Every day in China, about 200 million children go to school. Many of them take school buses. What should we do to keep these students safe on the road?
On April 5, the State Council (国务院) published new rules about school bus safety. These new rules are much stricter than the old ones.
Under the new rules, local governments must make sure that students attend nearby schools or boarding (寄宿的) schools to reduce traffic risks. Also, local governments must help kids in the countryside reach their school buses.
From now on, school buses have a speed limit of 80km per hour on highways and 60km per hour on normal roads. While on the road, other cars must let school buses go first.The new rules also say that school buses must never be overloaded (超载的).  
There are many other rules as well. A school bus must have more than seven seats. On each bus, there must be at least one adult to keep an eye on the kids. Each school bus must have a fire extinguisher (灭火器), a first aid kit (急救箱) and a GPS.
Last year, a series of school bus accidents happened in China. To stop such accidents, the Central Government decided to strengthen the rules for school buses.
The most serious accident happened in November in Gansu, when a nine-seat minibus crashed. There were 62 children inside, and 21 of them died.
