NATIONAL CITY, San Diego County, Calif., Oct. 1, 2026 — At least one person was hurt on Tuesday afternoon, September 29, in a multi-vehicle crash on westbound State Route 54 near Woodman Street in National City, according to the California Highway Patrol.
The crash reportedly involved two to three vehicles and left all westbound lanes blocked, the California Highway Patrol said. Early radio traffic described a silver sedan colliding with an unknown vehicle before a black pickup and a silver Hyundai Elantra were also pulled into the wreck, along with a black SUV, though the exact sequence has not been confirmed.
At some point during the crash, a black vehicle rolled over and came to rest on its wheels, per the CHP log. Drivers and passengers reportedly got out of their vehicles and were seen standing in the roadway amid moving traffic, a dangerous situation that prompted additional calls for help managing the lanes.
CHP units responding to the scene upgraded the call from a collision with unknown injuries to one with an ambulance en route, confirming at least one injury. Officers blocked off roughly half the roadway to work the crash and requested a tow truck to begin clearing the vehicles.
No further details on injury severity, names, or ages have been released. The crash remains under investigation.
We wish those injured a full recovery.
Where Multi-Vehicle Pile-Ups Tend to Happen
Multi-vehicle crashes like this one tend to cluster at points where traffic patterns change fast, and drivers have little time to react. Freeway segments near interchanges, merge points, and lane shifts are common trouble spots because speeds vary widely from one lane to the next and visibility can be blocked by curves, grades, or other vehicles.
Wide urban highways carrying heavy commuter volume add another layer of risk. When one vehicle slows or stops without warning, following drivers usually have only a few car lengths to respond, and a single hard brake can set off a chain of collisions behind it. Afternoon and evening commute hours, when traffic density peaks, are when these pile-ups are most likely to start.
According to the Insurance Institute for Highway Safety, 24 percent of fatally injured occupants in crashes classified as other, which were mostly rollovers, were belted in 2023. That figure is a reminder that rollovers, which can occur even in multi-vehicle crashes that start as simple rear-end or sideswipe collisions, carry their own injury risks separate from the initial impact.
Frequently Asked Questions
What typically causes a multi-vehicle pile-up?
These crashes usually start with one vehicle slowing, stopping, or losing control, usually because of a hazard, heavy traffic, or a smaller collision. Vehicles behind it then have limited time and space to stop, and the result is a chain reaction involving several cars.
Why do chain-reaction crashes happen so quickly?
Following distances on busy highways are usually too short for the speeds involved. When one driver brakes hard, every driver behind has less reaction time than the one before, so small delays compound fast across a line of traffic.
How can drivers avoid getting caught in one?
Leaving extra space ahead, watching brake lights several cars up rather than just the car directly in front, and slowing early when traffic density increases all help. Avoiding distractions matters most in heavy traffic, where reaction time is already limited.
What should I do if I come upon a crash scene on the highway?
Slow down well before reaching the scene, turn on hazard lights, and merge away from blocked lanes as soon as it's safe. Never stop in a travel lane to look or help unless you can pull fully onto the shoulder.
What to Do After a Multi-Vehicle Crash in National City, CA
Anyone involved in a multi-vehicle crash should move to a safe location away from traffic as soon as possible and call 911 if that hasn't already happened. Even if injuries seem minor at first, a medical check is worth getting, since adrenaline can mask pain from impacts or a rollover until hours later.
Exchange information with other drivers if it's safe to do so, and take photos of vehicle positions and damage before vehicles are towed. Request a copy of the CHP report once it's available, and keep records of any medical visits related to the crash. If you were a passing driver who saw the crash happen, consider staying nearby long enough to speak with officers, since independent accounts usually help clarify how multi-vehicle collisions unfolded.
