An ignition interlock device (IID) keeps a vehicle from being driven by someone who has been drinking. After any DUI or Refusal conviction, Alaska requires one on every vehicle you drive, and the time grows with each conviction.

Know the rule

When convicted of a DUI or Refusal, you must use an ignition interlock device on any vehicle you operate (AS 28.35.030(b) and/or AS 28.35.032(g)).
