Vehicle Fire on I-15 in Fallbrook Sparks 10-Acre Wildfire and Temporary Evacuations

A vehicle fire on Interstate 15 (I‑15) north of Mission Road in Fallbrook, California, ignited brush on a nearby hillside and grew to nearly 10 acres, prompting temporary evacuations and traffic closures on Thursday afternoon. Cal Fire reported the blaze, named the Mission 2 Fire, as it spread to 9.9 acres of vegetation and was brought under control by 2:30 p.m. The incident was contained without reported injuries.

The fire began after 1 p.m. when a vehicle on the northbound I‑15 caught fire and the flames jumped to surrounding brush. Cal Fire crews arrived quickly and worked to stop the forward spread. By 2:30 p.m., the fire’s advance had been halted, and the agency began building control lines and mitigating hazards around the burned area.

Cal Fire officials said that fire apparatus had been moved off the freeway to prevent further traffic disruptions. While the blaze was contained, crews continued to construct control lines and assess the risk of re‑ignition. The agency’s update indicated that the fire’s forward progress had stopped, but that work on containment lines was ongoing.

The San Diego County Sheriff’s Department issued evacuation warnings and orders for structures threatened by the fire. A shelter‑in‑place order was also issued for nearby buildings. The orders were lifted less than an hour later, by 3 p.m., after the fire’s threat had been reduced.

The California Highway Patrol (CHP) Border Communications Center closed two lanes of I‑15 and the Mission off‑ramp while crews worked to extinguish the fire. All lanes were reopened and the Sig Alert was canceled by 3:30 p.m. At 4 p.m., CHP Oceanside reported that Sterling View Drive and Old Highway 395 remained closed to allow fire crews access to the brush‑fire area.

The burned hillside is visible from the freeway and has been described as a dark patch against the surrounding vegetation. The incident did not result in any reported injuries or property damage beyond the burned brush.

Fallbrook lies just east of Marine Corps Base Camp Pendleton and is known for its avocado groves. The I‑15 corridor is a major north‑south artery connecting San Diego to the Inland Empire and beyond. Wildfire risk in California remains high during the summer and fall months, and incidents like the Mission 2 Fire underscore the need for rapid response and public safety measures.

Cal Fire continues to monitor the area and will keep the public updated on any changes in containment status or traffic conditions. The incident is considered contained, and no further disruptions to I‑15 traffic are expected at this time.
