What is an Ignition Interlock?
An IID is a device wired to a vehicle’s ignition that requires a breath sample from the driver before the engine will start. If the device detects alcohol on the breath, the engine will not start. As the individual drives, the device will request periodic breath samples to ensure continued absence of alcohol in the driver’s system.
How do I know if I need an Ignition Interlock?
The DMV automatically mails an Order of Suspension or Revocation notice along with a DUI IID Insert or an Order of Installment of an Ignition Interlock Device when the department receives notification of a conviction for a DUI violation under California Vehicle Code (CVC) §§23152 or 23153 or Penal Code (PC) §191.5(b) which occurred in one of the pilot counties on or after July 1, 2010. The notice provides you with information about the IID pilot program and driver license reinstatement requirements.
