WEST RANCHO DOMINGUEZ, Los Angeles County, Calif., Sept. 22, 2026 — Two people were hurt early Tuesday morning, September 22, when a sedan collided with a tractor-trailer near El Segundo Boulevard and San Pedro St and became lodged beneath it.
The California Highway Patrol said a white Hyundai sedan struck the tractor-trailer around 12:33 a.m. and wedged underneath the larger vehicle. The driver of the sedan and another passenger, whose location at the time of impact was not specified, were both taken to a hospital.
Los Angeles County Fire Department crews responded to free the sedan from beneath the trailer and load at least one injured person into an ambulance, footage from the scene showed. The conditions of the two injured people have not been released.
The CHP has not said what led up to the collision, but they are investigating the incident. No further details on the cause were immediately available.
We wish the injured a complete and speedy recovery.
How Investigators Piece Together an Underride Crash
When a passenger car ends up wedged beneath a tractor-trailer, reconstructing what happened takes more than a quick look at the wreckage. Investigators typically measure skid marks, photograph the point of impact, and document how far the smaller vehicle traveled underneath the trailer before it stopped. That physical evidence helps establish speed, angle of approach, and whether the trailer's underride guard performed as intended.
Toxicology results, when ordered, can take weeks to come back from a lab, and a full mechanical inspection of both vehicles can take just as long. Agencies also wait to release identifying details until next of kin have been notified, which is one reason early reports on crashes like this often withhold names even after injuries are confirmed.
According to the National Highway Traffic Safety Administration, 5,472 people were killed in traffic crashes involving large trucks in 2023. That volume of cases is part of why final reports on truck-involved collisions move slowly: reconstruction specialists and lab resources are scarce, and a detailed investigation and the report that follows take time.
Frequently Asked Questions
Why are these collisions particularly dangerous for the smaller vehicle?
A tractor-trailer's trailer bed sits higher off the ground than a sedan's crumple zones and safety cage, so in some impacts the car can slide underneath it rather than being stopped by the front-end structure designed to absorb a crash.
What should someone do immediately after being in a crash like this?
Call 911, stay as still as possible if you're hurt, and let paramedics assess you even if you feel fine at first. Move to a safe spot away from traffic only if you're able, and get contact information for any witnesses before they leave the scene.
