M25 Accident Today: Motorway Closures and Traffic Disruption Reported as Drivers Face Delays

Motorists on the M25 are being advised to expect disruption following several incidents reported on the motorway on Sunday, September 20, 2026.

Recent reports indicate that different sections of the M25 have experienced closures or lane restrictions following collisions and emergency response activity. One reported incident affected the clockwise carriageway between Junctions 10 and 11, where a multi-vehicle collision was followed by an oil spill that required clearance. Significant queues and delays were reported in the area.

Further disruption was reported on the anti-clockwise carriageway between Junctions 13 and 12, where several lanes were closed while emergency services dealt with an incident. Another collision between Junctions 6 and 5 also resulted in lane closures and lengthy delays, according to reports published during the afternoon.

However, current M25 traffic information available later on Sunday did not show an active accident closure between Junctions 21 and 22. The latest traffic feed instead listed planned overnight roadworks at Junction 30 and maintenance work at the Dartford Crossing.

Drivers planning to use the M25 should therefore check live traffic information before setting out, particularly because conditions can change quickly following collisions and emergency closures.

At the time of reporting, there was no reliable confirmation that the motorway was completely closed in both directions specifically between Junctions 21 and 22. Further updates from National Highways, police or other official traffic authorities would be needed to establish whether such a closure occurred earlier or was subsequently lifted.

Motorists are encouraged to follow signed diversions and instructions from traffic officers when approaching an affected section of the motorway.
