Wassana Kaewkampa, 40, told police that she was driving her motorbike southbound and had just passed the Tha Chat Chai police checkpoint onto the island just after 6am when the truck forced her off the road at the first bend.
Ms Wassana was sent scuttling along the ground, and escaped with scrapes and bruises, but her daughter, Lantaporn Duongkhare, was flung under the truck.
Lantaporn became pinned to the underbelly of the juggernaut.
“I ran after the truck and and tried to get the driver’s attention to stop,” Ms Wassana told police. “but the truck just kept going, heading toward Phuket Town.”
Lantaporn was dragged 150m before her mangled body was dislodged, explained Maj Santi Prakobpran of the Tha Chat Chai Police.
“We are currently checking the CCTV to find better description of the truck and to bring the driver in for questioning,” he said.
Ms Wassana was taken to Thalang Hospital.
