Police with breathalyser units may soon be visiting pubs and other drinking places to dissuade people from drink-driving, according to the head of the police traffic headquarters, Chief Superintendent Blake Hancock. At present police conduct breath tests only after accidents or when a motorist is seen driving dangerously, but the number of drink-driving cases has been rising. The number of cases rose 6.8 per cent last year, police statistics show - 1,485 drink-driving cases last year compared with 1,390 in 2003. 'One of the initiatives we were discussing is bringing those machines to certain locations to allow people to test themselves as a public relations exercise - not as an enforcement exercise,' Mr Hancock said. This would 'keep people's awareness up as to whether they are over the legal limit'. He said the scheme might be launched outside popular drinking areas. 'People would tend to think Lan Kwai Fong, Wan Chai or some of the bar areas, but the reality is drink-drivers may not come from these areas,' he said. 'They might be people who go to a restaurant and have some beer with their meal. If you know you are going out drinking for the night, parking may be difficult [in such areas as Lan Kwai Fong] and you don't want to take the car. So it's very hard to say where the problem arises.' But the increase in drink-driving was small compared with the jump in the total number of traffic offences recorded last year - up 17 per cent to 404,302 from 345,442 in 2003. Besides drink-driving, the jumping of red lights and speeding are also priorities for enforcement. The number of incidents where drivers jumped red lights increased sharply last year, 74.3 per cent, to 39,376 from 22,590 in 2003, and Mr Hancock warned that police would step up enforcement. At 210,990 cases, speeding made up more than half the traffic offences recorded last year.
