Ontario, CA (June 10, 2026) – A multi-vehicle collision was reported on Wednesday morning on westbound Interstate 10 near Archibald Avenue. The crash involved at least three vehicles, including a white Lexus sedan, a white van, and a box truck.
The box truck overturned during the collision and came to rest on its side, blocking multiple lanes of the freeway, and the white van was also disabled, blocking the right lane in front and the second and third lanes. A sig-alert was issued covering lanes three, four, and five on the eastbound side near Vineyard Avenue for approximately 30 minutes.
Emergency units were called to the scene, and a medium-duty tow truck was requested to handle the overturned box truck, which measured roughly 25 feet long and weighed approximately 10,000 pounds. No confirmed injury information was included in the initial report on the accident.
Further details about those involved in the wreck had not been made public at the time of this report. Investigators are still working to piece together the full sequence of events leading up to the collision.
We hope that everyone involved is safe and receives any care they may need.
What Typically Happens After a Commercial Truck Overturn on a California Freeway?
When a box truck or commercial vehicle overturns on a freeway, the recovery process is more involved than a standard tow. Specialized equipment is usually needed to right the vehicle before it can be removed, which is why medium- or heavy-duty tow trucks are dispatched separately from those handling passenger cars. The size and weight of commercial vehicles mean that clearing the road can take significantly longer than in a typical two-car crash.
Sig-alerts in California are issued when a lane blockage is expected to last 30 minutes or more, and they notify drivers through highway signs and traffic apps. When multiple lanes are blocked by a large vehicle, the ripple effect on surrounding traffic can extend for several miles. Drivers are generally advised to seek alternate routes as soon as a sig-alert is posted.
Overturned commercial vehicles may also trigger a separate review of the truck’s load, mechanical condition, and driver records, depending on what investigators find at the site.
