Motorists using the M25 today, Tuesday, September 15, 2026, are facing a number of traffic restrictions and planned closures around different sections of the motorway.
However, there is currently no reliable confirmation of a major new M25 accident today matching reports of a large emergency perimeter or a multi-agency forensic investigation.
The situation on the motorway includes several scheduled carriageway and lane closures, meaning drivers should check conditions before setting out and allow additional time for their journeys.
M25 Traffic Situation Today
Current traffic information shows multiple restrictions affecting different sections of the M25.
Among the listed restrictions are closures between Junction 20 and Junction 21A, restrictions between Junction 11 and Junction 10, and other works affecting sections around Junctions 16, 26 and 27.
Some of these restrictions are scheduled overnight rather than being caused by a newly reported accident.
Motorists should therefore distinguish between planned roadworks and emergency closures when assessing reports circulating online.
Recent M25 Incident Near Junctions 10 and 11
The most significant recent incident located in current reporting occurred on Monday, September 14, when a vehicle fire caused disruption on the clockwise M25 between Junction 10 at Wisley and Junction 11 at Chertsey.
Emergency services attended the incident and the motorway was temporarily blocked.
Traffic subsequently began moving again, although significant congestion remained while recovery work and assessment of the road surface continued.
This incident should not be presented as a new September 15 crash unless a fresh official update confirms that a separate collision has occurred.
Current M25 Closures and Restrictions
Several M25 restrictions are currently listed across the motorway network.
| M25 section | Direction | Current situation |
|---|---|---|
| J20–J21A | Clockwise | Carriageway closure listed |
| J11–J10 | Anti-clockwise | Carriageway closure listed for scheduled works |
| J12–J11 | Anti-clockwise | Lane restrictions listed |
| J26–J27 | Clockwise | Lane restrictions scheduled |
| J16–J17 | Clockwise | Carriageway/slip-road closure scheduled |
| J23–J24 | Clockwise | Hard-shoulder restriction |
| J30–J29 | Anti-clockwise | Lane restrictions/roadworks |
| J5–J6 | Anti-clockwise | Road improvement restrictions listed |
The precise status of individual sections can change rapidly as road crews complete work and traffic conditions develop.
Emergency Services and M25 Safety
Emergency services may be deployed to incidents on the M25 whenever collisions, vehicle fires, breakdowns or other hazards occur.
Drivers approaching stopped traffic should reduce speed, maintain a safe distance and follow instructions displayed on motorway signs.
Motorists should also avoid stopping unnecessarily on the carriageway or hard shoulder unless directed to do so or facing an emergency.
No Confirmed Major Accident Matching the Circulating Draft
The supplied description refers to a multi-block perimeter, tactical field units, extensive forensic evidence collection and a formal agency briefing.
Those specific details have not been independently confirmed in current reporting about a new M25 accident today.
They should therefore not be presented as established facts.
Similarly, there is currently no verified information supporting claims of multiple injuries, fatalities, a specific crash location or a particular vehicle involved in a new September 15 M25 accident.
What Drivers Should Expect
Conditions on the M25 can change quickly because of the combination of scheduled roadworks, lane restrictions, breakdowns and emergency incidents.
Drivers should expect possible delays around affected junctions and follow diversion instructions where closures are in place.
Anyone travelling through the affected sections should check the latest traffic information immediately before departure rather than relying on earlier social-media reports.
Latest Update
As of the latest available information on September 15, 2026, multiple restrictions are affecting sections of the M25, but a major new accident matching the details in the supplied report has not been independently confirmed.
A significant vehicle-fire incident occurred on the M25 in Surrey on September 14 between Junctions 10 and 11, causing temporary disruption and congestion.
Further changes to traffic conditions are possible throughout the day as planned works continue and emergency incidents are dealt with.
