Motorists faced major delays on a Wigan road in the afternoon rush hour following an incident.
A black car sustained significant damage and came to a halt on Whelley some time before 3.30pm on Thursday.
The incident caused huge tailbacks, with long queues of slow-moving traffic in both directions.
The disruption was so bad the gridlock extended as far as the Tesco supermarket on Central Park Way
Greater Manchester Police (GMP) went to the scene to manage the traffic.
Motorists were advised to stay away from the area if possible.
