Using two sites located in different states, the study represented
a substantial and comprehensive effort to document and explain the driving
patterns of a representative sample of first-time alcohol-impaired driving
offenders. The research effort encompassed an observational study of
alcohol-impaired driving offenders and focus group research. Subjects
were persons who had recently lost their license as a result of a first-time
alcohol-impaired driving conviction.
In a unique approach to gather unobtrusive and unbiased observational
data, the observational study was conducted in association with Pinkerton
Investigation Services, Inc. Trained and bonded surveillance professionals
observed drivers during their license suspension
and if their license was reinstated, again after the suspension ended.
For both the during-suspension and post-suspension periods, drivers
were observed for four hours on a weekday morning and for four hours
on a Friday or Saturday evening. The comparison of travel during and
after the suspension period permitted inferences to be drawn concerning
whether an offender's travel patterns changed as a result of the suspension.
To supplement the observational data, focus groups of alcohol-impaired
driving offenders at each site provided information on the transportation
patterns of offenders before, during, and after suspension and their
motivations for violating or complying with the license suspension.
