A total of 21 people were killed and three more injured after a bus ran off a cliff and fell 100 meters into a river below in Guizhou province.
On Saturday night, the bus veered off a mountain road in Bijie city and plunged nearly 100 meters onto a dry riverbed according to Shanghai Daily.
It is not clear if the driver is among the 21 dead.
An initial investigation has suggested that the bus was driving illegally onto a mountain road that was only intended for small vehicles.
This is the latest in a string of fatal road accidents in China, where new drivers are increasingly overlooking traffic laws and road safety.
Road accidents reportedly killed more than 87,200 people from about 426,000 accidents in the first 10 months of 2014, a 1.9 percent increase from the same period in 2013.
A study published in 2011 by a group of Chinese and U.S. researchers concluded that the number of deadly accidents was twice as high as what police had recorded.
A similar accident occurred in January, when seven people were killed after a minivan fell into a river on while traveling from Guizhou to Chongqing.
Road accidents have become the third largest cause of death in China; killing more people than cancer, according to a study in the British medical journal The Lancet.
