Westbound traffic is running but it's very slow. As far as eastbound is concerned, it will be closed for a few hours yet.
There's plenty of flashing lights from the emergency services, the flashing orange lights of other vehicles that have stopped in the moments after the incident, and there are a number of cones across the carriageway.

Thames Valley Police has released a statement about the crash, which happened at about 12:20 and involved two heavy goods vehicles and a minibus.
"There is currently severe congestion both ways. The westbound carriageway was temporarily closed to allow the air ambulance access to the scene and has since reopened.
"The eastbound carriageway is likely to be closed for a significant amount of time and officers are working to turn affected motorists around.
"Please remain in your vehicles if you are stuck in the traffic as emergency services require access to the M4."
There are also two critical care cars, two rapid response vehicles, six ambulances and two units from the hazardous area response team on the scene.
