Rid Roads of Impaired Drivers

From the preface of this Traffic Injury Research Foundation publication:

For many years, it has been acknowledged that ignition interlocks are inconsistently applied to
impaired driving offenders, despite compelling research that these devices are effective in reducing
recidivism from 50-90% (Voas and Marques 2003). More recently, this has lead many agencies,
policymakers, practitioners, and researchers, to examine interlock delivery mechanisms in an effort to
gain better understanding of where loopholes exist in the system and, more importantly, what steps
are needed to overcome these problems and improve implementation.
