Police are appealing for witnesses following a two-vehicle collision on the A69 dual carriageway in Northumberland.
It occurred westbound, approximately one mile west of the exit slip road for Heddon-on-the-Wall, at approximately 12.50am yesterday.
A white Dacia Sandero mini 4x4 vehicle, for reasons yet to be established, collided with the rear of an articulated lorry which was parked in a lay-by.
Emergency services attended, the road was closed and local diversions were put in place.
The driver of the Dacia, a 64-year-old man, was taken to the Royal Victoria Infirmary, in Newcastle, and is described as being in a serious, but stable condition.
The road was closed for just over five hours to enable the casualty to be dealt with and the scene to be examined and the vehicle to be removed.
Motor Patrol officers are keen to speak to anyone who may have seen the collision occur or the white Dacia prior to the collision. The vehicle had travelled from Stamfordham Road onto the A1 southbound and then onto the A69.
Anyone with information should call police on 101, quoting reference number 63 of 19/02/17
