Police say tailgating responsible for crashes involving six buses and a truck Drivers are being warned to stop tailgating vehicles after 54 people were hurt in two accidents yesterday, with one pile-up involving five buses. Police believe the accidents were caused by drivers not keeping the recommended braking distance of two seconds behind other vehicles. Senior Superintendent Kaiser Chiu Kam-fai, head of the New Territories North traffic unit, said police were doing what they could to combat dangerous driving practices, but 'we need full support from the community to make our roads safer for everyone'. In the worst accident, three coaches, a minibus and a Citybus double-decker collided at the mouth of the Western Harbour Crossing in Western just after 8.30am. Police said a coach braked to avoid hitting a car. A minibus behind braked in time but the double-decker bus and two other coaches collided nose to tail. The Citybus vehicle, carrying commuters from Tuen Mun to Central and Wan Chai, shunted the minibus into the coach in front. Ten ambulances, six fire engines and a mobile casualty treatment centre were sent to take 40 injured people to two hospitals. A woman on the minibus said: 'A coach suddenly stopped in front and our minibus stopped in time. But a Citybus ploughed into our vehicle from behind. The impact was powerful and the windscreen and windows ... were damaged.' A passenger forced open the door and everyone rushed out. An uninjured woman on a coach said some passengers were thrown out of their seats and others were bleeding from their heads after they were slammed into the seats in front of them. Rescuers at the mobile casualty station bandaged victims before they were ferried to hospitals. Police said most victims had minor injuries to their heads, hands and legs. They were treated at Queen Mary and Ruttonjee hospitals and discharged. Three hours later, about 11.30am, a KMB bus rammed the back of a truck in the New Territories-bound lane of Tolo Highway near Hong Lok Yuen Road, Tai Po. Police said the 41-year-old truck driver, who was not hurt, had braked because of traffic. The 38-year-old bus driver and his 13 passengers - five men and eight women - were taken to Alice Ho Miu Ling Nethersole and North District hospitals. The bus driver's condition was serious last night but the other victims, aged between 24 and 52, were stable. Mr Chiu said tailgating was a frequent cause of accidents and police would continue to crack down on bad driving. 'To tackle the problem and reduce traffic accidents, we will continue to use our hi-tech equipment, like laser guns, and deploy undercover police cars with video cameras to catch dangerous drivers,' he said. Police would also launch a road safety campaign to educate the public and organise seminars for drivers from bus companies, travel agencies and other transport companies, he said.
