Ohio recorded 264,954 traffic crashes in 2025, the most recent full year on record, and another 26,533 in December 2025 alone12. Every one of those crashes started a clock. Miss it, and an insurer can stop negotiating and a judge can throw the case out, no matter how clear the fault or how serious the injury.
The two-year deadline
In Ohio, a claim for bodily injury from a car accident has to be filed within two years of the date the crash happened. That's the rule under Ohio Revised Code 2305.10, which sets the same two-year window for injury to a person and for damage to property3. So if the only loss is a totaled car or a cracked bumper, the deadline is identical to the deadline for a broken leg: two years, no more.
The clock starts on the date of the crash, not the date a doctor finally diagnoses a herniated disc or a torn labrum. Ohio's accrual rule for this kind of claim runs from when "the injury or loss to person or property occurs"3, and a car crash counts as an injury that happens immediately, not one discovered later the way some latent-exposure claims work. Waiting to see if an injury heals on its own before talking to a lawyer eats directly into the two years.
When the clock pauses
A few things can stop or delay that two-year countdown.
Ohio Revised Code 2305.16 tolls the statute of limitations for anyone who was a minor or of unsound mind when the crash happened4. In practice, a child hurt in a crash doesn't lose the right to sue on their 18th birthday. The two-year clock doesn't start until the disability, meaning minority, ends, so someone injured as a child generally has until two years after turning 18, roughly their 20th birthday, to file, no matter how old they were when the crash occurred. The same tolling applies to someone who was of unsound mind at the time, until that condition is legally removed. It doesn't extend a parent's own separate claim for a child's medical bills, which still runs on its own two-year clock from the date of the crash.
The clock can also pause if the at-fault driver leaves Ohio or hides afterward. Under Ohio Revised Code 2305.15, time the driver spends out of state or concealed doesn't count toward the two years5. That matters more than it might seem: out-of-state drivers and rideshare or delivery drivers who relocate are common enough in Ohio crash claims that this provision comes up regularly.
If the crash turns into a death
Ohio treats wrongful death as its own claim with its own clock. Under Ohio Revised Code 2125.02, a wrongful death lawsuit must be filed within two years of the date of death, not the date of the crash6. That distinction matters when someone survives an accident for weeks or months before succumbing to their injuries. The family's two years starts on the date of death, separate from whatever deadline applied to the injury claim itself.
Suing a government driver or agency
If a snowplow, transit bus, police cruiser, or ODOT vehicle caused the wreck, different rules layer on top of the standard two years.
Claims against a city, county, township, or other political subdivision still run on a two-year clock under Ohio Revised Code 2744.047. But subdivision immunity under Chapter 2744 can bar the claim entirely unless it fits a specific statutory exception, such as negligent operation of a motor vehicle by an employee. That's a fault question as much as a timing one, and it's worth having an attorney look at it early rather than close to the deadline.
Claims against the State of Ohio itself, say an ODOT plow driver or a state trooper, go through the Ohio Court of Claims. Ohio Revised Code 2743.16 sets the same two years to file8, but adds an extra step: before suing, a claimant generally has to attempt to get the claim compromised through the state's Office of Risk Management. The statute requires the state to respond at least 60 days before the two-year deadline expires, and time spent in that settlement process doesn't count against the two years8. Skipping that step, or misjudging how much of the window it uses up, is a common way these claims run into trouble.
Your own insurer runs on a different clock
Uninsured and underinsured motorist (UM/UIM) coverage isn't required in Ohio. Since a 2013 amendment to Ohio Revised Code 3937.18, insurers don't even have to offer it, so whether a policy includes UM/UIM at all depends on what was bought9. If it's there, and the at-fault driver was uninsured or underinsured, the claim runs against the policyholder's own insurance company rather than the other driver, and it's a contract claim, not a tort claim.
That distinction lets insurers write their own deadline into the policy, and Ohio courts enforce it. In Barbee v. Nationwide Mutual Insurance Co., the Ohio Supreme Court upheld a policy provision requiring a UIM lawsuit to be filed within three years of the accident, rejecting the argument that the clock should instead start once the at-fault driver's liability limits were exhausted10. Three years is a common contractual window in Ohio auto policies, but it isn't universal. Check the declarations page for a "legal action" or "suit against us" clause rather than assuming the deadline matches the two-year tort rule, or even the three-year figure from that case.
Comparative fault raises the cost of waiting
Ohio is a modified comparative negligence state: a driver found 51% or more at fault for the crash recovers nothing, and any recovery below that line is reduced by the driver's own share of fault, under Ohio Revised Code 2315.3311. Filing near the deadline leaves little time to gather the crash report, witness statements, and vehicle data that often decide how fault gets split. The official report is available through the Ohio State Highway Patrol's portal; see our Ohio crash reports page for how to pull a copy.
Related claims and getting help
None of these deadlines move on their own. Adjusters know the two-year date sitting on a file and have little reason to negotiate seriously until it's close, and once it passes, Ohio courts have no discretion to revive a claim that's time-barred. A vehicle that lost resale value beyond the repair cost is a separate claim worth tracking down before the same two-year window closes; our Ohio diminished value guide covers how that works. If a minor, a death, a government vehicle, or a UM/UIM claim is part of the picture, it's worth getting a personal injury attorney's read on the specific dates well before the deadline arrives, not after.
