Commerce, CA (October 15, 2025) – A multi-vehicle crash involving a semi-truck caused an oil spill and major traffic delays Wednesday morning on the 5 Freeway in Commerce, according to the California Highway Patrol.
Accident Details: The collision occurred around 4:30 a.m. on the southbound side of the 5 Freeway near Washington Boulevard. CHP officials said several vehicles, including a big rig, were involved in the crash, which resulted in a diesel and oil spill across multiple lanes. Emergency crews closed all southbound lanes while hazmat teams worked to contain the spill and clear debris from the roadway. At least one person was transported to a local hospital with minor injuries. Traffic was diverted off the freeway at Telegraph Road and remained backed up for several miles through the early morning commute.
Investigation: CHP officers are investigating the sequence of impacts and the cause of the initial crash. They are reviewing skid marks, vehicle positions, and statements from involved drivers to determine whether weather, speed, or following distance played a role. Caltrans and environmental cleanup crews assisted in managing the oil spill, which required several hours of containment and removal before lanes reopened.
Legal Considerations: Multi-vehicle collisions that involve commercial trucks and hazardous material spills can present complex liability issues. Investigators and insurers will assess whether proper safety precautions were followed by the truck driver and carrier, including vehicle maintenance, cargo handling, and compliance with environmental regulations. Injured motorists may pursue compensation for medical bills, lost wages, and property damage if negligence is established.
This was a chaotic and stressful morning for drivers in Los Angeles County. I hope the injured individual recovers quickly and that crews are able to restore traffic safely.
