The Traffic Injury Research Foundation USA, Inc. (TIRF USA), in partnership with the Association of Ignition Interlock Program Administrators (AIIPA) and TIRF in Canada, conducted a national survey of the number of total installed and active installed ignition interlocks as well as installation rates of interlocks among eligible offenders in the United States in 2016 and 2017. These data provide a comprehensive picture of interlock installations across the country and comparisons are made to data from previous years to describe trends. These survey data, collected since 2014, demonstrate a steady growth of interlock installations in the United States, but also indicate that further growth is still possible and necessary.
