The statute of limitations is the first and most unforgiving rule in personal-injury practice. Miss it by one day, and a meritorious case becomes worthless. Yet it is the rule that unrepresented plaintiffs most often misunderstand, in part because the deadline that matters depends on the defendant, the injury type, and the jurisdiction.
This guide covers the general personal-injury SOL by state and then walks through the four common ways the clock gets tolled, accelerated, or interrupted.
The basic deadline by state
Every state sets its own filing deadline. The personal-injury SOL controls the time within which a lawsuit must be filed in court. Filing a claim with an insurance carrier does not stop the SOL clock. Settlement negotiations do not stop the clock. Only filing a properly-served lawsuit stops the clock.
The general personal-injury SOL by state (verified against state code, see the state pages on this site for each citation):
- One year: Kentucky, Louisiana, Tennessee
- Two years: Alabama, Alaska, Arizona, California, Colorado, Connecticut, Delaware, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Minnesota (general), Nevada, New Jersey, Ohio, Oklahoma, Oregon, Pennsylvania, Texas, Virginia, West Virginia
- Three years: Arkansas, District of Columbia, Maryland, Massachusetts, Michigan, Mississippi, Montana, New Hampshire, New Mexico, New York, North Carolina, Rhode Island, South Carolina, South Dakota, Vermont, Washington, Wisconsin
- Four years: Florida (changed from four to two years for cases accruing after March 24, 2023), Nebraska, Utah, Wyoming
- Five years: Missouri
- Six years: Maine, Minnesota (assault and battery only), North Dakota
Florida is the recent change worth flagging. House Bill 837 reduced the SOL for negligence-based personal-injury claims accruing after March 24, 2023 from four years to two years. Cases that accrued before that date keep the four-year deadline. Cases accruing after, get two years.
Four ways the clock gets modified
1. The discovery rule
The clock typically starts on the date the injury occurred. In most car-accident cases, that is the date of the crash. The discovery rule is an exception: it starts the clock on the date the plaintiff discovered or, through reasonable diligence, should have discovered the injury.
The discovery rule is used most often in:
- Medical malpractice cases where the negligent act and the resulting injury are temporally separated (a misread x-ray that goes undiscovered until symptoms emerge years later)
- Toxic exposure cases where the disease manifests years after exposure (asbestos mesothelioma, environmental contamination)
- Product liability cases where a latent defect is not discovered until failure
The discovery rule rarely applies in motor-vehicle cases. If your back hurts the day after a crash, the clock started on the day of the crash even if the disc herniation was not radiologically confirmed until weeks later. Courts treat the symptoms as the discovery, not the radiologist’s report.
2. Tolling for minority
If the plaintiff was a minor at the time of injury, most states pause the SOL until the minor reaches the age of majority (typically 18). The clock then runs for the full SOL period from the date of majority. A 12-year-old injured in a state with a three-year SOL has until age 21 to file.
Some states cap the total toll. California Civil Procedure Code section 352, for example, tolls the SOL during minority but only up to age 18 plus the standard two-year SOL, ending at age 20. Other states allow the full statutory tolling.
3. Tolling for mental incapacity
Most states pause the clock during periods of legal mental incapacity. The standard is high: not merely depressed or grieving, but unable to understand the nature of legal rights. The tolling ends when the incapacity ends.
This applies most often in cases involving severe traumatic brain injury, where the plaintiff was rendered unable to manage their own affairs for a period of time after the injury.
4. Fraudulent concealment
If the defendant actively concealed the cause of the injury, most states pause the clock until the concealment is discovered or could reasonably have been discovered. This applies in product liability cases where the manufacturer hid evidence of a defect, in medical malpractice cases where the doctor altered records, and in occasional fraud-adjacent cases.
The plaintiff must prove concealment by clear and convincing evidence. This is a high bar.
The shorter deadlines that catch unrepresented plaintiffs
The general PI SOL is the headline number. Three other deadlines kill more cases than the SOL itself.
Government tort claim notice deadlines
When the at-fault party is a state or local government entity, you must file a written notice of claim before suing. The notice deadline is shorter than the SOL, typically 60 to 180 days from the date of injury. Examples:
- California: 6 months for state agency, 6 months for municipal (Cal. Gov. Code section 911.2)
- New York: 90 days (Gen. Mun. Law section 50-e)
- Washington: 60 days plus a 60-day waiting period before suit (Rev. Code section 4.96.020)
- Mississippi: 90 days (Miss. Code section 11-46-11)
- Florida: 3 years for state, but 180 days notice required to specific agencies (Fla. Stat. section 768.28)
Missing the notice deadline bars the claim even if the general SOL has not expired. See the government-claim-notice tool on this site for the deadline in every state.
Insurance contract deadlines
Most personal auto-insurance policies impose a one-year contractual deadline for uninsured-motorist and underinsured-motorist claims. This is a contract-of-adhesion clause that runs from the date of loss, regardless of the state SOL. Treat the one-year contractual deadline as the operative deadline in UM/UIM matters.
Discovery and conditions precedent
Some states have additional procedural prerequisites that, if not satisfied within the SOL, bar the claim. Medical-malpractice cases in particular often require:
- A pre-suit notice of intent to sue (Florida, Georgia, others)
- An affidavit or certificate of merit from a qualified expert (most states)
- A pre-suit panel review or arbitration (some states)
If the SOL is approaching and the plaintiff has not yet satisfied the conditions precedent, the case may be barred.
Practical implications
For the unrepresented plaintiff:
- Count days, not months. A two-year SOL on a March 15, 2025 injury runs to March 15, 2027 at midnight. Day 731 is too late.
- File the lawsuit. Do not file an insurance claim and assume that is the same thing. It is not. Only filing in court stops the clock.
- Check the government-claim-notice deadline first. If the at-fault party might be a government employee, on duty, or in a government vehicle, the 60-180 day notice deadline kicks in immediately.
- For UM/UIM claims, check your auto policy’s contractual deadline. Usually one year. Treat it as the operative deadline.
- Get the calculation in writing from a lawyer if the case is close to deadline. Most lawyers offer free SOL analysis on PI cases. Calling a lawyer 10 days before the deadline is dangerous; calling 60 days before is fine.
The SOL countdown tool on this site applies these rules to your state and your injury date. Treat it as a starting point, not a substitute for verifying the deadline against the actual state code citation.
