What If a Defective Road Sign or Traffic Signal Caused Your Accident in California?
January 6, 2026- Categories: Car Accidents
If a defective road sign or malfunctioning traffic signal caused your crash, you may have a claim. However, this process is legally distinct from a standard car accident claim against another driver. Cases like these fall under California Government Code § 835, which holds public entities liable for injuries caused by a “dangerous condition” on their property.
The challenge is that suing a government body, such as Caltrans, a city, or a county, requires overcoming a legal principle called Sovereign Immunity. This concept generally protects government entities from lawsuits. Fortunately, the law provides exceptions, but it puts a higher burden of proof on you, the injured party. You must show the government had notice of the danger and failed to act.
While the bar is higher, it is not insurmountable. Specific evidence, such as maintenance logs, public complaints, and previous accident reports at the same location, can be used to build a strong case.

Key Takeaways for Defective Road Sign Accident Claims
- You have only six months to file an administrative claim. This is a strict deadline under the California Government Claims Act, and missing it will prevent you from filing a lawsuit later.
- The government must have had “notice” of the dangerous condition. It is not enough that a sign was broken; you must prove the public entity knew or should have known about the hazard and failed to act.
- You may still recover damages even if you were partially at fault. California’s pure comparative negligence rule allows your compensation to be reduced by your percentage of fault, but it does not eliminate your right to a recovery.
Who Is Actually Responsible? (Identifying the Public Entity)
Determining who is responsible depends on where the accident occurred:
- Freeways and State Highways: The California Department of Transportation (Caltrans) is typically the responsible party.
- City Streets: The local municipality, such as the City of Los Angeles or the City of San Diego, is responsible for maintenance.
- County Roads: Roads in unincorporated areas usually fall under the county’s jurisdiction.
In some situations, liability might be shared between another driver and a government entity. We work to identify every responsible party to pursue the maximum compensation available under the law.
The “Dangerous Condition” Requirement: Proving Your Case
A broken traffic signal or a faded crosswalk does not automatically mean the government is liable. To win your case, you must prove that they knew, or should have known, about the hazard.
Under California Government Code § 835, we must establish four key elements to build a successful claim:
- Control: The public entity owned or controlled the property where the injury occurred.
- Dangerous Condition: The property was in a dangerous condition at the time of the accident, meaning it posed a substantial risk of injury even when used with reasonable care.
- Causation: The dangerous condition was a direct cause of your injuries.
- Notice: The entity either caused the dangerous condition or had adequate notice of it and failed to take corrective action.
That last point—Notice—is usually the most difficult to prove. It is established in two ways:
- Actual Notice: We find evidence that the entity knew about the specific hazard. For instance, public works logs show a repair ticket was opened for a malfunctioning light but was ignored for weeks.
- Constructive Notice: We work to prove the dangerous condition existed for such a long time that a reasonably diligent public entity would have discovered it. Think of a stop sign that has been knocked down for over a month; the city should have known about it through routine inspections.
Why Timelines Are Different for Government Claims
For most personal injury cases in California, you have two years to file a lawsuit. When suing a government entity, this rule does not apply at the outset.
The California Government Claims Act sets a much shorter, stricter deadline. You generally have only six months (180 days) from the date of your injury to file a formal administrative claim with the correct public entity. If you miss this deadline, you will likely lose your right to sue forever, no matter how severe your injuries are.
Here is how the process works in plain terms:
- You file a government claim first. This is a required document submitted to the correct city, county, state, or public agency.
- The agency reviews it. Most claims are denied. This is routine and does not reflect the strength of your case.
- Once the claim is rejected, you may file a lawsuit. A written rejection gives you six months to sue. If the agency never sends a rejection, you generally have two years from the injury date.
The strict timelines and procedural requirements make it extremely difficult for individuals to handle these claims on their own. Contacting an attorney promptly ensures these strict deadlines are met.
Evidence Vanishes Quickly: What We Look For
One of the first things a city or county will do after a serious accident is repair the hazardous condition. By the time you have recovered enough to return to the scene, the missing guardrail may have been replaced or the malfunctioning traffic signal may have been fixed.
This is why we act immediately to preserve evidence and reconstruct the scene. We know what to look for:
- Traffic Signal Logs: Modern “smart” traffic signals, like those being deployed in Los Angeles, record timing data. We request these logs to check for conflicts, such as two intersecting lights turning green simultaneously.
- Maintenance Records: Through formal legal requests, we subpoena maintenance and repair records. These documents may reveal if other citizens filed complaints about the same hazard weeks or months earlier, proving the city had “Actual Notice.”
- 311/Complaint Calls: We access public databases for records of calls or online reports from neighbors about an obscured sign or a massive pothole.
- Dashcam and Surveillance Footage: Video from nearby businesses, doorbell cameras, or vehicle dashcams is invaluable, but it is often deleted within days. We send preservation-of-evidence letters to ensure this footage is saved.
FAQ for Road Defect Accidents in California
Can I sue if foliage or a tree branch was blocking the stop sign?
Yes. Public entities are responsible for maintaining proper lines of sight for traffic controls. If overgrown vegetation owned by the city obscures a sign and causes an accident, it may be considered a dangerous condition.
What if the accident happened in a construction zone?
In these cases, liability could be shared between the government entity that owns the road and the private construction company hired to perform the work. Investigating these claims is difficult but entirely possible.
Who pays for the damage to my car if the city is liable?
The responsible entity pays for all damages, including property damage to your vehicle. However, securing payment from a government entity often takes much longer than settling a claim with a private insurance company.
We Hold the Government Accountable
Do not let the procedural hurdles of a government claim prevent you from pursuing the compensation you are owed. Public entities rely on the fact that the process is complicated, hoping that injured people will simply give up because they believe you can’t fight the government.
At Neale & Fhima, we handle the bureaucracy so you can focus on your recovery. If you believe a dangerous road, a defective traffic signal, or a missing sign caused your injuries, we need to begin our investigation before evidence is lost or overwritten.
