RIVERSIDE, Riverside County, Calif., Sept. 22, 2026 — A hit and run crash left at least one person hurt on Monday afternoon, September 21, on westbound State Route 91 at the La Sierra Avenue offramp in Riverside, according to the California Highway Patrol.
The crash was initially logged as a traffic collision with unknown injuries before the California Highway Patrol reclassified it as a hit-and-run with injuries, officials said. A red Mazda hatchback and at least one other vehicle were reportedly involved, possibly in the number two lane, according to radio traffic tied to the incident.
One vehicle occupant was reportedly pushed into another car and may have needed medical attention, according to early reports from the scene. A red Toyota was left blocking the middle lanes of the westbound freeway following the crash, and Riverside Fire Department units responded to assist.
Freeway Service Patrol personnel were on scene and helped update the CHP's classification of the incident. Southbound La Sierra Avenue traffic was reportedly being rerouted through the westbound Magnolia Avenue offramp while crews worked the scene. The circumstances of the hit-and-run, including whether the fleeing driver has been identified, remain under investigation.
We hope those who were hurt recover fully and quickly.
Hit and Run Crashes: What the Numbers Show
According to the AAA Foundation for Traffic Safety, hit and run crashes accounted for 7 percent of all traffic fatalities when deaths reached 2,972 in 2022. That figure reflects only the fatal cases. It does not count the much larger number of hit-and-run crashes, such as the one reported on SR-91, that cause injuries but not deaths, meaning the true scale of drivers fleeing the scene is far bigger than fatality counts alone suggest.
Freeway hit-and-runs pose particular challenges for investigators. Vehicles are moving at highway speeds, lane changes happen quickly, and a fleeing driver can be gone before other motorists or responding officers can get a plate number or a clear description. Cases often hinge on witness statements, traffic cameras, or vehicle debris left at the scene.
California treats fleeing from an injury crash as a criminal offense separate from any fault in causing the collision itself. That distinction matters for investigators building a case, since it means charges can apply to the act of leaving regardless of how the crash occurred in the first place.
Frequently Asked Questions
How does speed affect how bad a crash is?
Higher speeds mean more energy is absorbed in a collision, so injuries tend to be more severe and vehicles sustain heavier damage. This holds true even on freeways where traffic is already moving fast, since a sudden lane change or impact leaves little time to slow down.
Why is distracted driving such a big factor in crashes like this?
A driver looking at a phone or otherwise not watching the road can miss a lane change, a slowing vehicle, or a merge, and by the time they react, it may be too late to avoid a crash. Distraction is a factor across nearly every category of collision, from freeway merges to stop-and-go traffic.
What should someone do right after a car accident?
Move to a safe location if possible, call 911, and check for injuries before doing anything else. Exchange information with other drivers if the scene allows it, take photos, and get medical care checked out, even if injuries seem minor at first.
What to Do After a Hit-and-Run Crash in Riverside, CA
If you're involved in or witness a hit-and-run, try to safely note details about the fleeing vehicle, such as color, make, or a partial plate, and report them to the California Highway Patrol as soon as possible. Even a partial description can help investigators.
Get checked by a medical provider even if you feel fine at the scene, since some injuries from being struck or jolted don't show symptoms right away. Keep records of any treatment, and file a report with police if one hasn't already been taken, since documentation matters for insurance and any later investigation.
If you're a passenger or bystander who saw what happened, consider reaching out to CHP investigators directly. Freeway hit-and-run cases often depend on tips from people who were nearby when it happened.
