MILPITAS, Santa Clara County, Calif., Oct. 1, 2026 — Three vehicles collided on Tuesday night, September 29, on northbound I-880 near Dixon Landing Road. At least one person was reported injured, including a child who was in one of the vehicles.
The California Highway Patrol said a gray Kia Soul, a silver Toyota and a black Volkswagen Jetta were involved in the crash. Radio traffic from the scene indicated the Toyota's occupants included a child and requested medical aid, and a report described the Jetta as the lead vehicle struck from behind, with the possibility of additional vehicles involved not yet confirmed.
An ambulance was requested for the Toyota, which the agency said sustained moderate front-end damage. It was not immediately clear how many people were taken to hospitals or the extent of any injuries. The crash blocked at least one travel lane, and authorities later reported all lanes reopened once the roadway was cleared.
A tow truck was called to remove at least one of the vehicles from the scene. The California Highway Patrol has not released a cause for the collision, and the incident remains under investigation.
We wish those injured a full recovery.
Multi-Vehicle Pileups by the Numbers
According to the National Highway Traffic Safety Administration, 2,979 passenger-car occupants were killed in two-vehicle crashes involving a passenger car and a light truck in 2023. That figure reflects how mismatched vehicle sizes and weights shape outcomes even in crashes involving only two vehicles, a dynamic that becomes more complicated once a third or fourth vehicle gets pulled into the same chain of impacts.
Multi-vehicle collisions on freeways usually start as a single rear-end or lane-change crash that stops or slows traffic, then draws in trailing vehicles that don't have time to react. Speed differences at the moment of impact, not just total speed, tend to determine which occupants face the greatest risk of serious injury.
Investigators working these scenes typically have to sort out the sequence of impacts, which can take longer than a single-vehicle crash to untangle. Damage patterns, witness accounts, and vehicle positioning all help determine which collision triggered the pileup and which were secondary.
Frequently Asked Questions
What should I do if I'm stopped near a crash on the highway?
Turn on hazard lights, stay buckled in if it's safe to remain in the vehicle, and move as far right as possible. If you must exit, get behind a guardrail or barrier away from traffic lanes.
How does fog or low visibility contribute to pile-ups?
Reduced visibility shortens the time drivers have to react to slowed or stopped traffic ahead, which is part of why chain-reaction crashes usually involve several vehicles arriving at the scene within seconds of each other.
Why does following distance matter so much in freeway traffic?
A longer following distance gives a driver more time to brake or steer around a hazard. On high-speed roads, even a small cushion can be the difference between stopping safely and becoming part of a multi-vehicle crash.
Are secondary crashes common after an initial wreck?
Yes. Vehicles that slow or stop to avoid the first collision can be struck by traffic arriving behind them, which is why responders move vehicles to the shoulder and open lanes as quickly as conditions allow.
What to Do After a Multi-Vehicle Crash in Milpitas, CA
If you're involved in a multi-vehicle crash, check on passengers and nearby occupants before assessing vehicle damage. Call 911 if anyone is hurt, and move to the shoulder or a safe area if your vehicle is drivable and it's safe to do so.
Even when injuries seem minor, it's worth getting checked by a medical provider afterward since some injuries, especially to the neck and back, aren't immediately obvious. Keep a copy of the CHP incident report once it's available, and photograph vehicle positions and damage if you're able to safely do so at the scene.
