Washington "DUI" Attachment is a type of court order used in the state of Washington. It is issued as a result of a driving under the influence (DUI) conviction. The order attaches the DUI conviction to the offender's driver's license for the duration of the sentence. It requires the offender to comply with all the penalties and conditions imposed by the court, including fines, probation, alcohol/drug education, community service, and license suspension. Additionally, the DUI Attachment will remain on the offender's record for at least three years, and may be seen by employers in a background check. There are two types of Washington "DUI" Attachment: an ignition interlock device (DID) attachment and an alcohol/drug assessment and treatment attachment. The DID attachment requires the offender to install an ignition interlock device on their vehicle, which measures the driver's blood alcohol content (BAC). The alcohol/drug assessment and treatment attachment requires the offender to complete an evaluation and treatment program and submit to periodic testing for alcohol and/or drugs.
