Introduction
Currently, 30 states and the District of Columbia have laws requiring all offenders, including first-time offenders, to install an IID. An additional eight states—Florida, Michigan, Minnesota, North Carolina, Pennsylvania, Rhode Island, South Carolina and Wyoming—require high BAC offenders—trigger levels range between .1 and .17—and repeat offenders to install IIDs. Five states—Georgia, Ohio, Massachusetts, Maine and Missouri—require only repeat offenders to install the devices. The remaining seven states—California, Indiana, Nevada, North Dakota, Montana, South Dakota and Wisconsin— do not have any statewide requirements regarding IIDs, but judges have the discretion to order offenders to install one if they consider it necessary.
In December 2013, the National Highway Traffic Safety Administrations released model guidelines for states encouraging them to adopt ignition interlock for first-time convicted drunk drivers and establish a minimum length of time in which offenders must use the interlocks. The report also contains guidelines for program administration and for vendors and service providers.
