A collision on the M25 motorway near St Albans caused significant traffic disruption on Friday, November 6, 2026, with three lanes reportedly closed as emergency services and traffic authorities responded.

The incident occurred on the clockwise carriageway between Junction 21A and Junction 22, close to St Albans in Hertfordshire. The closure affected motorists travelling around the busy motorway, resulting in congestion and delays.

Traffic updates indicated that the disruption involved an overturned vehicle, with lanes two, three and four of the four-lane carriageway temporarily closed.

Three Lanes Closed Following M25 Collision

The accident created challenging conditions for drivers approaching the affected section of the motorway. With most of the carriageway unavailable, traffic was forced to move through the remaining open lane.

The incident was reported shortly after 7 p.m., prompting traffic management measures while the situation was assessed and arrangements were made to clear the obstruction.

Motorists approaching Junction 22 and travelling towards the surrounding Hertfordshire area were advised to anticipate delays and allow additional time for their journeys.

Emergency Response and Vehicle Recovery

The reported overturned vehicle required attention from emergency and traffic management personnel. Such incidents can create additional risks for passing motorists, particularly when damaged vehicles obstruct multiple lanes.

The precise circumstances of the collision, including how many vehicles were involved and whether anyone sustained injuries, had not been independently confirmed.

Authorities had not released details about the identities of those involved or whether anyone required hospital treatment.
