What is an Ignition Interlock Device

An Ignition Interlock Device, referred to as an “IID”, is an after-market device which is installed in a vehicle.  The IID is connected to the starter or ignition, or other on-board computer system of a vehicle.  The device prevents a driver from operating the vehicle if the driver has been drinking.  Before starting the vehicle, a driver must blow into the device; if the driver’s BAC is at or over a pre-set limit, 0.02 in Vermont, the IID will not allow the vehicle to start.  Once the vehicle is started, at random times during the operation of the vehicle, the device will prompt the driver

What is an Ignition Interlock Device Restricted Driver’s License?

An Ignition Interlock Device Restricted License, referred to as an “RDL”, allows you to drive  non-commercial vehicles equipped with an ignition interlock device, while your Vermont license is suspended or revoked for an alcohol-related driving under the influence offense.  You are granted a conditional reinstatement ahead of your normal eligibility date if you participate in the Ignition Interlock Program
