Three people were injured when a heavy truck went out of control and rammed into a lamp post, which fell and struck a second truck, police said on Monday.
The driver was trying to change lanes on a curve near Mei Foo when the accident happened around 10.15am on Monday, said Senior Inspector Ng Chun-piu.
The truck, carrying a shipping container loaded with over 15 tonnes of cloth, was travelling westbound in Ching Cheung Road.
It rammed into a road divider, hitting two lamp posts. One of the posts fell and hit a truck travelling in the opposition lane, injuring its driver and a passenger.
The container truck driver was trapped in his cabin for an hour after the crash. He was unconscious when firemen pulled him out and sent him to hospital.
The driver and passenger of the second truck were also sent to hospital for slight injuries.
