Police action against illegal road racers is to be increased in the run-up to the Macau Grand Prix this month in an attempt to stop Hong Kong competitors practising for the event on the SAR's roads. Deputy Commissioner of Police and Road Safety Council chairman Lau Yuk-kuen urged the Hong Kong Automobile Association to revoke the racing licences of drivers who take part in illegal road racing. He said there had been 30 cases of illegal road racing since the start of the year. 'It's not too serious so far, but we expect the activities to soar in Hong Kong as the Macau Grand Prix nears,' he said. 'Past experience has shown such a trend immediately before the event.' The Macau Grand Prix will be staged on November 17 and 18. Mr Lau said police would step up monitoring at black spots and increase intelligence gathering. Automobile Association president Jackson Ho Yi-tak said the group would work closely with police in cracking down on illegal road racing. 'If the driving licence of a registered car racer is revoked for participating in illegal road racing, his racing permit may be revoked too,' he said. Mr Ho said drivers whose licences were revoked could not take part in any local or overseas racing events. 'Illegal car racing is detrimental to the car racers themselves as well as other road users,' he said.
