This astonishing video captures a vast plume of smoke sparking chaos on motorways following a fierce wildfire on a nearby mountain.

Smartphone footage showed the sky turning a fiery orange as a massive wildfire engulfed Qixingguan district in the city of Bijie in Guizhou, China, on February 22.

The clip further showed the raging flames obscuring the visibility of drivers navigating the area, as clouds of smoke billowed into the air.

Media revealed that firefighting units quickly mobilised to extinguish the fire which emerged on February 18, with many locals joining them to put out the fire.

The fire was reportedly so fierce that the helicopters used to extinguish it were driven away by the thick smoke.

Qixingguan District authorities said in a statement issued on February 19: 'At around 3 pm on February 18, a wildfire broke out in Yinhe Community, Yachi Town, Qixingguan District.

'After the fire broke out, the city and district levels immediately launched emergency response and organised the forestry crews, public security, firefighting, armed police, and other emergency forces to rush to the scene to put out the fire.'

They continued: 'Due to strong winds, the fire spread quickly in the early stage, and the fire field formed two fire lines from east to west and from north to south.

'At present, isolation belts are being set up to block the spread of the fire, and professional forces are being organised to fight the fire.

'The fire has been controlled and no casualties have been caused yet. The extent of the burnt area is being verified and the cause of the fire is under investigation.'

Chinese media reported that police have launched a probe to determine the cause of the fire. Efforts to put out the blaze are still underway.
