A crash on the M55 slip road onto the M6 has brought rush hour traffic to a standstill.
Motorists are facing heavy delays on the eastbound M6 all the way back to J3, while emergency services deal with a crash on the M6 slip road.
In a photo captured by police, a grey car lies on its side on the wrong side of the barriers on the slip road.
In a caption accompanying the photo, officers said: "A vehicle has collided with the barrier and rolled into the ditch on the M55 East slip road merging with the M6 South".
They said the driver had fled the scene, and asked anyone who witnessed what happened to call 101.
One lane of the slip road is closed due to the crash.
Highways England said: "Traffic officers are at scene. Expect delays in this area."
They confirmed that average speeds on the approach to the M6 exit are 10 mph.
The disruption is currently expected to last until at least 7:30pm.
