Summary
Florida's Administrative Reinstatement Interlock Program (ARIP) mandates ignition interlocks for DUI offenders seeking license reinstatement. While effective in reducing recidivism for those who install them, many offenders do not qualify for reinstatement.
Area of Science:
- Traffic safety research
- Criminal justice policy
- Behavioral science
Background:
- Ignition interlocks significantly reduce driving-under-the-influence (DUI) recidivism by 64%.
- Offenders often resist interlock installation, risking driving with revoked licenses.
- Florida's Administrative Reinstatement Interlock Program (ARIP) mandates interlocks for license reinstatement.
Purpose of the Study:
- To evaluate the effectiveness of Florida's ARIP implemented in 2002.
- To analyze offender behavior and recidivism within the ARIP over a 10-year period.
Main Methods:
- Analysis of driver and interlock program records for 120,000 DUI offenders over 10 years.
- Description of the sanction system flow: conviction, reinstatement, interlock program, and post-interlock.
- Logistic regression and survival analysis to identify characteristics and evaluate recidivism.
Main Results:
- One-third of convicted offenders were in license revocation periods at any given time.
- Half of offenders completing revocation periods did not meet reinstatement requirements.
- ARIP offenders who installed interlocks showed reduced recidivism during device use.
Conclusions:
- After 10 years, Florida's ARIP successfully mandates interlock installation for at least six months for eligible offenders.
- A significant portion (50%) of offenders completing revocation periods do not, or cannot, qualify for license reinstatement.
