A real, genuine extension to two years
Under T.C.A. § 28-3-104(a)(2), Tennessee's otherwise strict one-year personal injury deadline extends to two years when the conduct giving rise to the civil claim is also the subject of a criminal prosecution commenced within one year by a law enforcement officer. This is a genuinely real extension, not a theoretical one — it has been applied in actual cases.
But genuinely narrower than it sounds
Here's the real catch. Tennessee courts have repeatedly held that this extension requires an actual criminal prosecution, not merely a traffic citation or a municipal ordinance violation. In one documented case, a city ordinance citation for the same accident was found insufficient to trigger the two-year extension — the plaintiff's claim remained subject to the standard one-year deadline, and was dismissed as untimely.
A genuinely frequently litigated question
This isn't a one-off dispute. Multiple Tennessee Court of Appeals cases have specifically litigated whether a particular citation or charge against a defendant met the standard for this extension — suggesting that relying on this provision without confirming the exact nature of any criminal charges involved is a genuinely risky assumption.
The ordinary discovery rule
Outside of this specific extension, Tennessee's general discovery rule starts the one-year clock when the plaintiff knew, or reasonably should have known, that they had sustained an injury as a result of the defendant's wrongful conduct — not necessarily the exact date of the underlying incident.
Medical malpractice: discovery with a real ceiling
Medical malpractice claims follow a related but distinct framework under T.C.A. § 29-26-116: if the injury isn't discovered within the standard one-year period, the deadline becomes one year from discovery — but in no event more than three years from the date of the act itself, a genuine absolute outer limit regardless of when discovery actually occurs.
