You want to run across the street to catch the bus which is leaving soon? But wait! You’d better not. If a policeman sees you, you’ll have to pay a fine (罚款).

New traffic laws (交通法) say that if people cross the street when the light is red, they can be fined as much as 50 yuan.

Traffic accidents killed more than 104,000 people in China last year. Chinese cities have more cars than ever. Drivers and pedestrians (行人) must work together to make the streets safer.

The law has new rules for drivers and pedestrians. Drivers have to slow down when they are close to crosswalks. If people are in a crosswalk, cars must stop to let them pass.

There are rules for bus drivers, too. If bus drivers smoke, drink or make phone calls while driving, they can be fined. Buses that carry too many people are also against the law.

Pedestrians will have to walk more safely under the new law. They must cross streets at crosswalks. Also, they shouldn’t climb over the fences (栅栏) along streets.

Do you bike to school? It’s not a good idea to carry classmates on the back. You could be fined 50 yuan.

And stay in the bike lane (慢车道) when you’re riding. The big roads are for cars and buses.

Do you like to ride your uncle’s motorbike? When you put on your helmet (头盔), ask him to put one on, too. People on motorbikes must wear helmets, the new law says. If they don’t, they’ll have to pay 200 yuan.

Do you ride in cars often? Don’t forget to put on your seat belt (安全带), even if you’re going for a short taxi ride. It could save your life.

If you see a hit-and –run (肇事逃逸), tell the police. They may give you a reward (奖赏). And don’t be afraid to help people to the hospital if they are hurt in an accident. Don’t worry about money. The new law says that doctors must take care of them even if they can’t pay right away.
