Major political parties are prepared to ask for longer jail terms for drink-driving accidents that kill people - from a new maximum of 10 years imprisonment to a life sentence. Ip Kwok-him, vice-chairman of the Democratic Alliance for the Betterment and Progress of Hong Kong, said drink-driving causing death should be treated as manslaughter because, he said, the crimes were of equal gravity. 'I believe you need a very heavy penalty to put people off,' he said. The maximum penalty for drink-driving causing death was lengthened from five years in prison to 10 years last July, but the Transport and Housing Bureau will begin consulting lawmakers and the Transport Advisory Committee today on whether it should be raised any further. On January 23, six people were killed when a container truck and a taxi full of construction workers collided near the border. Police say the driver of the truck was well over the legal alcohol limit. The Democratic Party, Civic Party and Federation of Trade Unions have called for increased penalties for drink-driving causing death, but Democrat Lee Wing-tat said this should not be confined to cases with fatalities. 'What about victims who were injured or lost their limbs?' he said. The Civic Party's Ronny Tong Ka-wah agreed, but warned the government and lawmakers not to create a rigid set of penalties because of one tragedy. He agreed with Democrats, however, in that first-time drink-driving offenders should face suspensions of their licences for up to six months instead of three. Other penalties should also be reviewed, they say. Biker Force, an advocacy group founded by the victim of a drink-driver, collected signatures in Mong Kok yesterday. Its petition urges the government to stiffen penalties for drink-driving causing death. It supports the call to treat the offence as manslaughter and urged the judiciary to set a minimum sentence. The group will protest on Sunday at government headquarters.
