A MEDICAL emergency caused a collision on an A12 slip road, police have confirmed.

Officers closed the exit which takes drivers off the Stanway roundabout and onto the A12 towards Colchester at 5pm on Thursday evening.

The slip road was shut for four hours after the crash, which involved one vehicle.

A police spokesman has now confirmed the road was closed because the driver was taken ill at the wheel.

He said: “We were called to reports of a single vehicle collision on the A12 slip road at Stanway at just after 5pm yesterday evening.

“That section of road was closed for four hours while emergency and recovery services worked at the scene.

“The driver of the vehicle, who was taken unwell at the wheel, was taken to hospital.”
