COMMERCE, Los Angeles County, Calif., Oct. 19, 2026 — Multiple vehicles collided early on Monday morning, October 19, on the southbound I-5 connector to southbound I-710 in Commerce. At least one lane was blocked for an extended period as crews worked the scene.
The California Highway Patrol first logged a two-vehicle crash shortly before 6 a.m., reportedly involving a red Honda Civic and a white Dodge Ram blocking a lane on the connector. Within the hour, additional vehicles were reported involved, including a BMW X5 and a red Toyota pickup, and separately a red Toyota Tacoma and a dark-colored BMW. It remains unclear whether all reported vehicles were part of one chain-reaction crash or a series of related incidents in the same stretch of roadway.
Dispatch logs show the fast lane and the number one lane were blocked for a time as units responded. The report was upgraded from a collision with unknown injuries to one with an ambulance requested, though the extent of any injuries has not been released.
A Freeway Service Patrol unit worked the scene and closed out its response by about 6:44 a.m. The investigation into how the crash occurred, and how many vehicles and people were involved, is ongoing.
We wish the injured a complete and speedy recovery.

Frequently Asked Questions
How can drivers avoid getting caught in a pile-up on the freeway?
Keep scanning well ahead of the car directly in front of you, watch for brake lights rippling back through traffic, and be ready to slow early rather than react late.
What should I do if I come up on a crash blocking a lane on the highway?
Slow down well before reaching the scene, signal early, and merge out of the blocked lane as soon as it's safe. Avoid stopping in a travel lane unless directed to do so.
Why does following distance matter so much on connectors and ramps?
Connector roads commonly have tighter curves and sudden slowdowns. Extra space between vehicles gives drivers more time to react if traffic ahead stops unexpectedly.
What to Do After a Multi-Vehicle Crash in Commerce, CA
If you're involved in a multi-vehicle crash, try to move to a safe spot off the traveled lanes if your vehicle is drivable and it's safe to do so. Check yourself and any passengers for injuries, and call 911 even if injuries seem minor, since some symptoms take hours to appear. Exchange information with other drivers involved, and if CHP or another agency responds, ask how to obtain a copy of the official report once it's available. Getting checked by a medical provider soon after the crash can help document injuries and rule out issues that aren't immediately obvious.
