DOWNEY, Los Angeles County, Calif., Nov. 11, 2026 — A chain-reaction crash involving at least three vehicles injured at least one driver early Tuesday morning, November 10, on southbound Interstate 5 near Lakewood Boulevard, according to the California Highway Patrol.
The CHP said the collision was first reported as a vehicle striking a guardrail on southbound I-5 just south of Lakewood Boulevard. A second vehicle then reportedly struck the first, and radio traffic described the initial impact as a head-on crash involving a car and another vehicle of unknown description. One log entry also referenced a white Peterbilt semi truck versus a dark-colored sedan on the right shoulder.
The crash blocked the left lane and then all southbound lanes near Slauson Avenue before traffic was reported moving again with a break near Paramount Boulevard. A reporting party later told dispatchers it was a three-vehicle collision. CHP units requested tow trucks for at least three disabled vehicles, including a Hyundai Palisade with front axle damage, a Mazda CX-30 that was immobile on its front wheels, and a gray SUV described as having major front and rear end damage.
The CHP also logged the incident as a possible hit-and-run under Vehicle Code 20002, a misdemeanor offense, though it did not say which vehicle or driver was involved. A reporting party who left the scene told dispatchers she had arranged a tow for her car.
The crash remains under investigation by authorities. We wish the injured a complete recovery.

Frequently Asked Questions
What typically causes a chain-reaction, multi-vehicle crash like this one?
These pile-ups usually start when one vehicle strikes a fixed object or another car, then following traffic can't stop in time, especially in low visibility or heavy overnight truck traffic.
Why do these crashes keep happening on busy freeway stretches?
Lane closures from an initial crash usually create sudden stops for drivers who aren't expecting them, which can trigger a second or third collision before responders arrive.
What should drivers do if traffic is stopped ahead on the highway?
Slow down as early as possible, turn on hazard lights, and leave extra space, since rear-end strikes into stopped traffic are a common way these incidents grow.
How can drivers lower the chance of getting caught in one?
Keep a longer following distance in the dark or in truck-heavy lanes, and watch for brake lights well ahead instead of relying on the car directly in front.
