On August 4, while a young man in Hangzhou was caught because of killing another young man with his car, a 17-year-old girl died because of the same reason in the same city. It’s reported that the driver was badly drunk.

Cars are more and more popular for more Chinese these days. And the numbers of car accidents are increasing. From 1994 to 2008, deaths because of drunk-driving increased 7.3%. In 2009, a total of 18,371 people were killed in car accidents because of drunk driving.

In the middle of August, there were some new rules to deal with the drunk drivers:

1. If a driver’s alcohol content(酒精含量) is 20mg per 100 ml of blood, he is regarded as a drunk driver.

2. If a driver’s alcohol content is 80mg per 100ml or more, he will be held(拘留) for 15 days and have their license revoked(吊销执照)for six months, and are given a fine(罚款) of 2,000 yuan.

The first weekend, 3,167 drivers were held because of high levels of alcohol in their blood.

So many people are calling for the law to deal with drunk drivers in order to make drivers understand that drunk drinking can make serious problems.
