In the interest of facilitating the development of better, more effective interlock programs, TIRF has organized a series of symposia on ignition interlock programs. Each symposium has involved an international group of researchers, interlock manufacturers, service providers, policy makers and interlock program specialists. The first symposium involved about 30 participants and was held in Montreal, Canada in September 2000. This meeting resulted in a comprehensive document outlining a series of “best practices” for interlock programs (Beirness 2001). A second, larger symposium was held in Toronto, Canada in November 2001 to discuss the use of ignition interlocks as a mandatory condition of license reinstatement for DWI offenders (Beirness & Simpson 2003).

12th Annual Interlock Symposium
Palm Springs, USA - October 2011

The 12th International Alcohol Interlock Symposium held in Palm Springs, California, was the largest of the symposia to date. More than 175 attendees representing 18 different countries attended the event. The growth of the symposium, which had humble beginnings with only 26 attendees present in 2000,demonstrates the continued interest in not only the use of alcohol interlocks but also in the enhancement of existing interlock programs, the pursuit of technological innovation, and the implementation of new legislation and programs internationally.

11th Annual Interlock Symposium
Montebello, Canada - October 2010

The 11th Annual International Alcohol Interlock Symposium was held in Montebello, Canada in October 2010. The event focused on promoting consistency across jurisdictions regarding strategies to manage alcohol interlocks (harmonizing policy and practice) to reduce duplication, better leverage successes, and minimize the growing conflict stemming from inter-jurisdictional impediments. The agenda included a continued focus on knowledge transfer and program development with the intention of ensuring policy is consistent with practice, and identifying best practices to bring consistency to alcohol interlock programs.

More than 130 attendees representing 17 countries participated, making it one of the largest Symposia to date.

4th Annual Interlock Symposium

Hilton Head Island, South Carolina - October 2003

The theme of this symposium was “Enhancing Acceptance, Participation and Compliance”. At this symposium, participants examined existing legislation in support of interlocks and the diversity of ways in which programs were implemented in order to identify barriers to the success of these programs and ways they could be overcome. Discussion groups following each panel of presentations permitted participants representing researchers, manufacturers and practitioners to explore these concerns, as well as potential solutions, in greater detail. The proceedings of this symposium are now available.

3rd Annual Interlock Symposium

Vero Beach, Florida - October 2002

The theme of the Vero Beach symposium was “Enhancing the Effectiveness of Interlock Programs”. Leading scientists presented the latest research findings on various aspects of interlock programs, including program evaluations, the monitoring of offenders, the use of information from the interlock data recorder, enhancing participation, and the integration of interlocks with alcohol treatment programs. The proceedings of this symposium were published in a special issue of Traffic Injury Prevention as a seperate collection of articles prepared by the scientists who presented the findings of their research at the symposium. The publication of these articles underscores the importance of continued research on various aspects of interlock programs to further their development. The results provide valuable contributions to our understanding of how interlock programs work and offer insights into ways to make such programs more efficient and effective.
