Ignition Interlock Devices in Rhode Island

When is an IID Authorized?

Rhode Island has authorized the use of ignition interlock devices (IIDs) for certain drivers convicted of alcohol related driving offenses.

When are IIDs Authorized?

As of 2015, IIDs are authorized for:

  • DUI offenders with a BAC of 0.15% or above,
  • repeat DUI offenders and
  • offenders who repeatedly refuse BAC tests

Third or subsequent offenders may be required to use these devices for two years. Requirements begin following the completion of any incarceration period.

What’s an IID?

An IID connects to the vehicle dashboard and the driver breaths into the device prior to starting the vehicle. If the IID detects a BAC above the limit programmed for the device (typically calibrated at .02%), then the engine won’t start. Read more about ignition interlock devices (IIDs).

Where Can I Find an IID Provider?

IID providers are approved for installation throughout Rhode Island. You can find a list of approved IID providers at the Rhode Island DMV website.

Who Pays For it?

In almost all cases the driver who has been convicted of a DUI/DWI pays for the installation and lease of the ignition interlock system. You can expect to pay up to $100 for installation (although some companies offer free installation) and between $75-$120 per month for the lease. This is a rough estimate and your price may be higher or lower depending on your location.
