Drivers faced major disruptions on a busy motorway following a collision that flipped a vehicle upside down and brought emergency responders rushing to the location.

Congestion is mounting on the M25 heading anticlockwise between junction 9 for Leatherhead and junction 8 for Reigate.

Closed-circuit television footage displays an inverted automobile lying directly on the road while response units manage the area.

Additional automobiles navigate past the accident site in single file because authorities blocked off one lane using traffic cones.

Drivers shared accounts of hold-ups lasting about 12 minutes, while overhead views reveal extended lines of stalled vehicles.

Travel officials estimate that regular traffic movement will return between 11.26am and 11.41am this morning.
