M4 accident reported near Hayes, West London

A collision on the M4 motorway caused significant overnight disruption near Hayes and Hounslow in Greater London, with National Highways reporting closures on the westbound carriageway between Junction 3 and Junction 4.

The incidents were first reported late on Sunday, November 8, 2026, and continued into the early hours of Monday, November 9.

Traffic information recorded two separate collision reports: one involving the westbound entry slip road at Junction 3 and another on the main carriageway between Junctions 3 and 4.

What happened on the M4?

The first reported collision occurred at approximately 10:53 p.m. on Sunday, November 8, on the westbound M4 between Junctions 3 and 4.

A second collision was reported at approximately 11:29 p.m. on the westbound entry slip road at Junction 3.

Both incidents resulted in carriageway restrictions and overnight disruption. The available reports did not provide confirmed details about the vehicles involved, the number of people affected or the circumstances leading to the collisions.

Road closures and traffic disruption

The incidents affected motorists travelling westbound around Hayes and Hounslow.

Traffic monitoring records classified one collision as severe and the other as moderate. Both incidents were subsequently recorded as cleared at approximately 1:11 a.m. on Monday, November 9.

Motorists were advised to follow motorway signs and instructions from traffic authorities while the incidents were being managed.

Were there any injuries or fatalities?

As of November 9, the available incident records did not establish whether anyone was injured or killed in either collision.

The identities of any motorists involved and further information about the circumstances of the crashes had not been confirmed in the reports reviewed.

It would therefore be premature to describe either incident as a fatal accident.

M4 traffic update for November 9

The two overnight collision reports were recorded as cleared. Later traffic monitoring information showed no newly active M4 accident in its latest update, although roadworks and other restrictions remained listed along sections of the motorway.

Drivers should check National Highways traffic information before travelling, particularly around Junctions 3 and 4.
