M20 Accident Today: Serious Crash and Car Fire Close Eastbound Motorway Between Junctions 8 and 9

A serious collision involving a vehicle fire caused major disruption on the M20 motorway in Kent on the morning of Wednesday, September 23, 2026, forcing the closure of the eastbound carriageway between Junction 8 (Lenham) and Junction 9 (Ashford).

Emergency services responded to the incident, while National Highways warned motorists that the closure could remain in place for several hours as a full collision investigation was carried out.

Serious Crash on the M20

The incident occurred on the coastbound (eastbound) carriageway between Junctions 8 and 9.

Initial reports indicated that the collision was followed by a car fire, prompting a significant emergency response.

Kent Fire and Rescue Service deployed three fire engines and a technical rescue unit to extinguish the blaze and assist at the scene. Kent Police and other emergency services also attended.

Authorities have not yet released full details regarding how the collision occurred or the number of vehicles involved.

Eastbound Closure Causes Major Delays

The closure resulted in substantial congestion along the motorway.

According to National Highways, traffic queues extended for approximately three miles, with delays of around 30 minutes reported during the initial stages of the incident.

Motorists travelling toward Ashford, the Channel Tunnel, and the Port of Dover were advised to expect significant delays and consider alternative routes.

Officials indicated that the motorway was expected to remain closed for several hours while investigators examined the crash scene.

Official Diversion Route

Drivers travelling eastbound were advised to:

• Exit the M20 at Junction 8 (Lenham).

• Follow the A20 toward Ashford.

• Rejoin the motorway at Junction 9.

Freight traffic travelling toward Dover was advised to use the M2 and A2 as alternative routes.

National Highways urged motorists to follow the signed diversion routes and allow additional travel time.

Authorities have confirmed that the incident involved a road traffic collision followed by a vehicle fire.

At the time of publication, officials had not confirmed:
