Two years — but the government clock is far shorter
Oklahoma gives most personal injury and wrongful death lawsuits two years (12 O.S. 95; wrongful death runs from the date of death). But if a government entity is involved — a city vehicle, a school bus, a state road defect — the Governmental Tort Claims Act requires a written notice of claim within one year, the claim is deemed denied if not approved within 90 days, and suit must follow within 180 days of denial — with damages capped by statute. Two clocks, both short. Waiting is costly either way: witnesses scatter and video gets erased.
The 51% bar: modified comparative negligence
Oklahoma follows modified comparative negligence (23 O.S. 13-14): you can recover as long as your share of fault is not greater than the combined fault of those you're suing — with any award reduced by your percentage. Cross 51% and recovery is barred. It's exactly why insurers push so hard to shift blame onto you, especially in storm and hail crashes where 'you should have slowed down' is their favorite argument.
Dogs and motorcycles
Oklahoma's dog-bite statute (4 O.S. 42.1) imposes strict liability for an unprovoked bite when the victim was lawfully present — and by its own exception, it does not reach rural areas, which run on negligence and one-bite principles instead. For riders, lane splitting is illegal in Oklahoma (47 O.S. 11-1103), and helmets are required for riders under 18.
Reporting a crash — and where the trauma centers are
Oklahoma requires immediate notice to police for a crash involving injury or death, and the state's minimum liability limits (25/50/25) are low enough that serious injuries often exceed the at-fault driver's policy. A fact worth knowing: Oklahoma's Level I trauma map changed in 2025 — OU Medical Center in Oklahoma City and both Saint Francis Hospital and Ascension St. John in Tulsa now hold Level I verification. On any claim, a participating Oklahoma law firm can review it for free at the Oklahoma personal injury hub.

What if I was partly at fault?
