A motorcyclist died when his big bike hit a bus making a U-turn and caught fire in Bang Lamung district, near Pattaya, on Sunday night.
The accident happened at 10.36pm.
Police reported finding a First Transport Co, bus damaged near its right rear wheels.
Nearby lay a burning 1000cc Yamaha R1 motorcycle. Once the flames were put out they were able to get to the seriously injured and unconscious rider Kritphum Khanthong, 37. Attempts to resuscitate him were unsuccessful.
Another biker said Kritphum was travelling in their group, returning from a weekend trip. He was unable to avoid hitting the bus as it began making a U-turn, crossing in front of him.
The bus driver said his vehicle was big, so he had to make the U-turn from the left lane. The motorcyclist was travelling in the right lane and had tried unsuccessfully to swerve into the left lane to avoid the collision.
