CLAREMONT, Los Angeles County, Calif., Oct. 31, 2026 — At least one person was hurt early Saturday morning, October 31, when a series of vehicles struck tire debris and a disabled semi-truck on eastbound Interstate 10 near Indian Hill Blvd, according to the California Highway Patrol.
The chain-reaction crash began when a semi-truck tire came apart in the number one and two lanes west of Indian Hill Blvd, CHP dispatch logs show. Multiple vehicles reportedly struck the debris in the dark, and some of the disabled cars and the resulting pileup extended backward toward Towne Ave and Garey Ave. Vehicles involved reportedly included a Tesla Model 3, a Dodge Charger, a Kia Sportage, a Ford Mustang and the semi-truck itself, among others. Early radio traffic put the number of vehicles involved anywhere from about 7 to 10.
A caller first reported no injuries, but CHP's log was later updated to reflect an injury crash, with paramedics from the Los Angeles County Fire Department requested to the scene. One vehicle, a Ford Mustang, reportedly struck debris in the roadway after the initial collisions were already blocking lanes. Several vehicles were described as inoperable, and tow trucks were called to multiple cars, including the Tesla, as crews worked to clear wreckage blocking the middle and slow lanes.
The CHP has not released the condition of the person hurt, nor said how the tire debris initially separated from the truck. The incident remains under investigation.
We hope everyone involved is okay, and we will share more as details are confirmed.

Frequently Asked Questions
What are a truck's blind spots, and why do they matter in crashes like this?
Large trucks have wide blind spots along both sides, behind the trailer and directly in front of the cab. Vehicles traveling or stopping in these zones may not be visible to the driver, which can contribute to collisions, especially in low light or heavy traffic.
What is an underride crash?
An underride crash happens when a smaller vehicle slides partially or fully beneath a truck's trailer during a collision, usually because the trailer sits higher off the ground than a car's crumple zones. These crashes can cause severe damage even at moderate speeds.
What usually causes large-truck accidents like this one?
Common factors include road debris, tire failures, driver fatigue, mechanical problems and sudden braking in heavy traffic. Investigators typically look at vehicle maintenance records and road conditions when sorting out what happened.
How can drivers stay safer when sharing the road with trucks?
Giving trucks extra following distance, avoiding lingering in blind spots and watching for debris in travel lanes can help drivers react sooner if conditions change suddenly.
