OCEANSIDE, San Diego County, Calif., Nov. 12, 2026 — Two vehicles collided on northbound Interstate 5 near Las Flores Drive on Wednesday afternoon, November 11, according to the California Highway Patrol. The crash was initially logged as a collision with unknown injuries before being updated to a confirmed-injury crash.
The collision blocked the number one lane on northbound I-5 north of Las Flores Drive, close to the State Route 78 interchange near Vista Way. Descriptions of the vehicles involved were not released. A short time later, a report noted a vehicle stopped on the right shoulder of northbound I-5 near the same location, though it was not clear if it was connected to the original crash.
The extent of any injuries was not specified in the CHP's public log. A tow truck was requested to clear the scene, and dispatch notes show at least one towing company responding to handle the vehicles. An earlier tow request tied to the incident was later canceled.
No further details on the cause of the crash have been released. The CHP has not said whether speed or any other factor contributed, and the investigation appeared to still be active as of the latest log entries.
We wish the injured a complete and speedy recovery.

Where do most traffic crashes happen?
Crashes are common at interchanges, on-ramps, and areas where lanes merge or traffic slows suddenly, conditions similar to those near highway interchanges like the I-5/SR-78 area.
What injuries are typically reported in two-vehicle highway crashes?
Common injuries include whiplash, cuts and bruises, and in harder impacts, broken bones or head injuries. Severity usually depends on speed and the angle of impact.
