The Implementation of Alcohol Interlocks for Offenders: A Roadmap

Alcohol ignition interlocks are a proven tool to effectively monitor impaired driving offenders and reduce recidivism. Today, all states have passed interlock legislation and are in varying stages of program implementation. In recognition of the challenges that program administrators face in developing and increasing interlock installations, funded the creation of a practical step-by-step roadmap that outlines how to effectively implement interlock legislation and build upon existing program frameworks.

The Roadmap was designed to help administrators and staff plan, develop, and implement improvements to alcohol interlock strategies to ensure that the goals and objectives of legislation are achieved.

It contains practical steps to guide the implementation of alcohol interlock devices as part of a strategy targeting either repeat, high BAC, or first offenders. Important considerations and caveats that impact decision-making at each stage of the process are also highlighted.

The Roadmap was created by the Traffic Injury Research Foundation (TIRF) with input from seasoned professionals who have played a leadership role in these initiatives or who have been intimately involved in interlock delivery. Input was sought from representatives of driver licensing, criminal justice, and hybrid (licensing and justice combined) interlock initiatives to achieve a balanced and inclusive perspective on effective strategies to apply these tools to supervise drunk drivers.
