After an Arizona DUI conviction, drivers must often install an ignition interlock device on their vehicle before having their driving privileges reinstated. An ignition interlock is a small device installed near the steering column that requires a driver to blow into a tube before starting their vehicle. If there is any alcohol on the driver’s breath, the car will not start. Ignition interlock devices are designed to prevent those with a DUI conviction from getting behind the wheel after having anything to drink. In Arizona, for those required to install an interlock device on their vehicle, it is a crime to drive a vehicle without one.
Earlier this month, a state appellate court issued an opinion in an Arizona DUI case involving the question of whether the prosecution must prove that the defendant knew he was required to install an ignition interlock device of his vehicle. Ultimately, the court concluded that the prosecution must present proof that the defendant “knew or should have known an ignition-interlock restriction was in effect at the time of the offense.” Thus, the court vacated the defendant’s conviction.
The Facts of the Case
According to the court’s opinion, in 2015, the defendant was convicted of a misdemeanor DUI offense. As a part of the defendant’s sentence, he was required to install an ignition interlock device on any vehicle he drove once his license was reinstated. Initially, the defendant complied with the requirement. The Department of Transportation, Motor Vehicle Division (MVD), told the defendant that he could remove the device on June 1, 2017.
