Garden Grove, CA (September 11, 2026) – Four vehicles collided on Wednesday afternoon, September 9, on eastbound State Route 22 near Brookhurst Street in Garden Grove, according to authorities. At least one vehicle was left blocking traffic in the roadway.
The crash was first reported to the California Highway Patrol shortly before 1 p.m. as a collision involving a white van and a black Toyota RAV4, authorities said. A sport utility vehicle and a truck were also reportedly blocking the carpool lane in the aftermath, according to radio traffic.
Authorities said the wreck initially caused injuries that were unconfirmed in number or severity, and the incident was later logged as a crash with a party en route to the scene. Emergency crews closed the number one lane and the carpool lane while the collision was cleared, and a SigAlert was issued for about 30 minutes to manage the backup, according to CHP communications.
Tow crews, including a flatbed and a rotation tow truck, were called in to remove the vehicles from the roadway. Authorities said all four vehicles were off the roadway by early afternoon and the collision was ultimately classified as one with no reported injuries, though that classification remains subject to confirmation.
The California Highway Patrol has not released additional details on what led to the collision. The cause remains under investigation.
We hope those who were hurt recover fully and quickly.
What the Numbers Show About Multi-Vehicle Freeway Pile-Ups
According to the National Highway Traffic Safety Administration, 28,595 large-truck occupants were injured in multi-vehicle crashes involving large trucks in 2023. That figure reflects how often a single point of impact on a busy roadway can multiply into several damaged vehicles and several sets of injuries, especially when a heavier vehicle is part of the chain.
Multi-vehicle collisions on freeways often start small, a sudden stop, a lane change, a single fender-bender, before following traffic reacts too late. Each additional vehicle that gets pulled in adds new variables: different speeds, different following distances, different reaction times. On a corridor like SR-22, where lanes narrow near interchanges and traffic volumes stay heavy through the afternoon, that chain reaction can tie up several lanes at once.
Data from crashes involving four or more vehicles nationally shows that secondary impacts, cars striking ones already stopped from the first collision, account for a meaningful share of the injuries reported. That is part of why agencies push to clear wreckage and redirect traffic quickly once a multi-vehicle crash is reported.
Frequently Asked Questions
What typically causes multi-vehicle pile-ups?
They usually start with one vehicle slowing or stopping unexpectedly, often due to congestion, a minor collision, or a road hazard, followed by other drivers who can't stop in time to avoid the first vehicle or each other.
Why do these chain-reaction crashes escalate so quickly?
Once traffic is already dense, a small gap in following distance leaves little time to react. Each vehicle that gets struck can spin, stall, or shift lanes, creating a new hazard for the vehicles behind it.
How can drivers avoid getting caught in one?
Leaving extra space between vehicles, especially in heavy traffic, and watching brake lights several cars ahead gives more time to slow down safely if a crash starts to unfold.
What should I do if I'm stopped near a crash on the freeway?
Turn on hazard lights, stay in the vehicle if it's safe to do so, and move to the shoulder or a safe area away from moving traffic if possible. Call 911 to report the crash if it hasn't already been reported.
What to Do After a Multi-Vehicle Crash in Garden Grove, CA
If you're involved in a multi-vehicle crash, try to move to a safe location out of traffic and check for injuries before doing anything else. Call 911 even if the damage looks minor, since some injuries aren't obvious right away.
Exchange information with other drivers involved and take photos of the vehicles and the scene if you're able to safely do so. It's also a good idea to seek a medical evaluation soon after, even without obvious symptoms, since some injuries take time to appear. Keep a copy of the CHP incident report for your records once it becomes available.
