There are some exceptions to the one or two year statute of limitation rule for minors and claims against public entities. Minors. If there was a minor involved in the accident who was also injured, a parent may pursue a claim on behalf of the child. Alternatively, the minor has until his or her 18th birthday, plus the statutory limit, to personally file suit. For example, in California, the statutory limit is two years for a personal injury lawsuit. A 14-year-old has about six years to file--that is, four years until the teen's 18th birthday plus the two year statute of limitations.

Public entities. Time periods are much stricter when you have a claim against a public entity, as when you're injured on board a city bus. The city may give as little as three months from the accident to file a claim. Consult a car accident attorney right away to cut through the red tape.
