interlock devices have long been used as a means of reducing recidivism
for persons with impaired driving offenses. They've been used in Colorado since 2001. While Colorado does not require a mandatory ignition interlock for all DUI offenders, they will almost certainly be required in cases where:
*the BAC is considered high (.15 or higher) *the person has more than one DUI or DWAI *the blood or breath test is refused
In addition, ignition interlocks can be voluntarily installed in oder to reinstate driving privileges early (in many cases), and
Their use can be extended in cases where a person has multiple attempts to drive under the influence of alcohol with an installed ignition interlock.
IGNITION INTERLOCK EDUCATION & TREATMENT
In an article from 2011,
the American Journal of Preventive Medicine concluded that “methods for
combining interlock programs with alcohol treatment programs should be
explored further as a potential means of extending the effectiveness of
interlock beyond the period during which they are installed”.
