Updated at 6.12pm: Police said on Thursday they have conducted a territory-wide operation during the past two days to encourage minibus passengers to wear seatbelts. A spokesman said officers issued 165 verbal warnings and 446 summonses to passengers during the 24-hour operation, starting on Wednesday at 8am. He said the operation was conducted to help enforce a law which required minibuses to install safety belts on passenger seats and to encourage commuters to wear them. Since the law came into effect in August 2004, police have issued 1,862 verbal warnings to minibus passengers and 1,332 summonses to those failing to wear them. 'As part of the ongoing efforts to encourage passengers to protect themselves from injury, police commenced the operation on Wednesday against passengers for not wearing seatbelts,' the spokesman said. He said it was the passengers' responsibility to ensure their safety by tightening seatbelts. 'A passenger who is found not wearing a seatbelt when it is available on a public light bus is subject to a maximum fine of $5,000 and three months' imprisonment,' he warned. The number of accidents involving minibuses over the past two years hit a record low in October after the government stepped up promotion of road safety issues and the enforcement of road regulations. Transport authorities introduced a number of safety measures for minibuses after two passengers were killed and 17 others injured in a crash in North Point in 2004. These measures include more red-light cameras at major road intersections to curb speeding and tougher penalties for the jumping of red lights - including an increase in the fine from $450 to $600 and the deduction of five licence points instead of three. Speed indicators for franchised green minibuses were also made mandatory in 2005.
