OAKLAND, Alameda County, Calif., Sept. 25, 2026 — Two people were hurt in a string of crashes early on Thursday morning, September 24, on southbound I-880 near 66th Avenue, according to the California Highway Patrol.
The chain of collisions began when a car struck unknown debris in the roadway. Additional vehicles then collided in the same area, including a car and a big rig, and separately a white sedan and a pickup truck, according to dispatch logs. A white Dodge Ram was also reported involved on the right shoulder.
One person suffered a minor injury, and another, a tow truck operator who responded to the scene, reported a bloody nose after being struck. Emergency crews requested ambulance response for injuries and closed the number four lane while a tow truck cleared a heavily damaged pickup from the shoulder.
Investigators say one of the drivers left the scene of a portion of the crash, a possible misdemeanor hit-and-run, before all parties were confirmed accounted for and sent on their way. The CHP has not released names of those involved, and the full sequence of the multiple collisions remains under review.
We hope everyone who was hurt makes a full and speedy recovery.
Where Multi-Vehicle Pile-Ups Tend to Start
Multi-vehicle crashes like the one on I-880 usually begin with something small: a dropped load, a patch of debris, a stalled car in a travel lane. On a freeway carrying steady early-morning traffic, that first obstacle can trigger a cascade of braking and lane changes that reaches back for hundreds of feet before anyone even sees what caused it.
Stretches of freeway near merge points, on-ramps, and lane reductions concentrate this kind of crash because vehicle speeds vary the most there. Drivers merging from a ramp are usually moving slower than through traffic, and heavy vehicles like big rigs need more distance to react to sudden slowdowns. When one vehicle brakes hard, following drivers who are too close or distracted have little space to stop, and a single incident becomes several.
According to the National Highway Traffic Safety Administration, 365 large-truck occupants were killed in multi-vehicle crashes involving large trucks in 2023. Crashes that begin with debris or a disabled vehicle in a travel lane are especially prone to growing into multi-car incidents, since visibility and reaction time both shrink in the seconds after the first impact.
Frequently Asked Questions
Why does following distance matter so much on freeways?
More space between vehicles gives a driver time to react if traffic ahead brakes suddenly. On high-speed roads, even a few extra car lengths can be the difference between stopping safely and rear-ending another vehicle.
Do secondary crashes happen usually after an initial wreck?
Yes. Once a crash blocks a lane or debris scatters across the roadway, oncoming traffic sometimes has little warning, and additional vehicles can strike the wreckage or each other before the scene is secured.
Why are multi-vehicle crashes hard to investigate?
Investigators usually have to sort out which impact happened first, how many vehicles were involved, and whether one crash caused another. Conflicting driver accounts and scattered debris can complicate that timeline.
What to Do After a Multi-Vehicle Crash in Oakland, CA
If you're involved in a chain-reaction crash, try to move to a safe location off the travel lanes if your vehicle is drivable, and turn on hazard lights to warn other traffic. Call 911 to report injuries and request medical evaluation, even if you feel fine at first, since some injuries take hours to show symptoms.
Get contact and insurance information from other drivers if it's safe to do so, and note anything unusual about the roadway, such as debris or poor lighting. A written CHP or police report can help clarify what happened once all vehicles involved are identified.
