The U.S. military demonstration that shot live-fire artillery rounds over Interstate 5 on Saturday dropped metal shrapnel on a California Highway Patrol vehicle, resulting in damage, agency officials said Sunday.

The CHP said that the shrapnel was from an explosive ordnance that was fired over Interstate 5 and “detonated overhead prematurely, striking and damaging a CHP patrol vehicle.”

The shrapnel fell on the vehicle in an area where CHP officers were gathered to close traffic along Interstate 5 in northern San Diego County, which cuts through Marine Corps Base Camp Pendleton.

State officials decided to order the closure of Interstate 5 during the live-fire exercise, conducted for a Marine Corps 250th anniversary celebration featuring Vice President JD Vance.
