Nineteen people were injured in a seven-vehicle collision near an entrance to Tate’s Cairn Tunnel in Ma On Shan on Monday morning.
The injured people included the bus driver and 15 of his passengers as well as the drivers of three other cars. All of the injuries were minor and the injured were sent to hospital for treatment.
The accident occurred shortly before 8am when the vehicles were about to enter the Kowloon-bound lane of Tate’s Cairn Tunnel.
Police said a KMB bus allegedly failed to brake in time and hit a light goods vehicle, which was then pushed forward to hit a private car in front.
After the collision, the bus veered into its left and collided with a lorry in front of it. The lorry then hit three other private cars.
Senior inspector Lau Chun-chuen said the vehicles hit by the bus had slowed down or stopped but the bus apparently failed to do so.
“The bus driver probably did not notice the vehicles in front had slowed before he collided with them,” Lau said.
He added that police would also look into whether speeding or mechanical failure had anything to do in the bus' failure to slow down in time.
