Ignition Interlock

Ignition Interlock Program (IIP)

The Ignition Interlock Program (IIP) is primarily for individuals convicted of a drinking-and-driving offense. While it was previously used for certain repeat or aggravated DWI offenders, it has become more widely implemented and publicized across New York State due to Leandra’s Law legislation.

Leandra’s Law, which applies to anyone convicted of a drinking-and-driving offense on or after August 15, 2010, requires individuals convicted of DWI—whether misdemeanor or felony—to install an Ignition Interlock system on any vehicle they own or operate. The system requires the operator to provide a breath sample before the vehicle engine will engage. Additionally, random “rolling” samples may be required, and the system records real-time GPS data and a photograph of the individual providing the sample.

In Madison County, offenders sentenced to probation supervision are mandated by the Court to install an Ignition Interlock device. The Probation Department supervises their Ignition Interlock conditions.

Offenders sentenced to a conditional discharge are also required to install Ignition Interlock devices. Their conditions are supervised by the Madison County District Attorney’s Office.
