Police and rescue workers arrived at the scene on Thepkrasattri Road, southbound, near the Phuket Gateway, at 1am to find a six-wheeler overturned at the side of the road.
The truck driver, 27-year-old SuJinda Yeamloi from Songkhla, was waiting at the roadside.
Duangjit Kongbangpoe, 23, was still stuck inside the cab, crying out in pain.
Rescue workers took about half an hour to free her with hydraulic cutters, after which she was immediately taken to Thalang Hospital.
The truck driver told police that he had been driving from Surat Thani to deliver goods at a shop in Patong with his girlfriend.
He was driving in the right lane of the dual carriageway when a pickup truck came up behind him, with the driver honking his horn indicating he was going to overtake, he told police.
SuJinda said he had moved to the left lane to allow the pickup to pass, but had lost control of his vehicle and rolled over.
Police are continuing their investigation to find the cause of the accident.
