Vehicle Requirements for Interlocks

Ignition Interlock Device Laws

  • Washington ignition interlock device laws state that anyone convicted of DUI must install an interlock device in any vehicle that he or she operates. The length of time that the device must remain installed varies depending on the conviction history of the offender.
  • A first-time offender whose BAC was above .08% but under .15% at the time of arrest must use the device for at least one year following a 90-day suspension.
  • If a first-time offender’s BAC was .15% or higher, the suspension period is one year.
  • A second-time offender with a BAC under .15% faces suspension of one year and an interlock period of at least one year.
  • An offender may apply for an exemption for employer-owned vehicles not equipped with an interlock device, but the offender may only drive such a vehicle during work hours.
  • If second-time offender’s driver’s BAC was above .15%, the suspension is two years.
  • For third offenses, the interlock period is also at least one year, but suspensions are either three or four years, depending on BAC level.
