The proportion of bus drivers caught speeding by KMB dropped by a third in the month following a fatal accident in Tseung Kwan O. On November 9, a KMB double decker bus on route 692 fell on its side near a roundabout in Po Shun Road, Tseung Kwan O, killing two passengers and leaving over 30 injured. The driver was arrested at the scene on suspicion of dangerous driving and speeding. However, KMB operations director Tim Ip insists the company's safety record has actually improved in the past few years due to an ongoing safety campaign - and it has put new measures in place to try to prevent a repeat of the tragedy. From November to December, KMB conducted a total of 10 laser gun checks in Sha Tin, Tseung Kwan O, North Lantau, Tsing Yi and Tsuen Wan. In November, 10.7 per cent of drivers failed but this decreased to 7.3 per cent in December. Each check was conducted at various locations, and an average of 100 buses was monitored each time. On average, seven drivers were caught during each check. Ip said that 94 per cent of its fleet of 3,000 was equipped with a black box - a speed monitoring device that limits the bus' speed to 70 kilometres per hour when driving on a flat road. However, he admitted that was a limited measure and that some drivers got caught speeding on roads with a speed limit lower than 70 kilometres per hour. Also, the device does not limit speed when the bus is going downhill and some drivers were caught then. Those who were caught speeding received written warnings from the company. Some drivers were also interviewed. KMB had for many years conducted two monthly laser checks before last November, but three additional ones were introduced after the fatal accident. As of this month, a total of 12 monthly checks will be carried out at all times of the day. KMB had also compiled and distributed a safety handbook and pocket cards with safety tips to its 8,000 drivers as part of the campaign on safety. The handbook highlights aspects that drivers should pay attention to before, during and after a journey. Ip denied that the release of the handbook was because initial training of drivers was inadequate. 'Our training is very comprehensive, but because we are concerned about safety, we continue to increase [drivers'] safety awareness,' Ip said. 'The handbook lets them refresh their memory whenever they want.' Also, a database of potentially hazardous areas on each of KMB's 400 routes and safety advice will be made available to drivers this year on its intranet. In 2007, the average number of bus accidents per 1 million kilometres was 3.34. This fell to 3.15 in 2008 and 2.65 in 2009. These numbers represented incidents involving personal injuries or death, regardless of liability - for example, passengers who fell while standing on the bus or passengers injured in another vehicle that collided with a KMB bus.
