Suing the Government for a Dangerous Road in California

A government agency can be held legally responsible when a dangerous condition of a public road causes a crash. These claims are not ordinary negligence cases. They are governed by the California Government Claims Act, which sets specific elements a plaintiff must prove, gives public entities defenses that private defendants do not have, and imposes a claim deadline far shorter than the usual two years. Understanding that framework is the difference between a viable claim and one that is barred before it begins.

This article explains when a public entity is liable for a dangerous roadway under California law, what qualifies as a dangerous condition, the central role of notice, the evidence and public records that prove these cases, the defenses the government will raise, and the deadlines that control the claim.

​

The Short Version

• Public entities can be liable for dangerous roads, but only under the specific elements of Government Code section 835, not general negligence.
• There are two routes to liability: a public employee negligently created the hazard while acting within the scope of employment, or the entity had notice of the hazard and a reasonable time to fix it.
• Notice usually decides the case. Most claims turn on proving the agency knew, or should have known, about the danger before the crash.
• The evidence is documentary. Collision histories, design plans, maintenance records, and prior complaints, obtained through public records requests, are what win these claims.
• Design immunity is the main defense, and it can be overcome in defined ways.
• A government claim is due within six months of the crash, not two years.

​

The Legal Standard: Government Code Section 835

Liability for a dangerous condition of public property is defined by California Government Code section 835. The elements a jury must find are set out in the Judicial Council's pattern instruction, CACI No. 1100. To recover, an injured person must prove each of the following:

• The public entity owned or controlled the property.
• The property was in a dangerous condition at the time of the injury.
• The dangerous condition created a reasonably foreseeable risk of the kind of injury that occurred.
• Either a negligent or wrongful act of a public employee acting within the scope of employment created the condition, or the entity had notice of the condition long enough before the injury to have protected against it.
• The plaintiff was harmed, and the dangerous condition was a substantial factor in causing that harm.

The fourth element is where most of the legal contest happens, because it sets out the two separate routes to holding a public entity responsible. Each is addressed below.

​

What Qualifies as a "Dangerous Condition"

A dangerous condition has a precise statutory meaning. Under Government Code section 830 and CACI No. 1102, it is a condition of property that creates a substantial risk of injury when the property is used with reasonable care in a reasonably foreseeable way. A condition that poses only a minor, trivial, or insignificant risk does not qualify, and California courts will dismiss claims based on trivial defects as a matter of law. A shallow surface crack is generally trivial; a pothole deep enough to throw a motorcyclist or a washed-out shoulder on a high-speed highway is not.

One distinction matters in roadway cases. A dangerous condition requires a physical defect in the property itself. The negligent act of another driver, standing alone, is not a dangerous condition of public property. The property is actionable when a physical feature of the road, its design, signage, sight lines, or surface, creates or increases the risk, including the risk posed by foreseeable driver error. Common examples include defective intersection or interchange design, missing or downed signage, obscured sight lines, shoulder drop-offs, missing guardrails, and inadequate drainage that floods a travel lane.

​

Route One: A Public Employee Created the Hazard

The first route to liability applies when a public employee created the dangerous condition. This route is narrower than it first appears. The entity is responsible only if the employee's act or omission was negligent or wrongful and the employee was acting within the scope of employment when it occurred. A maintenance crew that repaved a lane improperly, or a work crew that left an unmarked drop-off, can satisfy this route. Conduct outside the scope of employment does not bind the entity under this prong, which is why many roadway claims proceed instead on the second route, notice.

​

Route Two: Notice of the Dangerous Condition

When no public employee created the hazard, the injured person must prove the entity had notice of the dangerous condition in time to address it. Government Code section 835.2 and CACI No. 1103 recognize two forms of notice:

• Actual notice exists when the entity knew the condition existed and knew, or should have known, that it was dangerous. Prior complaints, prior crash reports, and internal work orders are the classic proof.
• Constructive notice exists when the condition was obvious and had existed long enough that a reasonably adequate inspection program would have discovered it. The question becomes whether the entity had, and actually used, a reasonable inspection system.

Notice is the element on which most dangerous-roadway claims succeed or fail, and it is proven with records rather than testimony alone.

​

Proving the Case: Collision Data and Public Records

Because notice and the dangerous condition itself are established through documents, the investigation centers on obtaining the right records before they change or are lost.

Collision history at the location is often the strongest evidence that a condition was dangerous and that the entity was on notice. California collision data is collected in the California Highway Patrol's Statewide Integrated Traffic Records System (SWITRS), and that data is mapped and made searchable through the Transportation Injury Mapping System (TIMS) maintained by U.C. Berkeley. A documented pattern of similar crashes at the same location supports both that the condition was dangerous and that the entity should have known.

The remaining records are obtained through the California Public Records Act. Targeted requests to the responsible agency can produce the roadway design and as-built plans, the traffic and engineering studies for the location, maintenance and inspection logs, work orders, and the prior complaints residents filed about the condition. In San Diego, resident reports submitted through the City's Get It Done system frequently establish that the City was told about a hazard well before a crash. Pulling these records early, while they are still retained, is the core of building one of these cases, and it usually requires accident-reconstruction or civil-engineering experts to interpret and present them. A San Diego dangerous roadway attorney moves quickly to obtain and preserve this evidence before it changes.

​

The Government's Defenses, and Their Limits

Public entities have defenses unavailable to private defendants. The most significant in roadway cases is design immunity under Government Code section 830.6 and CACI No. 1123. It can shield an entity from liability for a roadway's design where the design was approved in advance by an authorized public employee and there is substantial evidence supporting its reasonableness.

Design immunity is significant but not absolute. It can be overcome in three principal ways:

• Failure to warn of a known danger. Even with an approved design, the entity retains a duty to warn of a concealed danger the road creates. An entity that learns an approved design is producing crashes and does not warn may lose the protection.
• Loss of design immunity from changed physical conditions. Under CACI No. 1124 and the California Supreme Court's decision in Cornette v. Department of Transportation, immunity is lost when the design has become dangerous because of a change in physical conditions, the entity had notice of that danger, and it had a reasonable time to correct the condition or warn of it.
• Conditions that do not conform to the approved plan. Immunity protects the design as approved, not deviations from it. Where the conditions that caused the danger did not comply with the plan, such as signage, striping, or other features that were not built or maintained as designed, the immunity does not apply.

Which, if any, of these applies is an evidence-intensive question decided on the design records, the collision history, and expert analysis.

The Claim Requirement and the Six-Month Deadline

Before suing a public entity, an injured person must first present a written claim to that entity. Under Government Code section 911.2, a claim for personal injury must be presented within six months of the date of the injury. This is one-quarter of the standard two-year deadline that applies to ordinary injury claims, and missing it generally bars the case. A late-claim application is possible within a year but is granted only for limited reasons.

Presenting the claim is a prerequisite to suit. Under Government Code section 945.4, a lawsuit cannot be filed until the entity has acted on the claim or is deemed to have rejected it. Identifying the correct entity is essential, because a city street, a county road, a state highway maintained by Caltrans, and a private road each carry different responsibility, and presenting the claim to the wrong agency does not preserve the claim. If a state highway was involved, our guide to suing Caltrans after a California accident covers the state's process; when the hazard is an intersection, see our guide to dangerous intersection accidents; and for cyclists specifically, our overview of suing government entities after a bicycle crash applies the same framework. These hazards frequently concentrate on San Diego's most dangerous roads, and they injure cyclists through the road hazards covered here. The same six-month framework governs a San Diego pothole claim.
