A car bumper on the roadway triggered a major injury crash Saturday evening along westbound Highway 4 in Antioch, according to the California Highway Patrol.
A Toyota sedan, which housed seven people, was approaching A Street around 6:15 p.m. when it stopped after spotting a bumper in its lane, according to the CHP. A Toyota minivan carrying three people promptly slammed into the sedan.
Three children were transported to local hospitals via air ambulances, according to Contra Costa Fire Department Battalion Chief Jim Huntze. The rest of the injured passengers were transported via ground ambulances.
A 14-year-old girl transported by helicopter was listed in critical condition, according to the CHP.
It is unclear at this time if those involved in the crash were wearing seatbelts, according to the CHP.
The crash temporarily closed all westbound lanes of traffic, according to the CHP.
Footage from the scene showed drivers stuck in complete gridlock. Some drivers even took the time to get out their cars and take videos.
Officers were actually headed to clear the bumper from the roadway when the crash was reported, according to the CHP.
