Drivers have been stuck in four-mile queues on the M5 for hours after a lorry inferno sent black smoke billowing across the motorway.
The motorway is closed in both directions between junction 22 at Burnham-on-Sea, and junction 23 at Puriton, and has been out of action since 9.35am.
The blaze was first reported at around 9.20am, and the road is expected to remain shut until at least 2pm.
The vehicle was reportedly carrying ‘potentially hazardous chemicals’ – with the fire service confirming both milk powder and diesel were onboard at the time.
Some drivers were seen outside of their vehicles after the fire initially brought transport to a complete standstill.

Motorists reported being stuck at a standstill for up to three-and-a-half-hours.
Video footage of the incident showed the lorry on the side of the road, engulfed in flames, before an explosion.
The driver appeared to remain inside the cab for sometime before realising the scale of the fire and evacuating a few metres up the road.
Nation Highways said in a statement: ‘The M5 in Somerset is closed in both directions between J22 (Burnham on Sea) and J23 (Puriton) due to a serious lorry fire.
‘Emergency services including Devon and Somerset Fire and Rescue are on scene.
‘National Highways Traffic Officers are also on scene to assist with traffic management.
‘Traffic caught within the closure will be released via the rear of the queue.

Devon and Somerset Fire and Rescue Service said: ‘We are currently on-site at a lorry fire on the M5 motorway’s hard shoulder, between Junctions 22 (Edithmead) and 23 (Dunball).
‘The lorry was transporting milk powder and diesel, and we are using a telehandler to safely offload these materials. The driver is unharmed.
‘The southbound carriageway remains closed as our teams work to fully extinguish the fire; however, the northbound carriageway has now been reopened, with a reduced speed limit in place.
‘We are collaborating closely with partner agencies, including the police and the Environment Agency.’
North Somerset added it advised motorists to plan journeys carefully and check before travelling.
