What Qualifies as a Fourth DUI in Washington State

In Washington, a DUI is escalated to a felony if it is your fourth DUI-related conviction within your lifetime. Unlike many states that only look back a certain number of years, Washington employs a lifetime lookback approach, meaning older convictions may still count toward the total. This strict interpretation significantly heightens your exposure to felony charges.
The law applies not only to prior DUI charges but also includes:

DUI convictions from Washington or other states

Reckless or negligent driving convictions reduced from DUI

Physical control convictions

Any convictions involving impaired driving due to alcohol or drugs

Why a Fourth DUI Becomes a Felony Under RCW 46.61.5055

Per RCW 46.61.5055, a fourth offense DUI is automatically elevated to a felony. This classification brings your case under Superior Court jurisdiction, where procedural formality is stricter, and the prosecution is often less lenient.

This felony is designated a Class C felony, with a seriousness level of V under Washington's sentencing guidelines. Your prior record influences the offender score, which can dramatically increase the minimum sentencing range, sometimes reaching up to 29 months in state prison.

Deferred Prosecution for Fourth Offense DUI

While deferred prosecution is typically reserved for 2nd Offense offenders, it may still be an option under specific conditions:

You haven't used deferred prosecution before

You are diagnosed with a substance use or mental health disorder that contributed to the DUI

You agree to intensive treatment, sobriety, and five years of supervision

However, courts are reluctant to offer this option in fourth DUI cases. Judges and prosecutors tend to view repeated offenses as disqualifying for treatment alternatives.

Legal Defense Strategies That Can Matter

Effective defense strategies may still mitigate or dismiss charges. Your attorney may:

Challenge legality of the traffic stop

Scrutinize field sobriety test conditions

Dispute breath or blood test accuracy

Raise chain of custody or evidence admissibility issues

Argue constitutional rights violations (e.g., Miranda, search & seizure)
