CORONADO, San Diego County, Calif., Sept. 25, 2026 — A chain-reaction crash involving as many as 11 vehicles injured several people on Thursday morning, September 24, on westbound State Route 75 near the Coronado Bridge, according to the California Highway Patrol.
The pileup was reported around 6:05 a.m. near the toll plaza and midspan area at Pier 2. Dispatch logs show reports of six to seven vehicles involved early on, with the count growing to as many as 11 as more calls came in.
Vehicles described in the reports included a green Jeep Wrangler, a gray Subaru, a silver Honda, a black Mitsubishi and a white Ford pickup, among others left blocking or partially blocking the roadway. One driver reported a white Toyota Tacoma had collided with a black Ford Edge near the toll plaza, with the vehicle left in the dirt shoulder on the right side, hazard lights on.
The California Highway Patrol said the incident was initially classified as a collision with unknown injuries before being updated to reflect that a formal traffic break was in progress to manage the scene. The extent of injuries has not been released. It remains unclear what triggered the initial impact or how many people were hurt.
The crash remains under investigation, but officers have not released further details on the cause or on citations, if any.
We hope those who were hurt recover fully and quickly.
Why Highway Pileups Turn Small Impacts Into Big Ones
A crash involving several vehicles on a highway is rarely about one hard hit. It is about speed that does not go away fast enough. When a lead vehicle slows or stops, cars behind it are usually still traveling at highway speed, and the gap between "stopped" and "70 mph" can close in a couple of seconds. Each vehicle that strikes the one ahead adds its own momentum to the pile, so the last cars in the chain can hit with more combined force than the first collision alone.
Weight differences make this worse. A pickup or SUV striking a smaller sedan transfers energy unevenly, and the frame, bumper height, and crumple zones of each vehicle are not built to match every other vehicle on the road. Bumpers and crush zones are engineered to absorb an impact within a narrow range of speed and angle. Outside that range, the metal and safety systems do less to slow the deceleration passengers feel.
Airbags, seatbelts and crumple zones are designed for a single, defined hit, not repeated ones. A vehicle struck from behind and then pushed into the car ahead can absorb two impacts in quick succession, and safety systems built around one collision may already be spent by the time the second happens.
Frequently Asked Questions
Why do chain-reaction crashes happen?
They typically start with one vehicle slowing, stopping, or losing control, usually in fog, heavy traffic, or reduced visibility. Drivers behind may not have enough distance or time to react before striking the vehicle ahead, and each new impact can pull in more vehicles.
How can drivers avoid being caught in a pile-up?
Keeping a longer following distance, slowing early when brake lights appear ahead, and staying alert for sudden traffic changes are the main defenses. Reducing speed in fog, rain, or heavy congestion gives more time to react.
What should I do if I'm stopped near a crash on the highway?
Turn on hazard lights, stay in the vehicle if it's safe to do so, and move to the shoulder if possible. Watch for approaching traffic and be ready to exit away from moving lanes if you need to leave the vehicle.
How does fog or low visibility contribute to pile-ups?
Fog and low light shorten the distance at which drivers can see hazards ahead, which cuts the reaction time available before a collision. This is why multi-vehicle crashes usually cluster in early morning hours or areas prone to marine layer fog.
What to Do After a Multi-Vehicle Crash in Coronado, CA
If you're involved in or near a multi-vehicle crash, safety comes first. Move to a safe area away from traffic if possible, and call 911 to report injuries or hazards. Even if you feel fine, some injuries from a chain-reaction impact don't show symptoms right away, so a medical check afterward is a good idea.
Exchange information with other drivers involved and note anything you observed, such as weather or traffic conditions, while it's fresh. File a report with police or CHP if one hasn't already been taken at the scene. Coronado's bridge and highway approaches can back up quickly during peak commute hours, so if you regularly drive SR-75, giving extra following distance during foggy or high-traffic mornings is a simple habit that can make a difference.
