If you were hurt in a Muni accident in San Francisco, you generally must file a written government claim with the City and County of San Francisco within six months of the incident, not two years. Muni is operated by a public agency, so the ordinary personal injury timeline does not apply to your claim.
B&D Injury Law Group represents people injured in transit collisions in California. This article explains why the six-month deadline exists, what happens after you file, the heightened duty a transit agency owes its passengers, the defenses public agencies raise, and the steps that protect a claim in the first weeks.
What Makes a Muni Accident in San Francisco Different From a Regular Crash?
Muni is run by the San Francisco Municipal Transportation Agency, a department of the City and County of San Francisco. Because the defendant is a public entity, a Muni accident in San Francisco is governed by California’s government claims process, which requires a written claim before you can sue and sets a much shorter deadline.
This applies across the system: diesel and electric buses, Muni Metro light rail, historic streetcars, and cable cars. It also applies whether you were a passenger, a driver hit by a Muni vehicle, a cyclist, or a pedestrian struck at a stop.
The claim requirement is procedural, not optional. Filing a lawsuit without first presenting a claim usually results in dismissal, no matter how clear the liability is.
How Long Do You Have to File a Claim Against Muni?
Six months from the date of injury to present a written claim to the City and County of San Francisco, under Government Code section 911.2. If the city denies the claim, you generally have six months from the date the denial notice was mailed to file a lawsuit in Superior Court. Both deadlines are strict.
If the city never responds to your claim, a different and longer window applies, but relying on that is a bad plan. The safest assumption is six months to claim, then six months to sue.
There is a limited path to file a late claim application within one year if you missed the six-month window for a qualifying reason. It has to be applied for, it can be denied, and it is not something to count on.
| Step | Deadline | What it means |
|---|---|---|
| Present a written claim | 6 months from the date of injury | Required before any lawsuit against the city or SFMTA |
| City responds | Typically 45 days after the claim is received | The claim may be accepted, rejected, or left unanswered |
| File suit after a written rejection | 6 months from the date the rejection was mailed | Missing this ends the claim even if the injury is severe |
| Apply to file a late claim | Within 1 year of the injury | Available in limited circumstances, and it can be denied |
| Claim against a private third party | 2 years from the date of injury | Applies to a non-government driver or company that shares fault |
What Duty Does Muni Owe Its Passengers?
California holds common carriers, including public transit operators, to a heightened standard. A carrier that transports people for reward must use the utmost care and diligence for their safe carriage. That is a higher duty than the ordinary reasonable care standard that applies between two private drivers.
In practice this affects how a jury is instructed and how conduct is evaluated. Abrupt starts, closing doors on a passenger, pulling away before a rider is seated or clear, and failing to maintain equipment are all measured against that stricter standard.
The heightened duty applies to the transportation of passengers. If you were a pedestrian or another motorist hit by a Muni vehicle, ordinary negligence rules generally govern instead, though the practical evidence is much the same.
What Kinds of Muni Injury Claims Come Up Most?
The most common claims involve sudden stops and starts that throw standing passengers, boarding and exiting incidents, doors closing on riders, collisions with cars and pedestrians, and falls caused by wet or damaged flooring on a vehicle. Each has its own evidence trail.
Cyclists also bring claims tied to the light rail and streetcar tracks embedded in city streets. Those cases may be framed as a dangerous condition of public property rather than as a driver’s negligence, which brings in a different set of proof requirements and defenses.
Cable car incidents have their own pattern, involving grip and brake operation, standing riders on running boards, and boarding at busy turnarounds. These cases usually turn on operator conduct and maintenance records.
What Defenses Do Public Agencies Raise?
Expect three main arguments: that the claim was filed late or served on the wrong entity, that the injured person’s own conduct caused the fall, and that a roadway or facility design decision is immune from liability because it was formally approved. Each one is answered with different evidence.
Comparative fault comes up in nearly every passenger case. The agency will argue you were standing when you could have been seated, not holding a rail, distracted, intoxicated, or moving while the vehicle was in motion. California uses pure comparative negligence, so partial fault reduces recovery by your percentage rather than eliminating it.
Design immunity is a specific defense in dangerous condition cases. It can be overcome, but it requires evidence about approval, plans, and changed conditions, and it is not the kind of issue that gets resolved in a phone call with an adjuster.
What Should You Do After a Muni Accident?
Because the claim window is short and the evidence is controlled by the agency, the first two weeks matter more than in an ordinary crash. The steps below cover what usually protects a claim, and the last one is the most time-sensitive.
- Get medical care the same day and make sure the records reflect that the injury happened on or was caused by a transit vehicle.
- Report the incident to the operator or to Muni before you leave, and note the vehicle number, run number, route, direction, and time.
- Photograph the interior, the specific hazard, the exterior of the vehicle, the stop, and your injuries.
- Get names and phone numbers from other passengers immediately, since they scatter within minutes.
- Request in writing that onboard and station video be preserved, because retention periods are short.
- Keep every bill, discharge instruction, work note, and receipt in one place from the beginning.
- Calendar the six-month government claim deadline the week the injury happens.
- Talk to a lawyer well before that six-month mark so the claim is prepared and served correctly.
Can You Also Sue a Private Driver Involved in the Same Crash?
Yes. If a private vehicle contributed to the collision, that driver is a separate defendant with a separate two-year deadline and separate insurance. Many Muni cases involve both a public agency and a private motorist, and pursuing only one can leave real coverage unused.
That combination changes strategy. A private driver’s liability insurance responds differently than a public entity, and the two defendants will usually blame each other, which can help establish that someone was negligent.
It also means the deadlines run on two separate tracks in the same case. The six-month claim deadline against the city arrives long before the two-year deadline against the driver, and the earlier one controls the pace.
Frequently Asked Questions
What if I already missed the six-month deadline?
You may be able to apply for permission to file a late claim within one year of the injury, but it must be requested, supported by a valid reason, and it can be denied. Do not assume the case is over without having someone review the dates. If a private party also shares fault, that separate claim may still be within its own two-year window.
Do I have to file the claim myself, or can a lawyer do it?
A lawyer can prepare and present the claim for you, and it is generally better to have it reviewed before filing. Government claim forms require specific information, and an incomplete or misdirected claim can create arguments later about whether it was properly presented. The filing itself is straightforward, but the details are where these claims get challenged.
Does Muni have to give me the onboard video?
Not automatically, and not on request from a passenger. Video is typically obtained through a preservation demand followed by formal discovery once a case is filed. The critical point is timing: transit video is often retained for a short period and then overwritten. A written preservation request sent early is the most reliable way to keep it available.
I fell because the operator braked hard. Is that enough?
It can be. California holds common carriers to a heightened standard of care toward passengers, and an unusually violent stop or start can support a claim. The agency will argue the stop was necessary to avoid a collision or that you should have been holding on. Video, other passenger accounts, and the vehicle’s operating data usually decide it.
What if I was hit by a Muni bus while walking or riding a bike?
The same six-month government claim deadline applies. The evidence differs, focusing on crosswalk position, signal timing, the operator’s turning path and blind spots, and nearby camera footage from businesses along the route. That outside footage is frequently overwritten within days, so canvassing for it quickly is one of the most valuable early steps.
