Deadly road accidents are common in China, where traffic regulations are often flouted or go unenforced.

Violations of traffic laws were blamed for nearly 90 percent of accidents that caused deaths or injuries that year.

Last year at least 36 people died and 36 others were injured in eastern China when a packed coach with a flat tyre collided with a truck.

The bus was at maximum capacity when it crossed into oncoming traffic and hit the freight truck on an expressway in eastern Jiangsu province, the Yixing public security bureau said at the time.

A preliminary investigation determined that the accident was caused by a flat tyre on the left front wheel of the bus, the bureau said in a statement. 

The Changchun-Shenzhen expressway reopened after eight hours of rescue work.
