A coach fire closed part of the M25 near Heathrow Airport earlier.
The vehicle caught light at about 06:10 GMT, and Surrey Fire and Rescue was called to the anti-clockwise stretch, between junction 12 for the M3 and 13 for Staines and Egham.
Crews extinguished the fire just after 08:10, but Highways England remained at the scene to clear the wreckage.
All lanes had reopened by 11:15, but miles of queuing traffic saw continued delays to motorists.
