Many drivers are confused about the difference between DUI vs DWI in Washington State. Although some states treat DUI (Driving Under the Influence) and DWI (Driving While Intoxicated) as separate charges, Washington law does not make this distinction. In Washington State, DUI is the primary legal term used for impaired driving offenses, whether the impairment is caused by alcohol, marijuana, or another substance.
At Blanford Law, we help drivers across Washington understand their rights and legal options when facing DUI charges.

DUI Charges in Washington State
Under RCW 46.61.502, a DUI occurs when a driver operates a vehicle with a blood alcohol concentration (BAC) of 0.08% or higher, or while impaired by alcohol or drugs.
There is no separate DWI charge in Washington — all impairment-related offenses are charged under the DUI statute. The penalties for a DUI conviction can include:
- Jail time
- Fines and court costs
- Driver’s license suspension
- Mandatory ignition interlock device
- Alcohol or drug treatment programs
The consequences of a DUI vs DWI conviction in Washington State are severe, even for first-time offenders.
Understanding the Role of Impairment
Whether the impairment is caused by alcohol, prescription drugs, marijuana, or illegal substances, Washington law treats all forms of impaired driving under the same DUI umbrella.
In states that use the DWI term, it sometimes reflects a higher BAC or more serious impairment. In Washington, the focus is solely on the driver’s ability to operate safely.
Legal Differences: DUI vs DWI Outside Washington
In other states, the distinction between DUI and DWI may affect how the charges are filed or the penalties imposed. However, in Washington State, the DUI statute covers all situations where impairment affects a driver’s ability to safely operate a vehicle.
If you hear the term DWI used informally in Washington, it is generally interchangeable with DUI — but the official legal charge will always be DUI.
