San Francisco Truck Accident Lawyer

Injured in a Truck Accident in San Francisco? Sonya Tien Fights for Maximum Compensation.

Big rigs, delivery vans, garbage trucks, and freight haulers move through San Francisco’s densest neighborhoods every single day — squeezing through narrow streets, tight turns, and some of the city’s most dangerous intersections. When a fully loaded commercial truck collides with a car, motorcycle, cyclist, or pedestrian, the results are rarely minor. Victims are often left with catastrophic, life-altering injuries and a tangle of corporate insurance adjusters working to minimize what they pay.

Tien Law Firm is a California personal injury law firm with an office in San Francisco, founded by Sonya Tien, an award-winning San Francisco personal injury lawyer with more than a decade of experience taking on trucking companies and their insurers. Sonya has built her career fighting for injured people across the Bay Area, and she knows exactly how San Francisco truck accidents happen — from the Hairball to the Port, from Bayshore Boulevard to the Bay Bridge approach.

Why Truck Accidents Are So Common — and So Dangerous — in San Francisco

San Francisco wasn’t built for big trucks, but they’re everywhere: hauling freight to and from the Port of San Francisco, servicing the produce and industrial businesses in the Bayview, and navigating delivery routes through some of the city’s most congested corridors. Our firm regularly handles truck accident cases from the city’s most dangerous streets and intersections, including:

The “Hairball” — where Bayshore Boulevard, Cesar Chavez Street, Potrero Avenue, and Marin Street collide near the produce market and Highway 101 on- and off-ramps. This tangled interchange is part of the city’s official High-Injury Network and sees heavy commercial truck traffic serving nearby industrial businesses.
Bayshore Boulevard at Jerrold Avenue, a high-volume corridor through the Bayview’s industrial district where large trucks regularly merge with commuter traffic entering and exiting Highway 101.
Potrero Avenue at 16th Street, a notoriously congested intersection where delivery trucks and turning vehicles create dangerous merging conflicts.
The Alemany Interchange, connecting I-280, Highway 101, and Alemany Boulevard near the Alemany Farmers Market — a complex, high-speed merge point for freight and commuter traffic alike.
Third Street and Cesar Chavez Street, key routes for trucks accessing the Central Waterfront and Dogpatch industrial areas.
Van Ness Avenue and the U.S. 101 corridor, a major truck route running the length of the city.
The I-80 approach to the Bay Bridge, where merging freight traffic and heavy congestion routinely cause rear-end and multi-vehicle truck collisions.

Common Causes of San Francisco Truck Accidents

Our firm has represented clients injured in truck accidents caused by:

Driver fatigue, particularly among long-haul and delivery drivers under pressure to meet tight schedules
Distracted driving, including cell phone use behind the wheel
Unsafe turns and blind spots on narrow San Francisco streets not designed for large commercial vehicles
Improper lane changes and merging near freeway on-ramps like the Hairball and the Alemany Interchange
Speeding or failure to yield at congested intersections such as Potrero and 16th
Overloaded or improperly secured cargo causing rollovers or spilled loads
Poor truck maintenance, including brake failure and tire blowouts
Trucking company negligence, including violations of federal hours-of-service regulations

Injuries We See in San Francisco Truck Accident Cases

Because of their sheer size and weight, commercial trucks cause injuries far more severe than typical car accidents. Clients come to us after truck collisions resulting in:

Traumatic brain injuries and concussions
Spinal cord injuries and paralysis
Crush injuries and traumatic amputations
Multiple fractures requiring surgery
Internal organ damage and internal bleeding
Severe road rash and lacerations
Wrongful death

Many victims of serious truck accidents in San Francisco are taken to Zuckerberg San Francisco General Hospital and Trauma Center at 1001 Potrero Avenue in the Mission District — the city’s only Level I Trauma Center, serving all of San Francisco and northern San Mateo County. Others receive emergency care at CPMC Van Ness Campus or UCSF Medical Center at Parnassus. If you or a family member was treated at any of these facilities after a truck accident, Tien Law Firm can help you pursue full compensation for your medical bills and ongoing care.

What to Do After a Truck Accident in San Francisco

Call 911 and get medical attention immediately — truck accident injuries are often more severe than they first appear.
Document the scene — photograph the truck, its company markings and license plate, the street or intersection, and any visible damage or injuries.
Get the police report number and contact information for any witnesses.
Do not speak with the trucking company’s insurance adjuster before consulting an attorney — trucking companies often send investigators to the scene within hours.
Call Tien Law Firm at (415) 881-8820 before accepting any settlement offer.

Truck accident claims are more complex than typical car accident cases. They often involve multiple liable parties — the driver, the trucking company, a cargo loading company, or even a vehicle manufacturer — and federal trucking regulations that most attorneys aren’t equipped to navigate. California also allows for comparative negligence, meaning insurers will often try to shift blame onto injured victims to reduce what they owe.
