“Chinese style road crossing” became a hot topic in China from the end of last year. Now, many cities have started to punish these jaywalkers (乱闯马路的人).

“Chinese style road crossing” means crossing roads without thinking about traffic lights, as long as you are part of a crowd.

Beijing Traffic Management Bureau (北京交通管理局) announced that from April 6, people who do not wait for the green light to cross the road will receive a fine of 10 yuan. Officials from the bureau said that using the diagonal (对角线) to cross the road is also against the rules. Walkers should walk in an “L” shape.

Besides Beijing, many places have also taken steps to stop “Chinese style road crossing”. Provinces such as Sichuan, Shanxi and Zhejiang have already started to fine jaywalkers 5 to 50 yuan since last year.

Road traffic deaths top the list of deaths from non-natural causes in China, Xinhua reported. The action to punish behaviors that go against traffic rules calls on people to realize the importance of traffic safety.

However, many people complain that the red lights last too long. “But as long as the design of traffic lights is the same, everyone should follow the rulers. Otherwise the country will lose its order,” said People’s Daily.

Some cities have also paid attention to the problem. Beijing Traffic Management Bureau, for example, said it would not only focus on punishment, but also improve road safety facilities (设施), such as fixing traffic lights in a more proper way and building overpasses (天桥).
