Motorists on the M25 anticlockwise faced delays this morning after a tractor fire - and one lane is still closed.
Two fire crews from St Albans were called to the fire at 7.15am, which closed one lane between J22 and J21A.
The fire service received eight calls from passing motorists reporting a tractor unit carrying steel marker posts was on fire.
A hose reel and breathing apparatus were used to extinguish the fire which was out by 7.33am.
Lane one is still closed while recovery works take place.
