The woman died at the scene, on Thepkasattri Road north of the junction with the road to the five-star resorts along the Mai Khao coast, about 4.30pm.
A Chinese man on a motorcycle in front of the truck caused the driver of the truck to brake in the left-hand lane.
As a result, police say, the truck clipped the Chinese man's motorcycle, injuring him slightly.
His knees were grazed.
But worse was to come when a woman on a motorcycle behind the truck slammed into its rear, with her vehicle sliding beneath the truck and becoming wedged.
The rider died at the spot. Her body was taken to Thalang Hospital.
It was the sixth truck-related death in five days with a cement truck still having its load drained on Phuket's Patong Hill this evening after it toppled while descending towards Phuket City, killing two women on a motorcycle instantly.
Tailbacks were extending down the hill as far as Tiger Kindom, a traveller told Phuketwan tonight.
On Thursday, two Burmese laborers were killed after being thrown from a truck that flipped as it failed to negotiate a hill north of Patong on the road to Kamala.
The truck rolled back, spilling about 30 people into the roadside verge. Two of the Burmese died.
The following day, a truck laden with chlorine lost its brakes descending the hill towards Patong from Phuket City and swept aside motorcycles in its path, killing a female rider.
A concrete truck spilled into a ditch at the weekend on Kamala Hill, but there were no fatalities.
Today's three deaths took the tally to six truck-related deaths on Phuket in five days.
May we request to all senior civil servants a compulsory drive by motorcycle to go to work and for daily life in order they understand the misery that all Phuketians are suffering each day of the year.
