All holders of a Vermont Ignition Interlock Restricted License (RDL) or Ignition Interlock Certificate (IIC) must have a camera-equipped ignition interlock device installed in the vehicle. When contacting an installer (or the manufacturer), you must inform them that Vermont requires a camera-equipped device. If you do not have a camera-equipped device, you will not be allowed to drive the vehicle until a camera-equipped device is installed.
An Ignition Interlock Device Restricted License (RDL) allows you to drive non-commercial vehicles equipped with an ignition interlock device (IID), 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.
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 onboard 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.
