ORANGE, Orange County, Calif., Sept. 18, 2026 — A multi-vehicle crash blocked lanes on southbound State Route 57 at the interchange with State Route 22 on Thursday afternoon, September 17, according to authorities. The collision reportedly involved a green Mazda pickup truck and two to three other vehicles.
California Highway Patrol radio logs show the crash was first reported as a collision with unknown injuries before being reclassified to confirm at least one injury requiring medical response. The wreck blocked two slow lanes on the southbound interchange, backing up traffic in the area, authorities said.
Fire crews and paramedics responded to the scene, and one person was reportedly moved from a travel lane to the right shoulder as personnel worked the crash. A tow truck was requested for the green Mazda pickup involved in the collision.
The extent of injuries has not been released. The circumstances that led to the crash remain under investigation, and no further details on the vehicles or people involved have been made public.
We wish the injured a complete and speedy recovery.
Why Fatigue and Impairment Keep Causing Multi-Vehicle Crashes
Interchange crashes involving several vehicles often trace back to a driver who reacts a beat too late, and fatigue or impairment are two of the most common reasons for that delay. A tired driver's reaction time can slow in ways that mirror having alcohol in the system, even without a single drink, because the brain simply stops processing hazards fast enough.
Impairment from alcohol, drugs, or medication compounds the problem at merge points and interchanges, where drivers must judge gaps, adjust speed, and react to sudden braking from other cars within seconds. A driver whose judgment or coordination is affected is less likely to notice brake lights ahead in time to stop safely, which can start a chain-reaction collision involving several vehicles.
According to the National Highway Traffic Safety Administration, an estimated 1,947,298 passenger-vehicle occupants were injured in motor-vehicle traffic crashes in 2023. Interchanges like the one where SR-57 meets SR-22 concentrate the merging, braking, and lane-changing that can turn a single impaired or drowsy driver's mistake into a multi-car pileup.
Frequently Asked Questions
How does speed affect crash severity?
Higher speeds increase both the force of impact and the distance needed to stop, so crashes that happen at highway speed tend to cause more serious injuries than those in slower traffic.
Why is distracted driving so dangerous?
Taking eyes or attention off the road for even a few seconds removes the reaction time a driver needs to brake or steer away from a sudden hazard, which is often enough time to cause a collision.
How do weather and road conditions contribute to crashes?
Wet pavement, glare, and reduced visibility all extend stopping distances and make it harder for drivers to judge the speed and position of nearby vehicles.
What should I do immediately after a car accident?
Move to a safe location if possible, check for injuries, call 911, and exchange information with other drivers while documenting the scene if you're able to do so safely.
What to Do After a Car Accident in Orange, CA
If you're involved in a multi-vehicle crash near an interchange in Orange, try to move to the shoulder or a safe area if your vehicle is drivable, and turn on hazard lights to warn oncoming traffic. Call 911 to report injuries and request medical help, even if pain or symptoms seem minor at first, since some injuries don't appear right away.
Get checked by a medical provider as soon as you can, and keep records of any treatment. File a report with the California Highway Patrol or local police, and gather contact and insurance information from anyone else involved before leaving the scene, if it's safe to do so.
