China's long-awaited rules on school bus safety finally came into force on Tuesday, including a list of ways aimed at reducing the risk of accident.

Among the biggest changes is that buses carrying students will be given priority(优先权) in traffic, while companies and drivers will need licenses to offer school transport services.

Officials have spent more than four months making the rules, during which time the country has been shocked by several big crashes because of overcrowded school buses.

The latest accident happened on Monday in Yangchun, Guangdong province, in which three kindergarten pupils were killed and 14 others injured.

Rules and funding

In the new rules, a school bus is considered as a vehicle with more than seven seats that is transporting children receiving the State's nine-year compulsory education (ages 6 to 15) to or from school. This can also be for preschoolers(学龄前儿童) if a parent is unable to take them to or from kindergarten(幼儿园).

School buses must also operate in routes marked in the map by governments to ensure safety.

Punishment

Companies and bus drivers who fail to meet the rules face the punishment.

Drivers against the rules will be fined 200 yuan ($32) and vehicles will be taken away from its owner if they have been used as an unlicensed school bus.
