A woman and a 13-year-old girl have been left seriously injured after a crash between two Land Rover vehicles.
They were in a Defender, towing a horse box, on the A82 near Loch Lomond when a Discovery driven in the opposite direction was in collision with them.
The 47-year-old woman driving the Defender and her 13-year-old passenger are being treated in hospital for serious injuries.
The horse that was being carried in the trailer died at the scene.
The crash happened between Duck Bay and the Stoneymollan roundabout.
The 59-year-old driver of the Discovery was not injured.
Insp Adam McKenzie, of Police Scotland, said: “This was a very serious road crash and I would appeal to anyone who witnessed what happened to please get in touch.
“If you were on the A82 around the time of the incident and may have seen either of the vehicles involved driving on the road, or witnessed the actual collision, you may be able to assist with our inquiries, and it is important that we speak to you.”
