Hong Kong police are stepping up a crackdown on street racing ahead of the Macau Grand Prix from Nov. 19 to 22.
The campaign covers the whole month of November, with special emphasis on Friday nights and weekends when illegal races are rampant.
All police districts are taking part in the operation, Ming Pao Daily reports, citing Tsang Kin-keung, superintendent of the traffic management division.
The announcement came after officers stopped 15 sports cars that were about to race on Sunday.
Police have launched 415 operations against street racers since the beginning of the year, up 70 percent from 2014.
Eleven people have been arrested compared with six a year ago.
Tsang said police will increase roadblocks and deploy more laser guns and cameras to deter racers.
Suspected vehicles will be checked for illegal modifications.
Most illegal races are not planned and take place when drivers challenge each other on the spot.
Roads with sparse traffic such as Tolo Highway and the south-bound section of North Lantau Highway are favored by street racers.
Most street racing happen during late night to the early hours the next morning.
Tsang said his division has yet to draw up a contingency plan for the Formula E Championship which Hong Kong will host next October but added his team will be ready when the event rolls around.
