Available 
California Highway Patrol dispatch records show the incident was first reported at about 10:52 a.m. Vehicles were reported in or near the HOV and other westbound lanes, and debris was also reported in the roadway. Emergency responders were requested as the incident developed.
Later entries described three vehicles involved, while subsequent information referenced additional vehicles at the scene. By 11:01 a.m., the first three lanes were reported blocked. The incident was classified as a hit-and-run with injuries, but the available dispatch information does not establish the sequence of events or explain how the hit-and-run occurred.
The cause remains under investigation. We hope those injured in the crash make a full recovery.
Where the Collision Happened: Westbound SR-91 West of McKinley Street
The collision was reported on westbound State Route 91 west of McKinley Street. State routes carrying through traffic near local street access points can bring together vehicles traveling along the main corridor with traffic entering, exiting, or changing lanes near nearby connections.
The available dispatch record does not specify the exact point of impact, the posted speed, or the roadway movements that preceded the collision. Those details should not be assumed from the location alone.

Why Multiple Impacts Can Complicate a Car Collision
When several vehicles are involved in the same incident, the visible damage does not always immediately indicate which collision occurred first. An initial impact can redirect one vehicle into another lane or another vehicle, creating additional contact before traffic comes to a stop.
That issue is relevant to this State Route 91 crash because dispatch entries changed as responders gathered information about the vehicles at the scene. Establishing the sequence requires separating the initial collision from subsequent impacts, rather than treating every damaged vehicle as part of a single simultaneous contact.
How This Crash Is Investigated
Investigators handling a multi-vehicle hit-and-run may compare damage patterns and vehicle positions with statements from those involved to determine how the collision unfolded. Physical evidence can help establish which areas of the vehicles made contact and whether subsequent impacts occurred after the initial crash.
Because this incident was reported as a hit-and-run, identifying the vehicle or driver who left the scene may also be part of the investigation. The dispatch information provided does not identify that vehicle or state whether anyone was later located.
What to Do After a Car Crash in California
After a multi-vehicle crash, preserving medical records, photographs, towing paperwork, repair estimates, insurance correspondence, and other incident-related documents can help maintain a clear record of what happened. Obtaining the completed collision report can also provide information that may be more complete than early dispatch entries, especially when the number of vehicles or other scene details changes during the response.
For crashes investigated by the California Highway Patrol, reports may be requested through the CHP Crash Portal at crashes.chp.ca.gov or by using CHP 190 by mail or in person. The collision report itself is identified as CHP 555, while CHP 190 is the request form. California Highway Patrol lists an online portal fee of $22 and a mail or in-person fee of $10 per 25 pages.
A report becomes available after the officer files it, and the portal indicates when it is ready. Under Vehicle Code § 20012, eligible parties of interest include a driver, passenger, vehicle or property owner, parent or guardian, and a legal or insurance representative. These reports are not public and are restricted to parties of interest, with no fixed public-release window.
Local Accident Reports compiles incident information from official agencies and credible local sources. Details from initial reports may be updated as official investigations conclude. If you have direct knowledge that any information here is inaccurate, please contact us so we can review and correct the record.
