Artillery Shell Strikes CHP Vehicle on I-5 During Marine Demo

UPDATE: An artillery shell detonated prematurely over California’s Interstate 5 (I-5) on October 20, 2025, striking a California Highway Patrol (CHP) vehicle during a Marine Corps demonstration. Fortunately, no injuries were reported, but the patrol car suffered damage from the debris, authorities confirmed today.

The incident occurred during a live-fire training event at Camp Pendleton, part of the U.S. Marine Corps’ 250th Amphibious Capabilities Demonstration at Red Beach. CHP officers were conducting a traffic break on I-5 when the live shell detonated mid-air, prompting immediate action from the agency.

CHP Border Division Chief Tony Coronado, an active Marine, expressed concern over the situation. “This was an unusual and concerning situation. It is highly uncommon for any live-fire or explosive training activity to occur over an active freeway,” he stated.

In response to the incident, the Marine Corps has launched an investigation. “We are aware of the report of a possible airborne detonation of a 155mm artillery round outside the designated impact area,” said Capt. Gregory Dreibelbis, a spokesperson for the Marine Corps. He emphasized that the demonstration underwent a rigorous safety evaluation and that firing has since been suspended.

Officials have canceled additional live-fire demonstrations following the incident. The CHP has filed an internal report, suggesting an after-action review to enhance communication and coordination protocols among federal, state, and local agencies for future training events near public roadways.

California Governor Gavin Newsom, who had closed the I-5 section ahead of the event as a precaution, criticized the decision to conduct such a demonstration over a civilian route. “This could have killed someone. This is what the White House thought was fine to fly over civilians on a major freeway,” Newsom stated in a press release, highlighting the potential dangers of using military demonstrations in populated areas.

The fallout from the incident has raised significant concerns about public safety and military protocol. As investigations continue, citizens are left to ponder the implications of military exercises conducted in close proximity to major transportation routes.

What’s Next: Officials will review safety measures and protocols for future military demonstrations. The investigation by the Marine Corps is ongoing, and further updates will be provided as the situation develops.
