RICHMOND, Contra Costa County, Calif., Oct. 28, 2026 — Seven vehicles collided Tuesday morning, October 27, on westbound I-580 near Harbour Way, according to the California Highway Patrol. The crash left a red Mazda sedan facing the wrong way in a travel lane and blocked multiple lanes of traffic.
The CHP said the collision began as a four-vehicle wreck shortly before 7 a.m., involving a white Tesla, a white pickup truck and a Mini Cooper among the vehicles. A gray Buick was reportedly pulled into the crash as well, bringing the total to seven vehicles involved, per dispatch updates.
A driver reported being trapped inside the Tesla, though that person reportedly declined ambulance transport and it was not immediately clear whether the car could still be driven. The red Mazda, found facing the wrong direction in a center lane, was also reported as a no-injury collision. No other injuries were mentioned in the CHP's initial log, though the agency's classification of the incident shifted at one point to reflect a request for medical response.
Units reported fire involvement in at least one vehicle. The CHP closed three lanes to deal with the wreckage, requested backup units to hold the closure, and tow trucks including one identified as responding from a local company handled vehicle removal. Authorities have not released a cause for the crash or said whether anyone will face charges.
The investigation remains open. The CHP has not detailed how the Mazda came to be traveling against traffic or whether that vehicle's movement triggered the pileup.
We are hoping for the best for everyone involved and their families.

Frequently Asked Questions
Does alcohol play a role in wrong-way crashes?
Alcohol impairment is a factor in a large share of wrong-way crashes nationally, since it affects a driver's ability to judge direction and react to signage, though investigators have not said whether that was a factor here.
What causes wrong-way crashes?
Common causes include driver impairment, confusion at interchanges or off-ramps, missed or obscured signage, and nighttime or low-visibility conditions that make it harder to notice oncoming headlights.
Why are wrong-way crashes often more serious than other collisions?
Because the vehicles are typically closing on each other rather than traveling the same direction, the combined speed at impact tends to be much higher, which usually means more severe damage and injury than a same-direction rear-end or sideswipe.
What to Do After a Multi-Vehicle Crash in Richmond, CA
If you're involved in a pileup on a freeway like I-580, try to move to the shoulder only if your vehicle is drivable and it's safe to do so; otherwise stay put with hazard lights on until help arrives. Call 911 even if injuries seem minor, since adrenaline can mask pain from whiplash or internal injury that shows up hours later. Get checked by a medical provider the same day if possible, and ask responding officers how to get a copy of the incident report for insurance purposes. Exchange insurance and contact information with other drivers when it's safe, and take photos of vehicle positions and damage before cars are towed. Richmond drivers dealing with the aftermath of a multi-vehicle wreck should also keep records of any missed work or medical visits in the days that follow.
