What is an 'ignition interlock device' or IDD?

Neil Shouse (Defense Attorney) gives expert video advice on: What is an 'ignition interlock device' or IDD?; Can my vehicle be impounded if I get a DUI?; What do the police do with my vehicle if I am arrested for a DUI?

An 'ignition interlock device' or IDD is a small breathalyzer that is attached to the ignition in your car that you have to blow into before you start your car. And if you blow into it and it detects the presence of alcohol then your car will not start. It is a precautionary measure imposed by the courts to prevent people who are convicted in DUI from repeating the offence. And often times if your BEC is particularly high, or if it is a second, or third, or multiple offence, then the court will require you as a condition of probation to have the IDD or Ignition Interlock Device installed in your car.
