Trial Attorneys vs. Billboard Attorneys: The Bay Area Advantage
San Francisco highways and Muni stations are covered with advertisements for “billboard attorneys.” What these billboard operations rarely tell you is that they primarily run high-volume settlement mills. They take on hundreds of files, avoid taking depositions, and push clients to accept quick, discounted insurance payouts because they do not have the trial resources or courtroom appetite to face defense teams before a jury.
At Karns & Karns, we are Trial Attorneys. Insurance carriers and corporate defendants know exactly which law firms step into the courtroom and which ones take the first settlement offer. When corporate carriers and municipal defense lawyers see Karns & Karns representing you, they understand that our team is fully prepared to take the verdict to trial. That courtroom reputation is the leverage needed to command maximum financial value for your claim.
Decades of Proven Results & $300M+ Recovered
Our firm has successfully secured more than $300 million in settlements and verdicts for injured individuals. We possess the substantial trial capital, technology, and forensic resources required to take on national trucking fleets, gig-economy tech companies, and commercial premises owners.
Our Dedicated California Commercial & Trial Litigation Team
Our California clients are backed by a dedicated commercial accident and trial litigation team specifically focused on high-stakes motor vehicle crashes, commercial fleet liability, and complex catastrophic injury claims across Northern and Southern California. Our trial attorneys bring extensive courtroom experience, deep familiarity with California Civil Procedure, and an aggressive stance against corporate insurance tactics, ensuring every case is positioned for maximum financial recovery.
Car & Highway Collisions: We represent drivers, passengers, and families injured in severe collisions along US-101, I-80, I-280, 19th Avenue, and congested city arterials. Whether dealing with distracted motorists, speeding, or drunk driving, our trial attorneys work quickly to secure critical evidence and maximize your financial compensation.
18-Wheeler & Commercial Truck Accidents: San Francisco is surrounded by major commercial distribution channels feeding the Port of Oakland, Silicon Valley, and San Francisco logistics hubs. Collisions involving semi-trucks, box trucks, flatbeds, and delivery fleets involve complex federal FMCSA regulations. Our dedicated commercial litigation team immediately demands preservation of electronic logs, dashcam footage, and engine control module (ECM) black box data to prove corporate liability.
Pedestrian & Crosswalk Accidents: With heavy foot traffic, rideshare drop-offs, and complex intersections, pedestrian accidents in San Francisco frequently cause catastrophic fractures, internal trauma, and head injuries. We aggressively protect pedestrian rights, establishing liability even when insurance companies attempt to shift blame to the pedestrian.
Bus & Public Transit Accidents: Collisions involving San Francisco Municipal Transportation Agency (Muni) buses, light rail, historic streetcars, or regional transit providers require special handling. Claims against public transit entities carry strict administrative notice requirements under the California Government Claims Act (often within 6 months). Our firm handles these filings swiftly to preserve your right to compensation.
Uber & Lyft Rideshare Accidents: As the birthplace and headquarters hub of major rideshare companies, San Francisco sees a tremendous volume of Uber and Lyft vehicles. Liability involves navigating layered personal policies and the active $1 Million commercial liability policies depending on the driver’s app status. We hold rideshare insurers fully accountable for passengers, other drivers, and injured pedestrians.
Construction Site Injuries: With continuous commercial, infrastructure, and high-rise construction across San Francisco, workers face extreme hazards. We represent injured tradespeople and construction workers by pursuing third-party personal injury claims against negligent general contractors, property owners, and equipment manufacturers to recover compensation well beyond standard workers’ compensation.
Slip & Fall / Premises Liability: Commercial retailers, parking garages, and residential building managers in San Francisco have a legal obligation to maintain reasonably safe conditions. If dangerous flooring, broken stairs, poor lighting, or code violations caused you to suffer serious injuries, we hold negligent property managers responsible.
Motorcycle Accidents: Motorcyclists splitting lanes or commuting across Bay Area bridges face serious risk from distracted passenger vehicles. We combat anti-motorcycle insurance bias to secure full compensation for medical procedures, rehabilitation, and lost earnings.
Wrongful Death Claims: If corporate negligence or a reckless driver caused the tragic loss of your family member, our compassionate trial attorneys will handle the entire legal burden, taking the fight to corporate defendants so your family can focus on healing.







Call 911 immediately so the San Francisco Police Department (SFPD) or California Highway Patrol (CHP) can arrive and document an official traffic collision report. Seek a thorough medical evaluation right away, even if adrenaline masks your symptoms. Document the scene with photographs, gather witness details, and never provide a recorded statement or accept a quick settlement from an insurance adjuster before consulting our trial team.
Billboard lawyers frequently operate high-volume settlement mills where cases are settled cheaply to maintain fast turnover. Insurance companies evaluate your claim based on whether your lawyer actually takes cases to court. As Trial Attorneys, we prepare every case for a jury trial from the first day, which forces insurance carriers to put their highest offers on the table.
Under the California Government Claims Act, you generally have only 6 months (180 days) from the date of the injury to file a formal administrative claim against a government entity like SFMTA/Muni or the City and County of San Francisco. Failing to meet this strict deadline can permanently bar you from recovery, making immediate legal representation essential.
Yes. While workers' compensation covers a portion of lost wages and medical care regardless of fault, it does not compensate you for pain, suffering, or full future loss of earning capacity. We investigate job site accidents to identify negligent third parties such as general contractors, scaffolding suppliers, or property owners allowing us to file a comprehensive civil lawsuit for maximum recovery.
At Karns & Karns, we handle all personal injury and accident claims on a pure contingency fee basis. You pay $0 upfront, and we advance all investigative, filing, expert witness, and trial costs. If we do not successfully recover money for your claim through a settlement or jury verdict, you owe us nothing.
