Two stubborn truck drivers risked causing a serious accident on a motorway by refusing to let each other pass.
The immature pair were filmed on the Rama2 Express way in Bangkok, Thailand on December 12.
A truck with a blue 40ft long shipping container tried to overtake the smaller 10-wheel truck carrying building site rubble but had its path repeatedly blocked.
They were filmed swerving across three lanes and the hard shoulder - also preventing cars behind them from driving by.
When one of the drivers eventually managed to pass, the other trucker began trying to overtake him again - only to start tailgating the lorry in front.
Shocked driver Jakkrit Wihong said the two men could have caused an accident, seriously injuring themselves or other road users.
He said: "These two guys seemed to think they were the only ones on the express way. They were behaving like children and didn't care about anybody around them.''
