The Traffic Injury Research Foundation USA, Inc. (TIRF USA) in partnership with the Association of Ignition Interlock Program Administrators (AIIPA), and TIRF Canada released 2018 Ignition Interlock Installations: State Data. This study is based on 2018 interlock installation data collected from state agencies in the US. It provides a benchmark for state ignition interlock program administrators and impaired driving stakeholders to measure interlock usage and growth in interlock programs. These data provide a comprehensive picture of interlock installations across the United States and are a useful benchmark for state ignition interlock program administrators and the impaired driving community to measure interlock program participation. State data show significant growth in the installation of interlocks, including a 20% increase in new ignition interlocks installed in 2018 compared to 2016. Even though consistent progress has been made increasing installations in the past decade, there is plenty of room for growth using strong strategies to ensure offenders required to install a device do so.
