The crime of ignition interlock device violation is defined under RCW 46.20.740 as operating a motor vehicle without a functional ignition interlock device when required by official DOL record. This charge is a gross misdemeanor offense and carries a maximum sentence of 364 days in jail in a $5,000 fine. Typically, this charge results when a driver has been convicted of a DUI (or related offense) and is found driving without an interlock device during the period of restriction following sentencing. A conviction for this charge can also carry possible mandatory minimum probation sentences under RCW 46.61.5055(14) if the person is on probation for a DUI offense. These types of probation violations can include a 30-day period of confinement and additional license suspensions. Accordingly, an interlock violation charge should always be taken seriously as there are many different ramifications that can stem from a conviction.
