SAN FRANCISCO, San Francisco County, Calif., Oct. 25, 2026 — A driver was injured early on Saturday morning, October 24, when two vehicles collided inside the Yerba Buena Island Tunnel on eastbound I-80, according to the California Highway Patrol.
The crash was reported around 1 a.m. near the toll plaza transition inside the tunnel, where a black Tesla and a red hatchback, reportedly a Hyundai, came together. Officers initially logged the call as a collision with unknown injuries before upgrading it to a crash with a confirmed injury requiring an ambulance.
Responders found both vehicles occupied and the people inside out of their cars when crews arrived, per radio traffic relayed by the CHP's Traffic Management Center. The collision blocked the two right-hand lanes of the tunnel, backing up early-morning traffic through the span. One report also referenced a person possibly walking off the freeway near the Treasure Island off-ramp, though it's unclear if that was connected to the crash.
One of the people involved was reported to have an extent of injury requiring a medical evaluation, and officers requested a patrol unit to assist at the scene. A tow truck was also called to remove at least one of the vehicles. The CHP has not released further details on what led to the collision, and the incident remains under investigation.
We hope those who were hurt recover fully and quickly.

Frequently Asked Questions
What typically causes crashes like this one?
Collisions inside tunnels and on freeway approaches are usually linked to following too closely, sudden lane changes, or a driver's delayed reaction to slowing traffic ahead, though the specific cause here hasn't been released.
Does speed make a difference in how serious a crash is?
Yes. Even modest increases in speed reduce the time a driver has to react and increase the force of impact, which tends to raise the chance of injury.
Why is distracted driving considered so risky?
A driver looking at a phone or dashboard for even a few seconds can miss brake lights or a stopped vehicle ahead, especially in enclosed spaces like a tunnel where reaction time is already limited.
Can weather or road conditions play a role in tunnel crashes?
Tunnels remove rain and glare as factors, but sudden lighting changes entering or exiting a tunnel, along with reduced lane width, can still catch drivers off guard.
What to Do After a Car Accident in San Francisco, CA
If you're involved in a collision, move to a safe spot if your vehicle is drivable and turn on hazard lights, especially in a tunnel or on a bridge approach where traffic keeps moving fast. Check yourself and any passengers for injuries, and call 911 even if the damage looks minor, since adrenaline can mask pain from whiplash or internal injuries. Exchange information with the other driver and take photos of the vehicles and surroundings if it's safe to do so. Afterward, see a doctor for a full evaluation, even if you feel fine at the scene, and keep copies of any medical records, repair estimates, and the official collision report for your files.
