Police and emergency services rushed to the Chonburi bypass on Sunday after a Thai man who had been sitting in the road was hit by a car.
The rescue services performed CPR on Thanawit Sriduangjan, 26, who had a head injury and broken arm. While this was going on his wife was in floods of tears being console by friends just yards from the scene.
Thanawit was pronounced dead at Chonburi Hospital.
Also at the scene were two cars that were damaged - a Ford and a Toyota Vios.
The Ford driver said that he had braked and stopped after seeing a man sitting in the road. He had shined his lights at the man and taken a picture with his phone's camera and warned him that he could be hit.
Moments later he heard the sound of a truck horn then a Vios driven by Khomsan Khiawphairee, 32, smashed into the seated man who was not wearing a shirt.
Daily News suggested that the deceased man had sat in the road as a gesture to get back at his wife.
Pol Lt-Col Siwakorn Janthamenchai of the Muang Chonburi police is trying to get to the bottom of the case.
