A California Highway Patrol cadet died Sunday in a collision on Interstate Highway 5 at West Benjamin Holt Drive in northwest Stockton.

While no one was hurt, experts say the decision to fire live munitions over the freeway during the ceremony was highly unusual.

The artillery rounds were fired over Interstate 5 near Camp Pendleton in San Diego as part of a military demonstration for the Marine Corps' 250th anniversary.

Artillery rounds also were launched over the freeway during a rehearsal for the demonstration attended by Vice President JD Vance and Defense Secretary Pete Hegseth.

I-5 closes 11 a.m.–3 p.m. for Marine Corps 250th anniversary live-fire demo at Camp Pendleton; expect major SoCal traffic delays.

And after a half-day of back-and-forth between Gov. Gavin Newsom and the White House, it seems as if all talk of shutting down Interstate 5 in California will not take place.

A driver who died after a crash along Interstate 5 in Stockton over the weekend was a California Highway Patrol cadet, the agency said.

San Clemente became ground zero in the battle between California and the Trump administration over a pre-planned live-fire artillery round shot over the freeway during a military event at Marine Corps Base Camp Pendleton.
