Two people were hurt when their Toyota pickup slammed into a metal post after the driver apparently fell asleep.
Anop Saboo, 20, was critically injured in the Aug. 20 wreck on Highway 36 near the Nongprue Caltex gas station. Passenger Adisorn Boonsri, 25, sustained minor injuries.
A navy doctor from Queen Sirikit Naval Medical Center witnessed the crash and administered first aid before the two men were transported to Banglamung Hospital.
Adisorn told police they were on their way to a wedding, but Anop lost control of the truck for some reason, collided with a traffic barrier and rebounded into the metal post.
Police suspect Anop was drowsy behind the wheel.
