A CRASH on the M40 motorway has caused huge tailbacks this afternoon following heavy rain.

The incident happened between Junction 4 High Wycombe and Junction 3 Loudwater.

Highways England closed two lanes of the motorway due to the crash which caused three miles of traffic.

The M40 has reopened since following a 20-minute clear-up.

Drivers have been warned there are 30-minute delays but this should already be starting to ease.
