CLAREMONT, Los Angeles County, Calif., Oct. 28, 2026 — A multi-vehicle crash blocked lanes on eastbound Interstate 10 in Claremont Tuesday night, October 27, and prompted an ambulance to be sent to the scene, according to the California Highway Patrol.
The collision was reported shortly before 8:40 p.m. just west of Indian Hill Boulevard, the CHP said. A gray Toyota Corolla and a blue Toyota 4Runner were initially reported involved, and a third vehicle, described as a gray sedan, was added to the call within minutes. The crash blocked the number one lane and at one point halted all lanes of traffic in the area, dispatch logs show.
Officers later described the vehicles involved as a silver Lexus ES300 and two other cars, both reportedly small sedans, with one leaking fluid at the scene. The discrepancy between the earlier and later vehicle descriptions was not resolved in the public dispatch record, and it is unclear whether additional vehicles were pulled into the chain of impacts. The CHP upgraded the incident from a collision of unknown injury severity to one with injuries and an ambulance en route, according to dispatch notes.
Investigators said one of the parties left the scene before officers arrived, and the case was being handled as a misdemeanor hit-and-run under California law. Tow crews were called to clear the vehicles, with one company telling dispatchers it could manage both tow jobs with a single truck. No further details on injuries or the drivers involved had been released as of Wednesday morning, and the CHP's investigation remains open.
We are hoping for the best for those involved as more details come in.

Frequently Asked Questions
Why is distracted driving so dangerous?
Taking your eyes or attention off the road for even a few seconds at highway speed means traveling a significant distance with little or no reaction time if traffic ahead slows or stops.
How do weather and road conditions contribute to crashes?
Wet pavement, debris, glare, and low visibility all cut down the margin drivers have to react, especially in heavier traffic like a freeway corridor.
What should I do immediately after a car accident?
Move to a safe spot if possible, check for injuries, call 911, and exchange information with other drivers. Even if injuries seem minor, it's wise to get checked by a medical provider, since some symptoms appear later.
What to Do After a Car Accident in Claremont, CA
If you're involved in a crash on a freeway like I-10, try to get your vehicle to the shoulder if it's drivable and safe to do so, then turn on hazard lights and stay inside if traffic is still moving nearby. Call 911 and wait for officers to arrive before exchanging information, especially if another driver seems unwilling to stop. Take photos of vehicle positions and damage if you're able, and get contact information for any witnesses. Afterward, seek a medical evaluation even for minor aches, and keep copies of the CHP incident report and any paperwork for your insurance company.
