How long does the Prosecutor have to file my DUI case?

Two (2) years. The Statue 0f Limitations is the absolute “deadline” for filing on your specific offense. The time period in which a DUI case can be filed is two (2) years from the date of arrest. That said, a lot of cases have been delayed because they are blood draw cases. The Washington State Tox Lab is approximately 6-12 months behind on getting the blood results back to law enforcement.
