Two childish lorry drivers risked causing a serious accident on the Rama 2 Expressway in Bangkok by refusing to let each other pass.
Footage of immature pair was filmed by another motorist and shared to Facebook where it quickly went viral.
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.
