3rd DUI Offense in Seattle
A third DUI in Washington is extremely serious. If you have been arrested for a third DUI within seven years of two prior DUI-related offenses, you are facing mandatory jail time, long-term license revocation, and significant financial penalties.
You also have only 20 days from the date of arrest to request a Department of Licensing (DOL) hearing to challenge your license suspension. If you miss this deadline, your license will be automatically revoked — even before your criminal case is resolved.
Washington Third DUI Laws (RCW 46.61.5055)
A third DUI within 7 years triggers enhanced mandatory penalties under Washington law. Prior offenses include convictions for:
- RCW 46.61.502 – Driving Under the Influence
- RCW 46.61.504 – Physical Control of a Vehicle Under the Influence
Both statutes apply if a person:
- Has a BAC of 0.08% or higher
- Has a THC concentration of 5.00 or higher
- Is impaired by alcohol, marijuana, or any drug

When Does a Third DUI Become a Felony?
A DUI becomes a Class B felony if:
- You have four or more prior DUI-related offenses within 10 years, OR
- You have a prior conviction for vehicular homicide or vehicular assault involving DUI.
If your current charge qualifies as a felony DUI, you could face state prison time instead of county jail.
Consequences Beyond Jail Time
A third DUI conviction can affect:
- Your employment and professional licenses
- Commercial driver's license (CDL) status
- Insurance rates
- Custody and family court matters
- Background checks
The court will treat a third DUI as a serious repeat offense, and prosecutors often pursue these cases aggressively.
Defending a Third DUI Charge in Seattle
Even with two prior convictions, the State must still prove the new DUI beyond a reasonable doubt. Defense strategies may include:
