On September 24, 2026, the California Court of Appeal, Second District, sided with the City of Rancho Palos Verdes in Tansavatdi v. City of Rancho Palos Verdes. This was a wrongful-death case brought by the family of a bicyclist killed on a city road. The court ruled that “design immunity” — a legal shield for public entities — can still protect the city even when a grieving family argues the warning signs on that road weren’t good enough. Here’s why this matters: if you’ve been hurt, or lost a loved one, in a crash on a city or county road anywhere from West Covina to Los Angeles, Anaheim, San Bernardino, Riverside, Ontario, or Pomona, this case affects you. Government injury claims move fast. The deadlines are shorter and the legal hurdles are higher than in a typical case. Don’t wait to talk to someone about it.
Background: What This Means
Design immunity comes from California Government Code Section 830.6. Think of it as a legal shield. It protects cities, counties, and the state from getting sued over road designs that a government body signed off on before construction. To use this shield, the government generally has to prove three things: a government employee approved the plan, that approval happened before the road was built, and there was a reasonable basis for approving that design at the time. Sounds simple. It rarely is.
The court’s full opinion is available through the California Courts website at courts.ca.gov. This ruling affirmed summary judgment for the city, meaning the case ended before it ever reached a jury.
How This Affects Cyclists, Pedestrians, and Drivers in Southern California
This ruling raises the bar for people injured on public roads in Los Angeles County, Orange County, San Bernardino County, and Riverside County. Many dangerous intersections, sharp curves, and unmarked hazards exist on city and county roads throughout West Covina, Anaheim, Pomona, Ontario, and nearby areas. When a bicyclist, pedestrian, or driver is hurt at one of these locations, the public entity will often raise design immunity as a defense, even if the accident victim believes better signage or warnings could have prevented the harm.
Under this decision, simply arguing that a warning sign was insufficient may not be enough to defeat design immunity on its own. Injury victims and their families will likely need to show something more, such as a change in traffic conditions after the original design was approved, or evidence that no reasonable public official could have approved the design in the first place. This makes early evidence gathering and a careful legal review even more important in cases against government entities.
What You Should Do Now
- Act quickly. Claims against California government entities generally must be filed within six months of the injury under the Government Claims Act. Missing this deadline can end a case before it starts.
- Document the scene. Take photos of the road, any signs, lane markings, and the surrounding area as soon as possible, since conditions can change or be repaired.
- Gather records. Collect police reports, medical records, and witness contact information related to the crash.
- Request public records. Design plans, approval dates, and maintenance logs held by the city or county may be requested through a California Public Records Act request.
- Speak with an attorney before accepting any settlement. Government entities may offer quick settlements that do not reflect the full value of a claim, especially in cases involving a serious injury or wrongful death.

Frequently Asked Questions
What is design immunity in California?
Design immunity is a legal defense under Government Code Section 830.6 that can protect public entities, like cities and counties, from lawsuits over injuries caused by an approved road design. The entity generally must show that a government employee approved the plan and that the approval was reasonable at the time it was made.
Does this ruling mean I cannot sue a city after a cyclist or pedestrian accident?
No. It does not close the door on every claim. It means that arguing the warning signs were simply inadequate, when a warning already existed as part of the approved design, may not be enough on its own. Other legal theories, such as changed conditions or lack of reasonable approval, may still support a claim.
How much time do I have to file a claim against a California city or county?
Under the California Government Claims Act, claims against public entities generally must be filed within six months of the injury. This is much shorter than the two-year deadline that usually applies to private party injury claims, so prompt action matters.
What evidence can help overcome a design immunity defense?
Evidence that traffic patterns, speed, or hazards changed significantly after the original design was approved can sometimes help. Evidence showing that no reasonable official could have approved the design given the information available at the time may also be relevant. Each case depends on its own facts.
Can I still recover damages if the city has design immunity?
It depends on the facts of the case. Other parties, such as a negligent driver, a contractor, or a property owner, may still be responsible even when a public entity is protected by design immunity. An attorney can review the full circumstances of the crash to identify who may be liable.
