Will I be required to install an ignition interlock device?

 

A:

Whether you will be required to install an IDD in your vehicle depends on a few factors. The first is the state you live in. Judges in most, though not all, states have the option of requiring an IDD.

The second is whether you have prior DUI convictions. In many states, IDDs are usually reserved for multiple offenders. If you have prior DUIs, it is more likely that an IDD will be part of your probation. However, some states require IDDs for all offenders, regardless of their criminal record.

The third is the specific circumstances of your arrest. Aggravating factors such as an excessively high BAC, injury to other drivers, or a refusal to submit to a chemical test at the police station can increase the likelihood that a judge will require you to have an IDD installed in your vehicle.
