The incident happened at about 5am, explained Lt Surapong Pungprom of the Kathu Traffic Police.
“The truck was still there when I came on duty at 7am,” he told The Phuket News.
“There were lots of motorbikes and cars keeping clearing of the truck, and trying to slowly make their way past it,” he said.
A cement truck was called in to help tow the semi-trailer up the hill, Lt Surapong explained.
Traffic was finally cleared by 8am.
“I checked and the truck was not overweight,” Lt Surapong said.
“I questioned the driver, and the problem was that he had no experience driving in Phuket and had never driven over this hill before. The truck simply was not powered up to climb the hill on the bend,” he added.
“Luckily no people were injured and no other vehicles were damaged,” Lt Surapong said.
