M40 Crash Today: Latest Traffic and Incident Update

Motorists travelling on the M40 are being advised to check the latest traffic information as a number of lane restrictions and roadworks are affecting sections of the motorway on Wednesday, September 23, 2026.

Current traffic information does not confirm a major new M40 crash requiring a large-scale emergency response today. Instead, several planned closures are listed along the route, including restrictions between junctions 4 and 5 and further southbound works around junctions 10 and 11.

One scheduled closure affects the M40 southbound between junctions 5 and 4, with the hard shoulder and lanes 1 and 2 due to be restricted from Wednesday evening into Thursday morning. The work is listed as planned maintenance rather than an emergency incident.

Additional traffic information shows planned southbound restrictions between junctions 10 and 9 and between junctions 11 and 10. These works are associated with maintenance and vegetation cutting rather than a confirmed collision.

Motorists should therefore allow additional journey time, follow temporary traffic signs and check live updates before travelling. Conditions can change quickly on the motorway, particularly when maintenance activity is taking place.

At present, there is no verified information supporting claims of a major M40 crash today involving confirmed fatalities or serious injuries. Any reports of a collision should be checked against updates from National Highways, police forces covering the relevant section and established local news organisations.

Drivers encountering an actual collision or emergency should follow instructions from emergency services and avoid approaching the scene unless directed to do so.
