LONG BEACH, Los Angeles County, Calif., Oct. 11, 2026 — A six-vehicle crash blocked lanes on eastbound State Route 91 at Paramount Boulevard on Saturday afternoon, October 10, according to the California Highway Patrol.
The California Highway Patrol said a caller first reported five vehicles involved and blocking the carpool lane just west of Paramount. The count grew to six vehicles as officers arrived on scene. A gray Toyota Corolla, a black Chevrolet Impala and a white sedan were reportedly involved in the carpool lane, according to the CHP log, though the full sequence of impacts has not been detailed.
Fire crews responded and were blocking the carpool lane while working the scene, the agency's log shows. One lane was coned off as personnel worked to clear the roadway. Authorities have not released information on injuries beyond the initial classification of the incident as a crash with unknown injuries, which was later updated to confirm injuries had occurred.
The crash was also logged as a misdemeanor hit-and-run under California Vehicle Code 20002, according to CHP records, meaning at least one driver reportedly left the scene before exchanging information. Tow trucks were called to clear the vehicles, and traffic was reported fully released from the scene shortly after 2 p.m., with all vehicles moved off the roadway near Paramount Boulevard.
No further details on the drivers, passengers, or extent of injuries had been released as of Saturday afternoon. The investigation remains open.

When Multi-Vehicle Pileups Are Most Likely to Happen
Chain-reaction crashes involving several vehicles tend to cluster around the same time windows every day: the midday and afternoon commute windows, when traffic density is highest, and speeds vary widely between lanes. A carpool lane moving faster than adjacent lanes can turn a single hard brake into a pileup within seconds, especially when drivers are following closely to keep pace.
Weather is not the only trigger. Dense weekday traffic on a freeway like SR-91, where merging points and lane drops force frequent speed changes, creates repeated opportunities for rear-end chains even on clear afternoons. Fatigue and distraction build throughout a shift, and by early to mid-afternoon, reaction times among commuters already on the road for a while tend to slip.
According to the National Highway Traffic Safety Administration, 28,595 large-truck occupants were injured in multi-vehicle crashes involving large trucks in 2023. The numbers show how any vehicle mix, from passenger sedans to commercial trucks, can turn one driver's mistake into a crash involving several vehicles and multiple sets of injuries.
Frequently Asked Questions
How can drivers avoid getting pulled into a pileup?
Keeping a steady following distance and scanning several cars ahead, not just the one directly in front, gives drivers more time to react if traffic suddenly compresses or stops.
What should I do if I come up on a crash blocking the highway?
Slow down well before the blocked lanes, use hazard lights to warn traffic behind you, and avoid stopping in a travel lane if a shoulder or exit is reachable.
Why does low visibility make pileups worse?
Fog, glare, or heavy rain shortens the distance at which drivers can see trouble ahead, so a chain of vehicles already following closely has less room to stop before impact.
Why does following distance matter so much in freeway traffic?
A longer gap between vehicles gives each driver more time to brake smoothly rather than slam on the brakes, which often starts a multi-vehicle chain reaction.
What to Do After a Multi-Vehicle Crash in Long Beach, CA
If you're involved in a multi-vehicle crash, try to move to a safe location, such as a shoulder, if your vehicle is drivable and it's safe to do so. Check on yourself and any passengers for injuries before checking on others nearby.
Call 911 to report the crash and request medical help, even if injuries seem minor at first. Some injuries, especially to the neck, back, or head, don't show symptoms right away. Getting checked out by a medical professional creates a record that can matter later.
Exchange information with other drivers involved and note details such as vehicle positions and visible damage if you're able to do so safely. If you saw what happened to another vehicle in the crash, that observation can help investigators piece together the sequence of events.
