Can You Sue the Government Over a Dangerous Road or Sidewalk in California?

Last updated November 4, 2026

Mealey’s reported that a California jury found Caltrans bore most of the liability after a cyclist suffered serious head injuries when his bike struck a raised section of sidewalk. Many people ask the same thing after a fall or a crash on a cracked road or a lifted sidewalk: can you actually hold the government accountable? This article explains how California handles those claims.

Can you sue the government over a dangerous road or sidewalk in California?

Short answer: Yes, often. California lets you bring a claim against a city, a county, or Caltrans when a dangerous condition of public property causes an injury. You must show the condition was truly dangerous and that the agency knew, or should have known, and had time to fix it. A written claim is generally due within six months.

What did the Caltrans verdict report say?

The report describes a jury finding, and the verdict figure below is stated only as Mealey’s published it. Here is what it says.

• The report is dated October 26, 2026, with a Los Angeles dateline (Mealey’s).
• A California jury found that a bicyclist with serious head injuries, hurt when his bike struck a raised section of sidewalk, incurred damages of $11.5 million, according to Mealey’s.
• The jury found that the state Department of Transportation, known as Caltrans, bore 95% of the liability, according to Mealey’s.

We are not involved in that case, and this article does not take a side on its merits. A verdict can also be challenged after trial, so the story may not be over. We use it here because it raises a question many Californians have about everyday hazards.

What counts as a “dangerous condition” of public property?

A dangerous condition is a defect in public property that creates a substantial risk of injury when the property is used with reasonable care in a reasonably foreseeable way. Minor, trivial, or insignificant risks do not count. A stopped car with no lights on a freeway raises shared fault questions as well, as covered in our stalled car guide.

Dangerous condition in plain English: Government Code section 830 defines it as a condition of public property that creates a substantial risk of injury, not just a minor one, when the property is used with due care in a way that people would reasonably be expected to use it. Roads, sidewalks, bike lanes, curbs, and crosswalks can all qualify.

Under Government Code section 835, a public entity can be responsible for an injury if you can show all of the following:

• The property was in a dangerous condition when you were hurt.
• The condition caused your injury.
• The condition created a reasonably foreseeable risk of the kind of injury you suffered.
• Either an employee of the agency created the condition, or the agency had notice of it in time to take steps to protect against it.

That last point is often where cases are won or lost.

What does “notice” mean, and how do you prove it?

Notice means the agency knew about the problem, or should have known, early enough to fix it or warn people. California recognizes two kinds, both described in Government Code section 835.2.

• Actual notice: The agency actually knew the condition existed and knew, or should have known, that it was dangerous. A prior complaint, a 311 report, an earlier claim, an inspection note, or a maintenance work order can show this.
• Constructive notice: The condition existed for long enough, and was obvious enough, that a careful agency would have found it. The law lets the agency point to its inspection system as evidence, so inspection schedules and records often matter.

An agency can also argue that what it did about a hazard was reasonable, considering the cost and practicality of a fix compared with the risk (Government Code section 835.4). That is one more reason records matter.

Is a small crack or lip too minor to sue over?

Sometimes, but size alone does not decide it. California’s trivial defect rule lets a court dismiss a claim only when no reasonable person could find the defect created a substantial risk of injury.

Trivial defect rule in plain English: Under Government Code section 830.2, a condition is not a dangerous condition if a court, looking at the evidence in the way most favorable to the injured person, decides as a matter of law that the risk was minor, trivial, or insignificant given the surrounding circumstances. Courts often look at more than a tape measure. In one published decision, the Court of Appeal said a court should consider all the circumstances that might make a defect more dangerous than its size suggests (Nunez v. City of Redondo Beach). Those can include jagged or broken edges, poor lighting, debris or water hiding the defect, whether it was dark, and whether anything blocked the view.

So a lip that looks small in daylight can look very different to a rider on a bike at dawn. That is why photos that capture lighting and surroundings are so important.

What is design immunity, and can it block a claim?

Design immunity can protect an agency when an injury is caused by the design of a road or improvement that was properly approved, and the approval was reasonable. It is a defense the agency must prove.

Design immunity in plain English: Under Government Code section 830.6, a public entity is generally not liable for an injury caused by the plan or design of a public improvement if the plan was approved in advance by the proper body or official, or the work followed approved plans, and a court finds there was substantial evidence from which a reasonable public employee could have approved that design. This can come up with curb heights, bike lane layouts, and sidewalk transitions that were built as designed.

It is not always the end of the story. California courts have recognized that immunity can be lost when conditions change over time, so that the design is no longer reasonably safe, and the agency had notice of the problem and a reasonable chance to fix it. For an example of how this plays out on state roads, see our post on crashes near a Caltrans lane closure or eroding road.

Does it matter if the cyclist or pedestrian was partly at fault?

Yes, it can reduce what you recover, but it does not automatically end a claim. California uses comparative fault, which lets a court or jury assign a percentage of responsibility to each person.

Comparative fault in plain English: If a jury decides you were partly to blame, your compensation is reduced by your share. The jury in the verdict Mealey’s describes found Caltrans 95% responsible, according to that report. Agencies commonly argue that the injured person was going too fast, was not watching the path, was using poor lighting, or could have seen and avoided the defect. Cyclists should also know that rules about riding on sidewalks vary by city. Pedestrians face similar arguments about distraction and attention.

If you were hurt on a bike or an e-bike, see our pages on e-bike accidents, what to do after a bicycle accident, and solo e-bike crashes involving curb and road design. For walking injuries, see pedestrian and micromobility accidents.

Who owns the road or sidewalk, and why does it matter?

It matters because the owner is the party you must hold responsible, and claims must go to the right agency on time. A mistake about who owns the property can cost you precious weeks.

• City streets and sidewalks: The city generally controls them, but some city codes put sidewalk repair duties on the adjacent property owner, so more than one party can be involved.
• County roads: In unincorporated areas, the county usually controls them.
• State highways: Caltrans controls state routes, including many streets that carry a local name, and the sidewalks and bike paths beside them.
• Other agencies: Schools, transit agencies, parks districts, and special districts have their own property. Federal land follows different rules.

Finding the owner can take real work. Maps, parcel records, and public records requests help, and a lawyer can often sort it out quickly. For how a claim against a state agency works, see our government claims page.

What is the deadline to bring a claim against a city, county, or Caltrans?

A written claim must generally be presented within six months of the injury. Our guide to pothole crash claims covers what to photograph. That is much shorter than the two-year deadline for most injury cases.

Government Claims Act in plain English: California requires most people with injury claims against a public entity to present a formal written claim first. Only after the claim is rejected, or is treated as rejected, can a lawsuit be filed. The steps are:

1. Six months to present the claim. For injury to a person or to personal property, the claim must generally be presented within six months (Government Code section 911.2).
2. Forty-five days for the agency to respond. If it does not act within 45 days, the claim is generally treated as rejected (Government Code section 912.4).
3. Six months to sue after a written rejection. If the agency sends written notice of rejection, a lawsuit generally must be filed within six months (Government Code section 945.6).
4. Late-claim relief is narrow. If the six months have passed, you can ask the agency for permission to file late, generally within one year of the injury and only for limited reasons (Government Code section 911.4). If the agency says no, a court petition may be possible within a short window (Government Code section 946.6). Do not count on it.

Claims against the State of California, including Caltrans, are generally presented to the state’s Government Claims Program rather than to a city clerk. Starting in 2027, California also requires the person signing a government claim to declare it is true to the best of their knowledge. See our post on the AB 2529 declaration rule. The same claim process applies to other city claims, such as our recent explainer on when a police car hits a pedestrian.

What should you document after a fall or crash on a dangerous road or sidewalk?

Document the hazard before it changes. Agencies often repair a defect after an injury, and the proof of what it looked like can disappear.

• Photos with a measuring reference. Place a tape measure, ruler, or familiar object beside the defect. Take close shots, wide shots, and a shot from the direction you were traveling.
• Lighting and conditions. Note the time of day, weather, whether streetlights were working, and anything that blocked the view.
• Exact location. Record the address, cross streets, nearest pole or landmark, and a map pin. Street view history can also help.
• Prior complaints. Look for 311 reports, online service requests, earlier claims, news stories, and neighborhood posts about the same spot.
• Witnesses. Get names and phone numbers, and ask whether they have video.
• Medical records. Keep every record, bill, and instruction, starting with the first visit.
• Damaged gear. Keep your bike, helmet, glasses, phone, shoes, and clothing as they are. Do not repair or wash them.
• Ride or phone data. Fitness app data, bike computer data, and phone photos with time stamps can help show where and when it happened.

What should you do next?

Get medical care first, then protect the evidence and the calendar. The six-month claim period is short, and it begins on the date you were hurt.

1. Get medical care. Tell the provider exactly how you were hurt, including your head, neck, and back symptoms.
2. Photograph the hazard right away. Use the checklist above, and return later in different light if you safely can.
3. Write down the date and the location. The claim deadline is counted from the injury.
4. Identify the owner. Check whether the road or sidewalk belongs to a city, a county, or Caltrans.
5. Do not give recorded statements to an adjuster without advice. Do not sign releases either.
6. Ask that records be kept. A lawyer can send a written preservation request and file public records requests for inspection logs, complaints, and repair records.
7. Speak with a lawyer early. The agency, the facts, and the deadline all affect your options.

Frequently asked questions

Can you sue the government over a dangerous road or sidewalk in California?

Often, yes. A city, county, or Caltrans can be responsible for a dangerous condition of public property if the agency created it or knew, or should have known, about it and had time to fix it. A written claim must generally come first.

How long do you have to file a claim for an injury on a public sidewalk or road?

A written claim for injury must generally be presented within six months. The agency then has 45 days to respond, and a lawsuit generally must follow within six months of a written rejection. Late-claim relief is limited.

What is the trivial defect rule?

Under Government Code section 830.2, a court can find that a defect was too minor to be a dangerous condition as a matter of law. Courts look at more than size, including lighting, edges, debris, and visibility.

What is design immunity?

Under Government Code section 830.6, an agency may be protected when an injury is caused by an approved design that had a reasonable basis. The immunity can be lost if conditions changed and the agency had notice and a chance to fix the problem.

Can a cyclist or pedestrian still recover if they were partly at fault?

Often, yes. California’s comparative fault rules reduce compensation by the injured person’s share of fault rather than barring the claim outright.

How do you find out whether a city, a county, or Caltrans owns the road?

Check maps and parcel records, and ask the agencies in writing. A lawyer can also use public records requests. Getting the owner right matters because the claim must go to the correct agency within the deadline.
