How a Fourth DUI Is Different

In Washington State, a fourth DUI offense is no longer treated as a misdemeanor. Instead, it’s classified as a Class C felony, which carries significantly harsher penalties.

Why the Rules Change for a Fourth DUI

Washington uses a 10-year “look-back” system for DUIs, which means that every prior DUI conviction—regardless of when it occurred—can count toward your total. Starting in 2026, this changes to a 15-year “look back.” This approach reflects the state’s commitment to treating repeat offenses with increasing severity.

Even if it has been years since your last DUI, the cumulative weight of prior convictions influences how the court views your case. This could mean longer incarceration, heavier fines, and stricter monitoring requirements.

Penalties for a Fourth DUI in Washington State

The penalties for a fourth DUI conviction are life-altering. Here’s what you could face:

  • Felony Conviction: A fourth DUI is classified as a Class C felony, which carries long-term consequences, including restrictions on employment, housing, and voting rights.
  • Mandatory Incarceration: Felony DUIs come with mandatory jail time. The court may impose a lengthy prison sentence to deter future offenses.
  • Substantial Fines: Fines range up to $10,000. For many, this creates a significant financial strain, affecting both the individual and their family.
  • Driver’s License Revocation: A fourth DUI leads to at least a three year year revocation of your driver’s license, making daily life — work, school, or basic errands—an uphill battle.
  • Ignition Interlock Device (IID): After your driving privileges are reinstated, you’ll be required to use an IID anywhere up to ten years. This device requires you to pass a breathalyzer test before your car starts, preventing further impaired driving.
  • Probation and Alcohol Treatment:Probation terms often include mandatory participation in alcohol treatment programs, random testing, and compliance with strict court orders.
  • A Permanent Felony Record: A felony conviction becomes a permanent part of your record, limiting future opportunities in employment, housing, and more.

Legal Defense Strategies for a Fourth DUI

Being charged with a fourth DUI doesn’t mean you’re out of options. At Knauss Law, we craft personalized defense strategies tailored to the specifics of your case.

Some Knauss Law DUI Defense Strategies

  • Challenging the Stop: Was there reasonable suspicion or probable cause for the traffic stop? If not, any evidence gathered afterward could be deemed inadmissible.
  • Questioning BAC Results: Breathalyzers and blood tests are not foolproof. Calibration errors, improper use, or contamination can lead to inaccurate results.
  • Scrutinizing Procedural Errors: We carefully review the arrest process, evidence handling, and any administrative missteps to identify procedural violations that could work in your favor.
  • Presenting Mitigating Factors: Demonstrating that you’ve taken steps toward rehabilitation—such as completing alcohol treatment programs or participating in community service—can help reduce penalties.
  • Negotiating Plea Deals: In some cases, negotiating with prosecutors can result in reduced charges or alternative sentencing options, such as treatment programs instead of jail time.
