This is the scary moment a wild snake slithered across a car hood trapping a terrified couple inside.

Driver Watthana Mungkhuklang was passing through a forest road when something fell in front of his sedan in Nakhon Ratchasima province, Thailand, on May 25.

Watthana slowed down until he had to pull over when he realised a reptile crawling across his car, trapping him and his frantic wife.

Footage shows the creature slowly slithering on the smooth car's surface.

He said: 'I couldn't believe what was happening. The snake looked scary. My wife was also asking me what to do. I told her I don't know.'

Watthana parked and waited for the snake to depart his car before continuing the drive home.

He added: ‘We were scared because it was our first time having the experience, but we didn't want to hurt the animal so we waited until it left us alone.'
