GILROY, Santa Clara County, Calif., Nov. 9, 2026 — Four vehicles collided on northbound US-101 near State Route 25 on Sunday morning, November 8, according to the California Highway Patrol. The crash left at least one driver with injuries serious enough that an ambulance was requested to the scene.
The collision was reported shortly before 11 a.m. just north of the SR-25 interchange. Vehicles involved reportedly included a sedan, a minivan, an SUV and another passenger car, based on descriptions relayed by callers at the scene. One driver told dispatchers her airbags had deployed and her vehicle was no longer drivable, and she said she did not have money to pay for a tow.
The CHP initially logged the incident as a crash with unknown injuries before upgrading it to a call for medical response. Dispatchers also noted a traffic hazard in the roadway as crews worked to clear the vehicles, which had come to rest blocking lanes before being moved to the shoulder and center divider. The extent of injuries to those involved had not been detailed as of this writing.
No information on what caused the chain-reaction crash has been released, and the CHP has not said whether speed or any other factor played a role. The incident remains under investigation.
Our thoughts are with those who were injured, and we wish them a full recovery.

Frequently Asked Questions
Why are multi-vehicle crashes usually harder to sort out than two-car wrecks?
Investigators have to figure out the order each vehicle struck another, which usually means reviewing damage patterns, witness accounts, and sometimes video from nearby cameras before assigning any responsibility.
What typically triggers a chain-reaction pile-up like this one?
These crashes commonly start when one vehicle slows or stops suddenly, usually due to congestion, a stall, or an earlier collision, and following drivers don't have enough space or time to react before striking the cars ahead.
Is there anything drivers can do if traffic ahead suddenly backs up on a highway?
Leaving extra following distance and watching brake lights several cars ahead gives drivers more time to slow gradually instead of braking hard at the last second, which can lower the odds of being pulled into a pile-up.
