Seattle Juvenile DUI Offenses

Washington has strict DUI laws for drivers under the age of 21. Even small amounts of alcohol or marijuana in a minor's system can result in criminal charges and license suspension.

If your child has been arrested for DUI in Seattle, early legal representation is critical. A juvenile DUI conviction can affect education, scholarships, employment opportunities, and future licensing.

Under 21 DUI Law in Washington (RCW 46.61.503)

Washington has a special “zero tolerance” law for drivers under 21.

Under RCW 46.61.503, a person under 21 may be charged with Underage DUI if:

  1. The driver was under 21 years old; AND
  2. Within two hours of driving, the driver had:
    • A blood alcohol concentration (BAC) of 0.02% or higher; OR
    • Any measurable amount of THC above the legal threshold for minors.

Unlike adult DUI cases, the State does not need to prove actual impairment under this statute. The presence of alcohol or marijuana above the statutory limit is enough.

An Under 21 DUI is generally charged as a misdemeanor offense.

Standard DUI Charges for Juveniles (RCW 46.61.502)

Juveniles can also be charged under the same DUI law that applies to adults.

Under RCW 46.61.502, a person — regardless of age — may be charged with DUI if they:

  • Have a BAC of 0.08% or higher within two hours of driving;
  • Have a THC concentration of 5.00 nanograms per milliliter or higher within two hours of driving; OR
  • Are under the influence of alcohol, marijuana, or any drug.

This offense is typically charged as a gross misdemeanor, even for drivers under 21.

Juvenile DUI Penalties in Seattle

Penalties vary depending on the charge, prior history, and specific facts of the case. Potential consequences may include:

  • Mandatory jail time
  • Fines and court costs
  • License suspension
  • Ignition interlock requirements
  • Alcohol or drug education programs
  • Probation supervision

In addition to criminal penalties, there is also an administrative license suspension through the Washington Department of Licensing. You have only 20 days from the date of arrest to request a hearing to challenge that suspension.

Long-Term Consequences of a Juvenile DUI

A DUI conviction can impact:

  • College admissions
  • Scholarship eligibility
  • Professional licensing
  • Military enlistment
  • Employment background checks

For young drivers, the long-term impact can be more damaging than the immediate penalties.

Defending Juvenile DUI Charges

Juvenile DUI cases often involve:

  • Challenging the legality of the traffic stop
  • Questioning breath or blood test procedures
  • Examining whether proper warnings were given
  • Reviewing field sobriety testing methods
  • Negotiating for reduced charges or diversion options

Because young drivers may have no prior record, early negotiation and strategic defense can significantly influence the outcome.
