A man has died after a car ploughed into workmen on a busy road in Dumbarton.
The driver is believed to have lost control of his grey BMW 3 series before knocking down five men who were working on the grass verge just west of the Lomondgate roundabout at 8pm on Monday night.
Police confirmed a 59-year-old man was pronounced dead at the scene.
A 37-year-old man was rushed to Queen Elizabeth University Hospital in Glasgow where hospital staff have described his condition as serious.
Three men - aged 38, 43 and 46 - were taken to the Royal Alexandra Hospital in Paisley but were released after treatment.
The 43-year-old male driver of the BMW and his 35-year-old passenger were uninjured.
Police have now launched an appeal for anyone who witnessed the crash or anyone who saw the BMW 3 series car driving on the A82 to come forward.
Sergeant Hugh Niccolls from the Road Policing Unit at Dumbarton said: “Our thoughts are with the family and friends of the man who died and his colleagues who were injured.
“Our enquiries into this crash are continuing and I would appeal to anyone who witnessed this crash, or who was driving on this road and has dash-cam footage to contact us. I would also like to hear from anyone who saw the BMW 3 series car driving on this road before the crash took place.
“Anyone with information should contact police through 101 with reference number 3304 of 9 May.”
