BEIJING, June 12 -- Chinese police will be on the streets in numbers to crack down on drink driving during the Brazil World Cup, which will start on June 13.

The traffic control bureau of the Ministry of Public Security has alerted soccer fans to the risks of drink driving and driving while tired after matches.

About 33,580 cases of drink driving occurred during the 2010 World Cup in South Africa, with 225 accidents, leaving 91 dead and 247 injured.

Most of this year's matches take place after midnight or in the early hours because of the 11 hour time difference between Brazil and China.

As fans watch games in public venues such as restaurants, bars, food stalls and squares, the police expect a rise in cases of drink driving.

The bureau also warned against bad driving brought on by extreme moods - either euphoric or wretched - because of the results of matches.
