Yes, You Can Bring a Claim Against the State
Many injured drivers assume the State of California cannot be sued. That is a myth. California law allows you to seek compensation from Caltrans and other public agencies when a dangerous road condition causes your injury, but the law sets strict rules for how and when you do it.
The most important rule is the clock.
If a government agency may share responsibility for your crash, you generally have only six months to present a formal written claim. That window is far shorter than the two-year deadline that applies to most California injury lawsuits. Roadwork crashes often involve both a public agency and a private contractor, so you may face two different deadlines and two different sets of rules at the same time.
This guide walks through who may be responsible, what the law requires you to prove, and the steps you can take now to protect your rights.
Who May Be Responsible for a Roadwork Crash
A construction zone on a California highway usually involves several parties. Each one may carry a different share of responsibility, and each one answers to different legal rules.
- Caltrans. The California Department of Transportation manages the state highway system. It designs projects, sets standards for temporary traffic control, and oversees work zones on state routes.
- Cities and counties. Local streets and county roads belong to local agencies, not the state. A crash on a city street under repair usually points to the city, its contractor, or both.
- General contractors. Private construction companies often perform the actual work under contract. They frequently handle the day-to-day setup of cones, barriers, signs, and lane closures.
- Subcontractors. Traffic control companies, paving crews, and hauling companies may each play a role in the conditions you encountered.
- Other drivers. A distracted driver or a truck carrying an unsecured load can contribute to a crash inside a work zone.
Identifying the right parties early matters. The law holds a public agency and a private company to different standards, and naming the wrong defendant, or missing one entirely, can weaken your case.
What Makes a Work Zone Legally “Dangerous”
California law does not hold an agency responsible for every imperfection in the road. 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 people use the property with due care in a reasonably foreseeable way.
Roadwork conditions that may meet this standard include:
- Unmarked or poorly marked lane closures that give drivers little warning before traffic must merge
- Missing, knocked-over, or blocked warning signs ahead of a work zone
- Sudden pavement drop-offs or uneven lanes left between paving stages
- Confusing lane shifts where old striping still shows through the new lane lines
- Construction debris, loose gravel, or steel plates left in or near travel lanes
- Inadequate lighting or reflective devices during nighttime work
Work zones in California must follow the California Manual on Uniform Traffic Control Devices (CA MUTCD). Part 6 of the manual governs temporary traffic control for construction and maintenance work. Work zones must comply with the edition of the CA MUTCD in effect at the time of the crash, so the applicable standards depend on when your collision happened.
When a work zone falls short of these standards, that gap may become important evidence in your claim.
The Six-Month Claim Rule for Caltrans and Other Public Agencies
Before you can file a lawsuit against a California public entity, you generally must present a written claim to that agency first. This requirement comes from the Government Claims Act, and courts apply it strictly.
The process typically works like this:
- Present your claim within six months. Government Code section 911.2 requires claims for personal injury or death to be presented no later than six months after the cause of action accrues, which is usually the date of the crash.
- Send it to the correct office. Claims against the State of California generally go to the Department of General Services, Office of Risk and Insurance Management, Government Claims Program. Caltrans accepts some smaller claims directly, but a serious injury claim usually follows the state program. Claims against a city or county go to that local agency.
- Include the details. The state’s claim form asks for specifics about where the incident happened, including the highway number and location. A vague or incomplete claim invites a challenge.
- Watch for the agency’s response. The agency may accept your claim, reject it, or take no action.
- File suit on time after a rejection. If the agency serves written notice that it rejected your claim, Government Code section 945.6 generally gives you six months from that notice to file a lawsuit. If the agency never sends written notice, a longer period may apply.
Six months passes quickly when you are focused on healing.
What if you already missed the deadline? The law allows you to apply for permission to present a late claim, generally within one year of the incident under Government Code section 911.4. The agency can deny that application, and courts grant relief only in limited circumstances. Do not count on this option as a safety net.
Holding Private Contractors Accountable
Private construction companies do not receive the same legal protections as government agencies. A claim against a contractor generally follows ordinary California negligence law, and the six-month government claim requirement does not apply to a private company. In most cases, you have two years from the date of injury to file a personal injury lawsuit under Code of Civil Procedure section 335.1.
To pursue a negligence claim against a contractor, you and your attorney generally need to show that:
- The contractor owed you a duty to use reasonable care in setting up and maintaining the work zone
- The contractor failed to meet that standard of care
- That failure caused your crash
- You suffered real harm as a result
Contractors often argue that they followed the traffic control plan exactly as the agency approved it. That argument can carry weight. Your attorney may need to compare the approved plan, the contract specifications, and the actual setup on the day of your crash. Gaps between the plan on paper and what crews did on the ground can make a real difference.
The relationship between agency and contractor also cuts the other way. Under Government Code section 815.4, a public entity may be liable for its independent contractor’s wrongful act or omission to the same extent a private person would be. That rule has a limit: the agency is not liable if it would have been immune had its own employee done the same thing. This overlap is one reason a roadwork case may name both the agency and the contractor.
Government Claims vs. Contractor Claims at a Glance
The rules for a public agency and a private company differ at nearly every stage.
| Issue | Claim Against Caltrans or a Public Agency | Claim Against a Private Contractor |
| Legal basis | Government Claims Act, including Gov. Code § 835 (dangerous condition of public property) | General negligence law |
| First step | Written government claim to the agency | Demand or lawsuit; no government claim required |
| Key deadline | Claim generally within 6 months (Gov. Code § 911.2) | Lawsuit generally within 2 years (Code Civ. Proc. § 335.1) |
| After the claim | Lawsuit generally within 6 months of a written rejection notice (Gov. Code § 945.6) | Not applicable |
| Notice | Unless an agency employee created the hazard, you may need to show the agency knew or should have known of it in time to act (Gov. Code § 835) | Focus is generally on whether the contractor acted reasonably |
| Common defenses | Design immunity, sign immunity, lack of notice, comparative fault | Compliance with approved plans, causation, comparative fault |
Deadlines can shift based on your specific facts. An attorney should confirm the dates that apply to you.
Defenses the Government and Contractors May Raise
Expect pushback. Public agencies have legal defenses that private parties do not, and they raise them often.
Design Immunity
Under Government Code section 830.6, an agency may avoid liability if it shows three things: the plan or design caused the accident, an authorized official approved the design in advance, and substantial evidence supports the design’s reasonableness. This defense has limits. In Cornette v. Department of Transportation (2001), the California Supreme Court explained that design immunity does not necessarily last forever, particularly when physical conditions change after an official approves the design.
Sign Immunity and the “Hidden Trap” Exception
Government Code section 830.8 generally protects agencies from liability for failing to post traffic or warning signs. That protection does not apply when a sign was necessary to warn of a dangerous condition that a careful driver would not reasonably notice or anticipate.
This exception matters in work zones, where hazards often appear suddenly. In Tansavatdi v. City of Rancho Palos Verdes (2023), the California Supreme Court held that design immunity does not automatically bar a claim that an agency failed to warn of a hidden danger.
Lack of Notice
Unless an agency employee created the hazard, the agency may argue that it had no actual or constructive notice of the condition in time to fix it. Complaint logs, maintenance work orders, and prior incident reports often become central to this fight.
Comparative Fault
Agencies and contractors frequently argue that you were speeding, distracted, or ignored posted signs. California follows a comparative fault system. If a jury finds that you share some responsibility, that finding typically reduces your recovery rather than eliminating it.
Steps to Protect Your Claim After a Roadwork Crash
Work zones change daily. Crews move cones, replace signs, and clear debris, sometimes within hours of a crash.
The scene you need to document may look completely different tomorrow.
If you can safely do so, consider these steps:
- Get medical care first. Your health comes before everything else, and prompt treatment also creates a record of your injuries.
- Call 911 or the CHP. On state highways, the California Highway Patrol typically responds and prepares a collision report.
- Photograph everything. Capture signs, gaps where signs should be, cones, barriers, lane markings, pavement edges, debris, lighting, and the position of your vehicle. Take both wide shots and close-ups.
- Note the exact location. Write down the highway number, direction of travel, nearest exit, and any mile markers you see. Government claim forms ask for this level of detail.
- Record the contractor’s name. Work trucks, equipment, and project signs often display the company name.
- Collect witness information. Other drivers and nearby workers may have noticed the conditions before your crash.
- Keep your records. Save medical bills, repair estimates, towing receipts, and notes about missed work.
- Be careful with insurance adjusters. An adjuster for a contractor or another driver may ask for a recorded statement soon after the crash. You can politely decline until you speak with a lawyer.
An attorney can also act quickly to preserve evidence you cannot reach on your own. This often includes sending preservation letters that ask the agency and contractor to keep traffic control plans, daily work logs, inspection records, and project photographs. Public records requests may reveal prior complaints or crashes at the same location.
Talk With a Lawyer Before the Deadline Passes
Roadwork crash claims combine government immunity rules, construction contracts, engineering standards, and tight deadlines. Every case turns on its own facts, and a claim that looks strong at first can still face serious defenses.
