UPDATE: Police later confirmed that the two men inside the pickup truck, the driver named by police as Mr Prasat Prateep Na Thalang (nickname ’Huang’) and his passenger named by police as Mr Kamet Chuayuan (nicknamed ’Darkie’), were killed in the collision. The truck driver, Piyarat Kaewprasit, 38, was taken to Patong Hospital.
Police were alerted to the accident at 1:25pm.
The 10-wheeler, registered in Nakhon Pathom province, was descending Patong Hill when it crossed into the coming lane, police reported.
The lorry slammed into the pickup, a Phuket-registered Isuzu D-Max, heading up the hill.
Patong Police reported that the truck driver was not injured in the collision.
However, Patong Police also reported that the pickup driver and passenger were "expected to be dead", meaning that formal declaration of their deaths had yet confirmed.
Patong Police urged motorists to avoid the area while the vehicles were removed from the accident scene.
Brake failure of the truck descending the hill is believed to have caused the accident.
