On the morning of June 20, 2026, a red big rig crashed through the center divider on Interstate 210 near Irwindale Avenue, crossing from the eastbound lanes into the westbound side. According to CHP logs, the truck jackknifed, struck the guardrail and center divide, and hit two other vehicles. Authorities upgraded the incident to a major-injury collision, prompting a large response from fire crews, CHP, Irwindale police, and Caltrans. Multiple lanes and carpool lanes in both directions were closed, and a SigAlert with unknown duration was issued. Officials also reported dangerous secondary behavior, including a white BMW SUV and other vehicles driving the wrong way on the shoulder and through a divider opening. Some lanes were later reopened as crews worked to clear the scene and assess the damage.
Accident News Report
A big rig crashed through the center divider on Interstate 210 in Irwindale on Saturday morning, blocking multiple lanes in both directions and damaging freeway infrastructure, according to California Highway Patrol logs.
The collision was reported around 8:55 a.m. on June 20, 2026, on I-210 near the Irwindale Avenue on-ramps. Dispatch notes indicate a red big rig traveled from the eastbound lanes through the concrete center divide into the westbound lanes, striking the guardrail and center divider. The truck jackknifed and was reported to have hit two other vehicles.
CHP reclassified the incident to a major-injury traffic collision with emergency medical response requested. Fire crews were reported on scene on the westbound side, and all eastbound traffic was initially stopped while responders worked. High-occupancy vehicle lanes and several general-purpose lanes in both directions were blocked, and cones were used to shut down portions of the roadway.
Irwindale police responded to help close the northbound and southbound Irwindale Avenue on-ramps to westbound I-210, and officials requested Caltrans to assist with a hard closure and traffic control. CHP air support reported extensive guardrail damage on eastbound I-210 and issued a SigAlert with an unknown duration affecting both directions of the freeway between State Route 605 and Irwindale.
As traffic backed up, officers reported vehicles attempting to drive the wrong way on the shoulder and through an opening in the center divider, including a white BMW SUV that made a U-turn onto the right shoulder and began traveling against traffic. Crews gradually reopened some eastbound lanes, but carpool lanes remained closed while the scene was cleared and the investigation continued. Details on the number and severity of injuries, including any fatalities, had not been fully released in the log excerpts.
Important Details
What California law says after a truck accident
Why commercial vehicle cases are different
A collision involving a commercial truck or bus is not simply a larger car collision. Commercial carriers operate under federal and state safety regulations covering driver hours of service, vehicle inspection and maintenance, driver qualification, and cargo securement. A violation of those rules can bear directly on how the collision happened.
These cases also involve records that do not exist in an ordinary collision: electronic logging device data, engine control module data, maintenance and inspection files, driver qualification files, dispatch records, and in many vehicles onboard camera footage. Federal rules require carriers to keep much of this material only for a limited time. Driver vehicle inspection reports must be retained for three months, records of duty status and the supporting documents behind them for six months, and annual inspection reports for fourteen months. The logging device on the truck itself typically holds only the current day and the previous seven days.
Other material that often matters most, including engine control module data, onboard camera video, and raw location data, carries no federal retention period at all and is overwritten on the carrier’s own cycle.
For that reason, requests to preserve evidence are often sent to the carrier and its insurer early. Responsibility may also extend beyond the driver to the motor carrier, a maintenance contractor, or whoever loaded the cargo.
Reporting requirements after a California collision
California imposes reporting duties on drivers that are separate from any insurance claim.
A report must be filed with the DMV on form SR-1 within ten days of a collision that caused any injury, any death, or more than one thousand dollars in property damage to any one person. This duty applies regardless of fault, applies even when police responded and wrote their own report, and is not satisfied by notifying an insurance company. With current repair costs, most collisions that involve a body shop meet the damage threshold.
A separate rule covers collisions causing injury or death. The driver must make a written report to the California Highway Patrol, or to the city police department where the collision happened in a city, within twenty four hours. The statute states this duty for every injury or fatal collision. In practice, where officers responded and completed a report at the scene, that report generally satisfies the agency’s need, but a driver who assumes this without confirming it is relying on practice rather than on the text of the law.
Missing the DMV deadline can lead to suspension of driving privileges, an outcome unrelated to who caused the collision.
