Kent Police is appealing for witnesses after a serious collision on the M25 at about 5.45am.
Two lorries collided on the clockwise slip road at junction 3 where the M25 joins the M20.
One of the drivers has serious injuries. He has been taken to Kings College Hospital in London by ambulance.
The M25 slip road at junction 3 is expected to remain closed until midday while the Serious Collision Investigation Unit carries out an investigation. Diversions are in place. Motorists are being advised to use the A2 / M2 or the roundabout at junction 3 to join the M20.
Anyone with information is asked to contact the Serious Collision Investigation Unit at Kent Police on 01622 798538.
Speed cameras which have not worked on the M25 in Surrey, Berksire and Buckinghamshire for two years will spend much of this year out of action, ITV News Meridian can reveal. We disclosed last year the cameras were not working.
The area where they do not work is between the A3 and M40. They are part of a scheme called 'Variable Speed Limits' where speeds are reduced to keep traffic flowing. The cameras are meant to catch offenders. The problem stems from new digital technology which is not properly working.
There have also been issues about the size of the warning signs not being the right dimentions and breaching regulations. Now the Highways Agency says the cameras will not work for many more months and that Surrey Police are to take them over and are working to solve the problems.
Sections of the M25 where mandatory speed limits are displayed in red rings have continued to work effectively to reduce congestion and smooth traffic flow and have operated well without fixed camera enforcement.
We are working with Surrey Police, who are taking over responsibility between junctions 10 and 16, to resume enforcement. The speed limits are enforceable by the police and the cameras will be operational by Summer 2014.
With darker evenings and temperatures falling we're being urged to make sure our cars are ready for winter. The latest research says almost half of drivers in the region don't check their vehicles ahead of the winter months.
A third of us don't take any emergency items with us - and half don't carry de-icer in the car.
Another picture just in from the M25. Anti-clockwise between junctions J25 and J24, there are currently delays of 15 minutes due to a luxury sports car on fire, closing three lanes. Normal traffic conditions are expected from 2:15 pm.
