One person was killed and two others were taken to hospital early on Sunday, November 1, 2026, in a multi-vehicle rollover crash on the northbound San Diego (405) Freeway in Sherman Oaks, Los Angeles, that shut down every northbound lane for about five hours, the California Highway Patrol said in reports carried by Los Angeles outlets. The crash was reported at about 1:45 a.m. on the northbound 405 near the Ventura (101) Freeway interchange, on a rain-slick stretch of one of the busiest freeway junctions in the San Fernando Valley.

What happened on the northbound 405

According to the California Highway Patrol account carried by MyNewsLA, the collision involved multiple vehicles on the northbound side of the 405 near the 101 interchange, and one person was ejected from a vehicle that rolled over. That person was pronounced dead at the scene. Two other people were taken to a hospital; their conditions and identities had not been released in Sunday's reports. KTLA, in its own on-scene report from the freeway on Sunday morning, likewise reported at least one person dead after the overnight multi-car crash on the 405 in Sherman Oaks, and Los Angeles Daily News coverage indexed the same 1:45 a.m. fatal multi-car crash and shutdown.

The reports available on Sunday did not say how many vehicles were involved in total, what type of vehicles they were, or what set the rollover in motion. In fatal freeway crashes in Los Angeles, the county medical examiner normally releases the name of the person killed only after the family has been notified, and the Highway Patrol's full account — the sequence of impacts, any citations, and whether speed, impairment or the wet road played a role — comes only after investigators finish at the scene and review the vehicles.

Five hours of closed lanes and a SigAlert

The crash and the emergency response closed all northbound lanes of the 405 at Sherman Oaks for about five hours, with a SigAlert in effect, MyNewsLA reported. A SigAlert is the California Highway Patrol's traffic alert for an unexpected incident expected to cause significant delays — in practice, a full directional closure of the 405 in the Sepulveda Pass corridor pushes Valley traffic onto the 101, Sepulveda Boulevard and surface streets, and Sunday-morning drivers heading from the Los Angeles basin into the San Fernando Valley, or onward toward the 5 and 118 freeways, faced the detours while crews worked.

Where it happened: the 405 at the 101, in the Sepulveda Pass corridor

The Sherman Oaks stretch of the 405 is the San Fernando Valley end of the Sepulveda Pass, the mountain crossing that carries the San Diego Freeway between the Los Angeles basin and the Valley. Its junction with the Ventura (101) Freeway, just south of Ventura Boulevard, is one of the most heavily used interchanges in California — the route Valley residents use toward downtown Los Angeles, Los Angeles International Airport and the Westside, and a corridor long-haul and local trucks use to cross the city. A fatal crash and a five-hour full closure at that junction is therefore a regional traffic event, not just a neighbourhood one, even in the small hours of a Sunday.

Rain on a Halloween-weekend night in Los Angeles

MyNewsLA described the freeway as rain-slick at the time of the crash. Rain matters on Los Angeles freeways for a practical reason drivers in the region know well: the first sustained rain after dry weeks lifts oil and dust on the pavement, stopping distances grow, and overnight speeds on the 405 through the Sepulveda Pass stay high even as visibility drops. Investigators have not said rain caused this crash, and this report does not claim it did — but the wet road is part of the confirmed scene the Highway Patrol will be weighing, alongside speed, lane changes and the possibility of impairment on a Halloween-weekend night, when Los Angeles roads carry late crowds heading home.

What happens next

The California Highway Patrol will complete its investigation of the crash — documenting the scene, examining the vehicles, and interviewing the surviving drivers and any witnesses — and is expected to release the fuller account that Sunday's first reports did not contain: how many vehicles were involved, how the rollover happened, and whether any driver faces a citation or charges. The Los Angeles County medical examiner will identify the person who died once the family has been notified. Until those details are out, the confirmed picture stays narrow: a multi-vehicle rollover at 1:45 a.m. on a rain-slick northbound 405, one person ejected and killed, two people in hospital, and a five-hour shutdown of one of Los Angeles' most important freeway junctions. This story will be updated when the Highway Patrol publishes its findings.
