WALNUT, Los Angeles County, Calif., Nov. 10, 2026 — At least one person was hurt in a multi-vehicle crash on Monday morning, November 9, on westbound State Route 60 at South Lemon Avenue, according to the California Highway Patrol.
The crash was reported just west of Lemon Avenue on the westbound side of SR-60, involving five vehicles, a Hyundai, a Toyota RAV4, a Dodge Ram, a Mercedes and a sedan. Initial reports described an unknown-injury collision, which the CHP later updated to confirm at least one person needed an ambulance. That patient was reported transported by the Los Angeles County Fire Department.
A caller at the scene reportedly described a related slowdown in the area, and the CHP log noted a possible separate collision nearby, though that has not been confirmed as connected to this crash. One disabled vehicle was also reported blocking the carpool lane, and authorities requested a traffic break near Grand Plaza to manage the backup. Tow trucks were called to clear multiple vehicles from the roadway as all parties were moved to the right shoulder.
The CHP continues to look into what led to the crash. We hope those who were hurt recover fully.

Frequently Asked Questions
Why do chain-reaction crashes like this happen?
They usually start when one vehicle slows or stops suddenly, usually in heavy traffic, and following drivers don't have enough space or time to react before striking it or each other.
How can drivers avoid getting caught in a pile-up?
Leaving extra following distance, scanning well ahead for brake lights, and easing off the gas early when traffic bunches up can give drivers more room to stop safely.
What should I do if I'm stopped near a crash on the highway?
Stay inside the vehicle if it's not blocking a lane, turn on hazard lights, and wait for a traffic break or officer direction before trying to move around the scene.
How does fog or low visibility contribute to pile-ups?
Reduced visibility shortens the distance drivers have to spot a hazard, which can turn a single stopped vehicle into a chain of rear-end collisions before anyone has time to brake.
