TIRF USA Annual Ignition Interlock Study: United States

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.
