A serious multi-vehicle collision has forced the closure of a major stretch of the M11 motorway, sparking severe delays for drivers this morning.
Details of the M11 Motorway Crash
National Highways confirmed that the incident, involving two cars and a van, occurred at approximately 10:30am on Wednesday, 4 December 2025. The collision has led to the closure of the M11 southbound between junction 7 (Harlow) and junction 6 (M25 interchange).
Emergency services, including police and ambulance crews, are currently at the scene alongside National Highways traffic officers. Their immediate priority is to attend to any casualties and clear the wreckage to restore traffic flow.
Severe Traffic Disruption and Delays
The closure is causing significant disruption on one of the key routes into London from the north. Drivers are being urged to avoid the area if possible and to expect long delays.
National Highways has implemented a full closure of the southbound carriageway to allow emergency teams to work safely. Diversion routes are in place, but traffic is expected to be heavy on surrounding roads as motorists seek alternative paths.
Ongoing Situation and Advice for Motorists
At this stage, the extent of any injuries is not yet publicly known. The cause of the multi-vehicle crash is under investigation by the authorities.
Motorists planning to use the M11 southbound are strongly advised to check live traffic updates before travelling. Commuters and long-distance travellers should allow considerable extra time for their journeys or consider postponing non-essential trips until the situation is resolved.
The closure and subsequent recovery operation are likely to impact traffic for several hours. Updates on the reopening of the motorway will be provided by National Highways and local police forces as the situation develops.
