Furious motorists threw punches against at other as onlookers helped separate them in a road rage fight.

Locals watched as a driver and a rider were caught in a heated argument before they were locked in a brawl outside a tire factory in Samut Prakan province, Thailand, on December 26.

Witnesses said both tried to overtake each other multiple times along a busy road before they pulled over and began shouting at each other.

Footage shows the two men fighting as concerned locals and drivers interfered.

Kamton Tongchim, 48, said: ‘It happened at about 5 or 6 pm after work. I believe the rider was the first one to overtake the driver.'

He added that the pair chased each other before stopping in front of the factory.

He said: ‘The rider approached the pickup, knocked on his window, and started shouting.

‘I don't know who is wrong. I just stood there and took videos. They punched each other two times. A passerby had to stop them.

‘I'm not sure if they continued the fight after leaving the scene. They use the road together, so they all should have calmed down before taking action based on their anger.

‘There are many more good solutions. They could have come down and talked to each other nicely.'

Villagers interfered and stopped the fight before the pair disappeared from the scene.
