When a Road Condition May Support an Injury Claim

Potholes, missing signs and faded lane lines can cause serious crashes. Riders and cyclists face the greatest risk, but drivers can be hurt too. Dangerous road condition claims ask whether a public agency is responsible for an unsafe road. California law allows these claims, but it sets strict rules and short timelines.

This article explains the main rules, the evidence that tends to matter and the steps that come first. It stays general, because each road and each claim is different.

What Counts as a Dangerous Condition

Government Code section 830 defines a dangerous condition. In general, it means a condition of property that creates a substantial risk of injury when the property is used with due care in a reasonably foreseeable way. So the question is whether the road was unsafe for ordinary, careful users.

Minor defects may not qualify. Government Code section 830.2 says a condition is not dangerous if the risk was minor, trivial or insignificant, given the surrounding facts. That rule often comes up with small cracks or slight bumps.

The Main Rule for Dangerous Road Condition Claims

Government Code section 835 sets out when a public agency may be responsible. In general, the injured person must show:

  • The property was in a dangerous condition at the time of the injury.
  • The condition caused the injury.
  • That hazard created a foreseeable risk of the kind of injury that happened.
  • A public employee created the condition, or the agency had notice in time to fix it.

Each part needs proof. You can read Government Code section 835 on the state legislature site.

Notice Is Often the Key Issue

Many road hazards develop slowly. A pothole grows, or a sign fades. In these cases, the agency may not have created the problem. So the claim often depends on whether the agency had notice.

Actual notice means the agency knew about the hazard. For example, a resident reported the pothole through a city service line. Constructive notice means the hazard existed long enough, and was obvious enough, that the agency should have found it.

Public records can help show notice. Past complaints, work orders and inspection logs may all matter.

Design Immunity and Other Defenses

Agencies have defenses that private parties do not. Design immunity under Government Code section 830.6 can protect an agency when an approved plan created the condition. The rule has conditions, and courts read it closely.

Other defenses may apply to signs, signals and weather conditions. For instance, an agency may argue it lacked the time or funds to fix every hazard at once. These defenses can be technical.

Evidence in Dangerous Road Condition Claims

Evidence fades quickly on roads. Crews may fill a pothole within days. So prompt photos are very important. Useful evidence includes:

  • Photos of the hazard from several angles and distances.
  • An object next to the hazard to show its size.
  • The exact location, such as an address, cross street or pole number.
  • Photos of nearby signs, lighting and lane markings.
  • Damage to the vehicle, bike or gear.

Also record the weather and time of day. Then gather witness names and the report number.

Which Agency Owns the Road

Ownership decides who receives the claim. City streets usually belong to the city. County roads in unincorporated areas usually belong to the county. State highways and freeways usually belong to Caltrans.

However, some roads have shared or unusual ownership. The article on California government injury claims explains the claim process. Also check whether a private contractor was working on the road, since that may add another party.

Short Deadlines Apply

Claims against public agencies generally require a written claim first. Government Code section 911.2 generally calls for presenting a personal injury claim within six months after the claim arises. Then a lawsuit deadline follows after the agency acts.

These timelines are much shorter than many private claims. Because the applicable deadline depends on the facts and the parties involved, consider obtaining legal advice promptly.

Dangerous Road Condition Claims and Work Zones

Work zones create their own hazards. Lanes may shift, steel plates may cover trenches and loose gravel may cover the road. When a contractor is doing the work, it may share responsibility with the public agency.

So dangerous road condition claims in work zones may name more than one party. Contracts often say who must place signs and keep the road safe. Those documents usually come out later in a claim.

Photos of cones, signs and plates help show the layout at the time. Also note the name of any company on trucks or signs. In addition, a claim against a private contractor follows different timelines than a claim against an agency.

Reporting a Road Hazard

Reporting a hazard helps protect others. In the City of Sacramento, residents can report road problems through the city’s 311 service. State highways issues can go to Caltrans through its service request page.

A report is not a claim. However, a dated report can show notice for any later incident. Keep a copy or a confirmation number.

Motorcycles and Bicycles

Riders face higher risks from road hazards. A small pothole or gravel patch can cause a fall. The article on motorcycle crash evidence explains how to save evidence after a rider goes down.

The Sacramento public agency injuries hub lists more articles. When a road hazard causes serious injury, consider speaking with a qualified California personal injury attorney soon.
