A person is guilty of Aggravated Driving if convicted of driving under the influence with a BAC greater than 0.15. Such a conviction, or a refusal to take a chemical test, requires ignition interlock use for a minimum of 30 days.
After a period of license revocation, as a condition of modification, the driver must agree, except in certain circumstances, to only operate motor vehicles that are equipped with an ignition interlock device. The motor vehicles department will issue a new driver’s license with the words “Interlock Required” on it.
For a first time offender, with a BAC greater than 0.15, or chemical test refusal, once their initial license revocation period is finished, they will be required to have an ignition interlock device for 1.5 years, or until their driving privileges would normally be reinstated, whichever is longer. For a second time offender, the interlock period is 4 years, or until driving privileges are to be reinstated, whichever is longer.
For a third or subsequent offense, the period is 5 years or until their license would be normally reinstated, whichever is longer.
Exemptions: Employer.
