DRAMATIC footage has captured a lorry exploding into a huge fireball on the M25, sparking severe delays for thousands of drivers this morning.
The motorway is closed in the clockwise direction between Junction 5 in Kent and Junction 6 in Surrey because of the devastating blaze.
The M25 clockwise carriageway is "likely to remain closed throughout the day".
This is due to the need for specialist equipment to remove the lorry with the road likely requiring resurfacing.
A video posted on social media showed the moment the lorry burst into flames bringing traffic to a standstill.
Drivers stuck on the motorway filmed the burning wreckage as fire crews tackled the blaze.

It is understood the driver is safe following the horror motorway accident.
The blaze has also closed the M26 westbound between J2A near Wrotham Heath in Kent and M25/A21.
The anti-clockwise carriageway has re-opened but lanes 3 and 4 remain closed within J6.
Cops, fire crews and National Highways traffic marshals raced to the scene.
National Highways said: "If this incident impacts on your planned route, please allow extra journey time."
A spokesperson added: "Plan ahead, you may wish to re-route or even delay your journey.
"Further information is available from National Highways by visiting our website and travel apps, or via our regional 'X' feed.
"Our 24/7 contact centre team is also available to provide up to the minute information on 0300 123 5000."
National Highway Traffic officers have remained on the scene to assist with traffic management.
Frustrated Motorists have taken to X, formerly Twitter, to find out when the congested roads will reopen.
One user wrote: "Any idea when fully open?"
National Highways responded: "Hello, unfortunately, no estimated time for re-opening at the moment.
"Please keep an eye on our feed for updates. Thank you for your patience."
One unhappy driver commented: "This has been shut for seven hours and still you’ve no idea when it will even partially open!"
Meanwhile, a separate incident at the Dartford Crossing between Kent and Essex is also causing major congestion.
National Highways said the northbound Dartford east tunnel is closed as overnight roadworks overran because a maintenance vehicle broke down within it, requiring emergency resurfacing works.
