SOUTH LOS ANGELES, Los Angeles County, Calif., Oct. 1, 2026 — A multi-vehicle crash with injuries blocked the slow lane on southbound I-110 near Florence Avenue in South Los Angeles on Wednesday morning, September 30, according to the California Highway Patrol.
The collision was reported shortly after 10:20 a.m. just north of Florence Avenue and reportedly involved three to four vehicles, including a gray Chrysler 300, a silver Honda Civic and a black Nissan Sentra. All three were reported resting on the shoulder.
The agency's call log shows the incident was initially logged as a collision with unknown injuries before being upgraded to a collision with a confirmed injury requiring an ambulance. A tow was also requested for at least one vehicle described as having major front-end damage.
Caltrans Freeway Service Patrol crews responded to the scene alongside CHP unitss. FSP closed out its portion of the response shortly before 11:10 a.m., and the CHP incident was closed by 11:16 a.m. Wednesday, records show.
The collision remains under investigation. We wish those injured a full recovery.
Multi-Vehicle Crashes on Freeways by the Numbers
According to the National Highway Traffic Safety Administration, an estimated 6,138,359 police-reported traffic crashes occurred in 2023. Many of these involve three or more vehicles, particularly on high-volume urban freeways where traffic bunches up near interchanges and merge points, creating chain-reaction collisions when one driver brakes suddenly.
Freeway segments near major interchanges, like the stretch of I-110 through South Los Angeles, see a steady volume of multi-car pileups tied to congestion, lane changes, and following too closely at highway speeds. When a lead vehicle slows or stops unexpectedly, the vehicles behind often don't have enough room to react, and the result is a cascading series of impacts instead of a single two-car crash.
These incidents frequently shut down one or more lanes for cleanup and towing, even when injuries are moderate, because of debris, fluid spills, and vehicles left blocking active lanes. That's part of why response from both CHP and Freeway Service Patrol crews is common on busy corridors, clearing lanes quickly matters as much as treating anyone hurt.
Frequently Asked Questions
What usually causes multi-vehicle freeway crashes like this one?
Sudden braking, following too closely, and lane changes in heavy traffic are common triggers. Once one vehicle stops or slows abruptly, trailing cars often cannot stop in time, and the collision spreads to additional vehicles.
How does speed change the outcome of a crash like this?
Higher speeds mean longer stopping distances and harder impacts. Even a modest increase in speed can turn a minor fender-bender into a collision with major vehicle damage and a greater chance of injury.
Why is distracted driving a factor in freeway pileups?
A driver glancing at a phone or dashboard for even a couple of seconds can miss brake lights ahead. On a freeway, that delay often removes any chance of stopping in time once traffic bunches up.
Do weather or road conditions play a role in crashes like this?
Wet pavement, glare, or debris can reduce traction and visibility, making it harder for drivers to react to sudden slowdowns. Even on a clear day, congestion alone can create the same kind of split-second decision-making that leads to a chain-reaction crash.
What to Do After a Multi-Vehicle Car Accident in South Los Angeles, CA
If you're involved in a multi-car crash on a freeway, try to move to the shoulder if your vehicle is drivable and it's safe to do so, then turn on hazard lights to warn oncoming traffic. Call 911 and give your location as precisely as possible since freeway mile markers help first responders find you faster.
Even if you feel fine, consider getting checked by a medical professional. Adrenaline can mask pain from whiplash or other injuries that show up hours or days later. Exchange information with other drivers if it's safe, and take photos of vehicle positions and damage before cars are towed.
Keep a copy of the CHP incident report once it's available, and follow up with your insurance company promptly. If you were a passenger or bystander, note what you saw, small details can matter later when piecing together how the crash unfolded.
