Officers investigating a serious road collision near Dunblane have appealed for anyone who saw the crash to contact them.

A 28-year-old man from the Glasgow area was seriously injured after his light green Honda Civic collided with trees on the M9 near the Keir Roundabout at about 14:40 on Wednesday.

The man had to be airlifted to the Southern General Hospital in Glasgow.
