Motorists are being warned of road chaos this morning as two major motorways are shut after serious collisions, leading to hours-long delays.
The M4 is closed eastbound between J13 Chieveley Interchange (Newbury, Oxford A34; Chieveley Services) and J12 Theale Interchange (Theale, Reading (W) A4).
National Highways is reporting that the road is closed due to a serious collision, with emergency services in attendance.
This includes Thames Valley Police, South Central Ambulance Service and Royal Berkshire Fire and Rescue, in addition to National Highways Traffic Officers.

The police will need to carry out a complex collision investigation, meaning the road will "remain closed for a protracted period".
Traffic maps suggest that the incident is not expected to clear until at least 10.30am later this morning, although this is likely to change.
Drivers will have to wait for normal traffic conditions to return at around 11.30am as police continue their investigations.
National Highways has outlined a diversion route which takes drivers towards Newbury and Thatcham before returning to the M4.

Elsewhere, motorists are also dealing with long delays during rush hour in Cumbria along the M6.
The motorway is closed in both directions between J41 Catterlen Interchange (Wigton B5305) and J42 Golden Fleece Interchange (Carlisle A6).
A lorry travelling southbound crossed through the central reservation on the northbound carriageway and overturned.
National Highways Traffic Officers and contractors are at the scene, as well as Cumbria Police, Cumbria Fire and Rescue and North West Ambulance Services.
