In Oregon, the statute of limitations for an adult is two years for a personal injury claim caused by a car accident. This means if your claim is not settled or a lawsuit filed within two years of the collision, then all of your rights are lost.
For minors the statute of limitations is 7 years from the date of the collision, or their 19th birthday — whichever comes first.
There are numerous statutes that require written notice within 180 days of an injury — such as an injury caused by a city, county, state or federal employee.
