Fatal Multi‑Vehicle Crash Involving Big Rig Shuts Southbound I‑5 in Boyle Heights; One Dead, Multiple Injured

Overview of the December 28, 2025 Collision

A devastating multi-vehicle crash involving a big rig on the southbound Golden State (5) Freeway in Boyle Heights, Los Angeles, early Sunday morning, December 28, 2025, left one person dead and sent multiple others to area hospitals. According to the California Highway Patrol (CHP), the collision occurred at approximately 5:10 a.m. just south of 4th Street when a tractor-trailer impacted several vehicles, triggering a chain reaction across multiple lanes.

Los Angeles Fire Department (LAFD) officials reported that at least one vehicle caught fire following the impact. A physical rescue was requested at the scene to assist individuals trapped in damaged vehicles. CHP noted that all southbound lanes were closed at about 5:22 a.m. while first responders worked to secure the area, assess injuries, and remove disabled vehicles. Nine vehicles were reported to have sustained significant front-end damage. It was not immediately known whether the big rig was loaded at the time of the crash.

Authorities stated that 15 people were evaluated at the scene and 10 patients were transported to local hospitals, including some with moderate injuries who were taken to Adventist Health White Memorial Hospital. The cause of the crash remains under investigation.

Emergency Response and Traffic Impacts

Major freeway incidents in dense urban corridors like Boyle Heights require rapid, coordinated response. In this incident, fire crews extinguished the vehicle fire and performed extrication where needed, while CHP managed traffic control, lane closures, and initial fact gathering. Caltrans typically assists with cleanup and roadway inspection before lanes can safely reopen.

The total closure of southbound I‑5 at this key connector likely caused significant delays during the morning hours, with traffic diverted to nearby arterials and freeways. Drivers in the area were advised to seek alternate routes until the scene could be cleared and investigators completed initial documentation.

This devastating crash on southbound I-5 has left one family mourning a sudden loss and many others facing painful recoveries. Multi-vehicle collisions involving commercial trucks can escalate rapidly, leaving victims with life-altering injuries and unanswered questions.
