Marine Corps Investigates Shrapnel Strike on Highway Patrol Vehicle During Camp Pendleton Demonstration
The Marine Corps has launched an investigation after shrapnel from an artillery shell fired during a live-fire demonstration at Camp Pendleton struck a California Highway Patrol vehicle yesterday, October 19, 2025.
The incident occurred as the CHP was diverting traffic on Interstate 5 during the 250th anniversary celebration for the Marine Corps. According to the CHP, an artillery round “detonated overhead prematurely,” damaging at least one patrol vehicle. No injuries were reported. Pictures from a CHP incident report show a patrol car with a hood apparently pierced by shrapnel, measuring approximately 2 inches by 2 inches. The vehicle was near Interstate 5 and Las Pulgas Road, roughly a mile from the demonstration area on Red Beach.
California Governor Gavin Newsom criticized the decision to conduct live-fire exercises over the busy Interstate 5, which carries an estimated 80,000 vehicles daily, calling it a “reckless” and “absurd show of force.” “This could have killed someone,” Newsom stated on X. The demonstration was attended by Vice President JD Vance and Defense Secretary Pete Hegseth. The incident raises questions about the balance between military training and public safety, particularly when exercises impact major transportation routes. Capt. Gregory Dreibelbis, spokesperson for I Marine Expeditionary Force, stated that the demonstration underwent “a rigorous safety evaluation, and deliberate layers of redundancy, to ensure the safety of fellow citizens,” and that live fire was suspended following the incident.

The Marine Corps investigation aims to determine the root cause of the premature detonation and prevent similar incidents in the future. Officials stated they are “committed to determining the incident’s root cause and applying findings to future missions,” and the CHP intends to review communication protocols with federal authorities regarding such events.
