Pothole Accidents in San Diego: Who Is Liable?

Hitting a pothole sounds like a minor thing until it sends a motorcyclist into traffic, flips a bicycle, or jolts a car hard enough to cause a serious back or neck injury. The legal claim that follows is unlike a normal car accident case in almost every way. The defendant is often a government agency, the deadline to act is short, and the proof requirements are technical. This guide walks through how California law treats pothole accidents, who can be held responsible, how the government claim process works, and what to do in the first days after a crash. If a pothole injured you in San Diego, talking with a San Diego dangerous roadway conditions attorney early is the single best thing you can do to protect the case.

​

The Short Version

If you only have a minute, here is what matters most after a San Diego pothole accident:

• Who owns the road decides who you sue. City streets are usually the City of San Diego. Freeways and most state highways are Caltrans. Some roads belong to the County or to private owners.
• The government is only liable if it knew. Under California law, you have to show the agency either knew about the pothole or should have known long enough before your crash to fix it.
• You have six months to file a claim. Not two years. Government Code section 911.2 sets a strict six-month deadline to present a written claim before you can sue.
• The right form matters. The City of San Diego uses its own RM-9 claim form. Caltrans uses a separate state form.
• Property damage and injury claims are different animals. Most simple property damage claims are denied. Serious injury claims can recover substantial compensation when handled properly.
• Photographs and 311 records win cases. The city's own complaint records often prove that the pothole had been reported before your crash.

​

Property Damage Only, or Were You Injured?

Before going further, sort your situation into one of two buckets, because they are handled very differently.

If your only loss is property damage, a bent rim, a blown tire, or a cracked wheel with no injury to anyone, you usually do not need a lawyer. The fastest path is to file a damage claim directly with the agency that owns the road. For City of San Diego streets, file through the City's Risk Management liability claims page. For a state highway or freeway, file with Caltrans through its submit a damage claim page. Be aware that many property-only claims are denied on the notice rule explained below, but the filing is free and worth doing.

If you were injured, this is the guide for you. Injury claims carry far higher stakes, the proof requirements are more demanding, and the same six-month government deadline applies. Keep reading, and talk with a lawyer before you file anything.

​

Who Owns the Road and Why That Decides Who You Sue

The first question in every pothole case is jurisdictional, not factual. Before California law cares whether the pothole was dangerous, it cares who was responsible for maintaining that stretch of pavement. Get the wrong defendant and the case ends before it starts.

There are usually four candidates in San Diego.

• The City of San Diego. Most surface streets inside the city limits are city-maintained. Reports and repairs run through the City's Transportation Department, and claims for damage run through the Risk Management Department.
• Caltrans. The California Department of Transportation maintains state highways and freeways. In San Diego County that includes Interstate 5, Interstate 8, Interstate 15, Interstate 805, State Route 52, State Route 54, State Route 56, State Route 67, State Route 78, State Route 94, State Route 125, State Route 163, and State Route 905. If the pothole was on one of those, the claim runs through Caltrans, not the city.
• The County of San Diego. Unincorporated county roads, including stretches outside city limits in places like Ramona, Lakeside, and the back country, fall to the County's Department of Public Works.
• A private owner or contractor. Parking lots, private driveways, gated community streets, and active construction zones are usually controlled by a private property owner or a contractor. Those claims do not go through the government claim process and use ordinary premises liability rules instead. Our overview of premises liability laws in San Diego explains how those cases work.

One pothole, one stretch of road, can produce different defendants depending on a few feet of jurisdiction. The freeway is Caltrans. The on-ramp is usually Caltrans. The local feeder street twenty feet past the freeway exit is usually the city. A parking lot on the corner is private. The investigation begins with figuring out who owned the pavement at the exact point of impact.

​

What California Law Requires You to Prove

When the defendant is a public entity, the case is governed by the California Government Claims Act, not by ordinary negligence law. The key statute is Government Code section 835, which lists what a plaintiff has to prove to recover for a dangerous condition of public property.

There are four required elements:

1. The property was in a dangerous condition at the time of the injury.
2. The dangerous condition proximately caused the injury.
3. The dangerous condition created a reasonably foreseeable risk of the kind of injury that happened.
4. Either an employee of the public entity created the condition through a negligent act, or the public entity had actual or constructive notice of the condition long enough before the injury to have fixed it or warned of it.

Each piece of that test does real work.

The phrase "dangerous condition" has its own statutory meaning. Under Government Code section 830, a dangerous condition is one that creates a substantial risk of injury, as opposed to a minor, trivial, or insignificant risk, when the property is used with due care in a reasonably foreseeable way. The "substantial, not trivial" line is where many pothole cases live or die. California courts have repeatedly held that small surface defects, on the order of a few fractions of an inch in depth and a few inches across, can be trivial as a matter of law and defeat liability. A pothole large enough to swallow a tire, lift a bicycle off the pavement, or yank a motorcycle off its line is a different conversation.

The "used with due care" piece matters too. A pothole in the middle of the lane during normal driving is one case. The same pothole hit while a driver was speeding, weaving, or looking at a phone is another. California uses comparative fault, so a driver's own conduct will be weighed against the road's condition. Comparative fault rarely zeros out a serious injury claim, but it can reduce recovery.

​

The Notice Problem: The Reason Most Pothole Claims Fail

If there is one reason that ordinary pothole property damage claims are denied across San Diego every week, it is the notice requirement. California law does not make the city an insurer of every pavement defect. The city is liable only if it knew, or reasonably should have known, that the pothole existed long enough before your crash to do something about it.

That standard comes from Government Code section 835.2, which defines actual and constructive notice.

• Actual notice means the agency actually knew the pothole was there and knew it was dangerous. Prior complaints from residents, prior accident reports at that location, and internal work orders are all classic proof of actual notice.
• Constructive notice means the pothole had existed long enough, and was so obvious, that a reasonable inspection program would have caught it. The court looks at whether the agency had a reasonable inspection system, whether the system was actually used, and whether the condition would have shown up if it was.

This is where evidence wins or loses pothole cases. Useful evidence includes:

• Get It Done complaints reported by other residents about the same pothole or stretch of road, available through the City of San Diego's Get It Done system.
• Prior crash reports at or near the same location, obtainable from SDPD and CHP records.
• Maintenance logs, inspection records, and work orders, which can be obtained through California Public Records Act requests.
• The City's periodic pavement condition assessments. Roughly every five years, the City of San Diego hires an outside contractor to drive and photograph its entire street network and rate the condition of each segment, publishing the results as public Pavement Condition Assessment reports and maps (recent rounds were completed in 2011, 2016, and 2024). Because each survey photographs the actual pavement on a known date, an assessment image can show that a pothole already existed months or years before a crash, which is direct evidence the City was on notice of the dangerous condition.
• Photographs that show the size, depth, and age of the pothole, including indicators like edge erosion, embedded debris, and weathered patches.
• Witness testimony from neighbors, regular commuters, or local business owners who can confirm how long the pothole had been there.

The pattern is clear. A pothole that appeared the night before the crash, with no record of complaints, is a much harder case than a pothole that was reported through Get It Done weeks earlier and never repaired.

​

California's 6-Month Government Claim Deadline

The single most common way pothole injury claims get destroyed in San Diego is missing the six-month deadline. Government Code section 911.2 requires a written claim against a public entity for personal injury or property damage to be presented within six months of the date of the accident. That deadline is the trigger for everything else. Under Government Code section 945.4, you cannot sue a public entity until you have first presented a claim and the entity has acted on it or is deemed to have rejected it.

A few things to understand about that six-month clock.

It is much shorter than the standard personal injury statute of limitations. A normal injury claim in California has a two-year filing deadline under Code of Civil Procedure section 335.1. The government version is one-quarter that long. Our deep dive on the six-month claim deadline covers how this rule plays out in another government-defendant context, and the mechanics are very similar for pothole cases.

It is unforgiving. Late claim applications under Government Code section 911.4 are possible but hard to win, and judges generally require a strong reason for the delay, such as physical or mental incapacity. The safe move is to treat six months as the only deadline that matters.

It runs from the date of the injury, not the date you figured out who to sue. The clock is not paused while you investigate jurisdiction, gather records, or wait on medical treatment. The moment of the crash starts it.

If the wrong agency was named or if a piece of the claim is missing, the rejection notice can start an even shorter clock. After a claim is rejected, you generally have only six months from the rejection notice to file the actual lawsuit, under Government Code section 945.6.

The takeaway: if you were hurt in a pothole accident in San Diego, the calendar is your enemy. Talk with a lawyer in days, not months.

​

How to File a Claim Against the City of San Diego or Caltrans

The mechanics of presenting a claim depend on which agency owned the road. The most important thing is to use the right form, send it to the right office, and include the right supporting documents.

For city streets, the form is the City of San Diego's Claim Against the City of San Diego (Form RM-9). The Risk Management Department publishes the form and its general claim FAQ online. The claim is filed with:

City of San Diego Risk Management Department
1200 Third Avenue, 10th Floor
San Diego, CA 92101
(619) 236-6670

There is no filing fee. The department asks for at least 45 days to process a claim. Strong claims include:

• Photographs of the pothole, the surrounding pavement, and the damage to the vehicle, bicycle, or motorcycle.
• A police or incident report, if one was created.
• Repair estimates or paid invoices for property damage.
• Itemized medical bills and treatment records for injuries.
• A short factual statement describing what happened, where, and when.

For state highways, the claim goes to the California Department of General Services, not Caltrans directly, although Caltrans is the responsible agency. The Government Claims Program handles claims against state agencies and uses its own claim form. Caltrans also publishes information about how it handles pothole and roadway damage claims on its public-facing website. The six-month deadline and the same supporting-document checklist apply.

For unincorporated county roads, the claim goes to the County of San Diego's Office of County Counsel, which handles risk management for the County.

One trap to avoid: filing with the wrong agency does not stop the clock. A claim mailed to the city for a freeway crash does not preserve a claim against Caltrans. Identifying the right defendant up front is part of why this work is best done with counsel.

​

Pothole Injury Claims Are Different From Property Damage Claims

It is worth being honest about the economics of pothole cases, because two very different conversations get lumped under the same label.

Property damage claims are usually small. A pothole that bends a rim, cracks a tire, or knocks a wheel out of alignment is a real problem, but the recoverable damages are limited to repair costs. When the notice requirement is hard to meet and the dollars are low, those claims often resolve through informal reimbursement, through a denied claim, or through small claims court. They are not, as a rule, cases that attorneys take on contingency.

Personal injury claims are a different story. When a pothole causes a motorcycle to go down, a bicyclist to be thrown from the bike, or a car to lose control hard enough to injure the occupants, the damages can include emergency care, surgery, rehabilitation, lost income, long-term care needs, and pain and suffering. Two-wheel riders are especially exposed. A pothole that a car barely notices can put a motorcyclist on the pavement in front of traffic, and the resulting injuries are often catastrophic. Our guide to road hazards and bicycle accidents in San Diego covers the same dynamic for cyclists.

The injury cases are also the ones where the notice fight is worth having. Pulling complaint records, building a timeline, and showing the city or Caltrans had every chance to fix the road takes work. That work is justified when the injuries are serious enough that the recovery will support it.

If the claim is property damage only, the realistic path is the city or Caltrans claim process, and possibly small claims court if the claim is denied. If the claim involves a real injury, the path runs through a personal injury attorney who handles government-defendant cases.

What to Do After a Pothole Accident in San Diego

The first hours after a pothole crash quietly decide the strength of the claim that follows. A few practical steps make a large difference later.

1. Get to safety and call 911 if anyone is hurt. Even injuries that feel minor at the scene can mask concussion, internal injury, or spinal trauma. Always be evaluated.
2. Photograph the pothole in detail. Capture the size, depth, location relative to lane markings, and any identifying features. Put a phone, shoe, or coin in one shot to give scale. Photograph the damaged vehicle, bicycle, or motorcycle from multiple angles.
3. Record the exact location. Use your phone's GPS to capture coordinates and cross-streets. The exact spot will matter when an attorney later determines whether the road belongs to the city, the state, or the county.
4. Ask for a police report. For crashes involving injury, SDPD or CHP can document the scene. The report becomes useful evidence later, even if the officer does not assign fault.
5. Identify witnesses. Get names and phone numbers from anyone who saw the crash, including following drivers, pedestrians, and nearby business employees.
6. Report the pothole, but do not give a statement on fault. Reporting through the City's Get It Done system or to Caltrans creates an official record. Keep the report factual and brief, and do not discuss fault, injuries, or what you think you should be paid.
7. See a doctor the same day if you can. A gap in treatment is the first thing an insurance adjuster will use to argue your injuries were not serious.
8. Save the damaged parts. Keep the blown tire, bent rim, or damaged frame. Physical evidence corroborates the size and force of the impact.
9. Talk to an attorney within days. The six-month clock has already started.

What you do not want to do is give a recorded statement to anyone before talking to a lawyer, post about the crash on social media, or accept a small early settlement from any insurer or claims representative.

How a San Diego Pothole Injury Case Actually Gets Built

A pothole injury case is built in a different order than a normal car crash case. The reason is the deadline and the notice problem. We work from the calendar backwards.

We start with jurisdiction. Within the first week we are pulling up parcel records, Caltrans right-of-way maps, and city maintenance districts to confirm exactly who owned the pavement at the point of impact. If the wrong agency gets named in the claim, the case is over before it begins.

We move fast on the notice investigation. Get It Done complaint records, prior crash reports, and maintenance logs are usually obtainable through public records requests, and the data is most useful when it is fresh. We have seen cases where a single screenshot from the city's own complaint database turned a denied claim into a serious settlement, because it proved that the city had been told about the pothole weeks before our client was hurt.

Some of the strongest notice evidence comes from the City's own pavement records. In one case, we represented a bicyclist who suffered a brain injury after striking a pothole. During the investigation we obtained photographs from the City's 2016 pavement condition assessment that captured the same pothole, in the same spot, long before the collision. That evidence established that the City had known about the dangerous condition, and had ample time to repair it, years before our client was hurt. The lesson is that the agency's own inspection program can become the proof that defeats its defense.

We preserve evidence quickly. The pothole itself often gets repaired within days of a serious crash, sometimes after a phone call from us asking the city about the location. That is good public safety, and it makes the photographs and measurements we took at the scene the only record of what the road looked like the moment our client was hurt.

And we are realistic about the case. Pothole cases are demanding. The defendants are agencies with real lawyers and real defenses, and the notice requirement gives them leverage. The cases that work are the ones where the injury is serious enough to justify the fight and the evidence on notice is strong enough to win it.
