck by a car on the A82 near Inverness on Thursday.
Two 16-year-olds are in a critical condition, while another 16-year-old girl is being treated with serious injuries.
The incident involving a white Audi Q3 happened at around 4.20pm on the Inverness to Fort William road.
The boy was taken to Raigmore Hospital with life-threatening injuries, where he remains in a critical condition.
One of the girls was also taken to Raigmore Hospital with life-threatening injuries and she was later transferred to Aberdeen Royal Infirmary.
The second girl was taken to Raigmore Hospital with serious injuries, which are not believed to be life-threatening.
Road Policing Sergeant Angus Macleod is urging people with dashcam footage to come forward.
Veteran road safety campaigner Mr Stewart said: “My thoughts and prayers are with the families of the young people hurt and I would support the police plea for dashcam footage to try to get some answers as to what happened.
“This is a dreadful incident and I feel so sorry for the families affected.”
