This is the terrifying moment a petrol tanker slid on a slippy road during heavy rain.

Dashcam footage shows the 10-wheeler skidding toward a retaining wall along a highway in Phuket, Thailand as a storm soaked the region on June 17.

Onlooker Ruj Nopphadom said: 'Drivers should be careful. The roads become very slippery in this weather.'

The tanker did not appear to hit other cars, but temporarily obstructed two lanes on the highway.

Thailand and neighbouring countries in Southeast Asia are at the start of their annual monsoon rainy season which sees soaring temperatures followed by powerful rain storms. The rudimentary infrastructure often struggles with the deluge, leading to widespread flash floods.
