A serious crash and car fire on the M20 motorway in Kent caused major disruption for motorists on Wednesday morning, September 23, 2026.
The eastbound carriageway was closed between Junction 8 at Lenham and Junction 9 at Ashford after the collision, with emergency services attending the scene.
National Highways warned that the closure could remain in place for several hours while a full collision investigation was carried out.
M20 Crash Between Junction 8 and Junction 9
The incident happened on the coastbound side of the M20 between Junction 8 and Junction 9.
Early reports indicated that the collision resulted in a vehicle fire, prompting Kent Fire and Rescue Service to send three fire engines and a technical rescue unit to the scene.
Kent Police and other emergency services also attended as crews dealt with the crash and began investigating what happened.
The exact circumstances of the collision had not been fully released in the initial reports.
M20 Eastbound Closure Causes Delays
The closure created significant congestion on the motorway, with National Highways reporting around three miles of traffic and delays of approximately 30 minutes.
Motorists travelling toward Ashford, the Channel Tunnel and Dover were warned to expect disruption and consider changing their routes or delaying their journeys.
The closure was expected to remain in place for a number of hours because investigators needed to examine the crash scene.
Diversion Route for M20 Traffic
Drivers travelling eastbound were advised to leave the M20 at Junction 8 and use the A20 before rejoining the motorway at Junction 9.
Freight traffic heading toward Dover was advised to use the M2 and A2 as an alternative route.
National Highways also warned motorists to follow the signed diversion and allow extra time for their journeys.
What Happened in the M20 Crash?
The available reports confirm that the incident involved a collision followed by a car fire.
However, authorities had not initially released a detailed account of the vehicles involved, the circumstances leading to the crash or whether anyone was seriously injured.
A separate collision on the westbound M20 near Maidstone had also caused disruption earlier in the morning, although those lanes were subsequently reopened.
