A shocking accident happened in Chongqing, China on Sunday when a bus plunged 50 meters (164 ft) off a bridge into the Yangtze River. All fifteen people on board died.

The sad and disturbing truth is that the crash could have been avoided had it not been for an angry passenger attacking the driver.

Security footage from the bus shows a woman hitting the driver who then strikes her back moments before the bus fell from the bridge. As the driver got distracted by the passenger, he lost control of the bus. The vehicle entered the opposite lane and smashed through the safety barriers, landing in the river.

According to the police, it was the fight that caused the crash. Angry because the driver had refused to make a stop, a 48-year old woman hit the driver with her mobile phone. Another footage from a nearby vehicle shows the bus swerving across the other side of the road, colliding with an oncoming vehicle and then smashing through the guardrails and falling into the Yangtze.

Unfortunately, the huge rescue operation that included teams of divers, boats, and cranes found no survivors. The bus was pulled out from the bottom of the river, 71 meters (233 ft) below the surface.

The shocking crash was a deadly mix of road rage and distracted driving. Most social media comments from China blamed the passenger for the crash but others said the driver aggravated the situation by fighting back.
