A man is in a serious condition in hospital after a van collided with the back of a parked lorry in Aberdeen.
Grampian Police said the collision happened in a lay-by in Wellington Road at about 4.45am on Saturday morning.
The van driver, a 35-year-old man, was taken to Aberdeen Royal Infirmary with a head injury. His condition is described as serious but stable.
The road was closed for about eight hours while accident investigators examined the scene.
The male driver of the lorry was unhurt.
Inspector Ewan Innes, of Grampian Police, said: "Our enquiries are progressing and at this stage it is too early to establish the full circumstances surrounding the collision.
"The road was quiet at the time and obviously the weather and road conditions are a factor that will feature in our inquiries, although I would not wish to speculate at this stage of the investigation.
"The van had been driven to Aberdeen from the Dundee area and I would appeal to anyone who was on the Dundee to Aberdeen road or the A956 around the time of the collision to get in contact with us if they can recall seeing a white van being driven north about this time."
Any witnesses should call police on 0845 600 5700.
