A car crashed into the central reservation on the M40 this morning, causing traffic chaos as emergency services raced to the scene.

Traffic is still queuing on the M40 northbound, between junction 4 (Handy Cross) and junction 5 (Stokenchurch), but all lanes have since been reopened.

The authorities have been unable to confirm yet if anyone was injured in the crash, but it is known that at least one vehicle was involved in a smash with the central reservation.

Delays remain in the area, but are expected to ease now lanes have been opened again.
