13 Injured in Santa Clarita Bus-Gravel Truck Collision

A Santa Clarita Transit bus collided with a gravel big rig—potentially striking a third vehicle—early Wednesday morning, May 13, 2026, leaving 13 passengers injured, including at least one person in critical condition, authorities confirmed. The crash occurred near the intersection of Golden Valley Road and Centre Pointe Parkway, prompting emergency response and road closures as investigators work to determine the cause.

The Los Angeles County Fire Department responded to a mass-casualty call around 9:30 a.m., confirming that all 13 injured individuals were passengers on the bus. Video footage from the scene showed the bus on its side, with significant damage to its side panel and partial overturning of the gravel truck. The front wheels of the trailer appeared to have struck an unidentified sedan, which sustained front-end damage. The bus sustained damage primarily to its side, while the front end of the big rig also showed signs of impact.

One passenger was extricated from the wreckage and transported to a local hospital in critical condition. The remaining 12 injuries ranged in severity, though no fatalities were reported. The Santa Clarita Transit bus was operating on a scheduled route at the time of the collision and officials did not immediately provide details on the identities of those injured or the extent of their conditions.

Road closures were immediately implemented along Centre Pointe Parkway between Reuther Avenue and Golden Valley Road, with eastbound traffic rerouted to avoid the scene. The city of Santa Clarita issued alerts on social media, advising drivers to seek alternate routes due to expected delays. The incident remains under investigation by law enforcement, with no further details released at this time.
