This is the hilarious moment a young lad peeing in a bottle during a traffic jam accidentally sprays his mother.

Cheeky Patchanon Changkrit, aged six, was desperate for the loo while the family were delivering goods in Ayutthaya, central Thailand, last Sunday (06/07) afternoon.

With no time to pull over to find a toilet, the lad's father, Noppon, 35, handed the youngster an empty bottle as they waited at a set of traffic lights.

Noppon began filming and captured the moment Patchanon, whose nickname is 'Batman', missed the opening and accidentally sprayed his mother, Netwilai, 36, in the front seat.

Footage shows the mother's angry reaction as she curses the youngster, who is wearing a red Liverpool kit.

She's heard saying in the video: ''Ah, lizard! You naughty boy. You've sprayed my shirt and my head. Why don't you pee in the bottle?''

Speaking today (10/07), the boy's father, Noppon said: ''We were delivery goods for our job so we didn't have time to stop. I've done it many times before where we give Batman a bottle for him to use.

''I think it's cute so I filmed it. He's never made a mistake before, but this time he was very desperate. His mother was not happy.''
