Benefits & Success
Based on the evidence collected, continuous alcohol monitoring is a viable deterrent for offenders. Of 3,707 people placed in the alcohol monitoring program, only 47 participants have had confirmed alcohol readings and only 85 others have been terminated from the program for other violations.
Continuous alcohol monitoring is an effective technology for offenders with alcohol-related crimes. It is used on post-conviction cases that involve driving while intoxicated and driving under revocation and/or suspension. Alcohol monitoring is also used in pretrial cases involving alcohol in domestic violence cases, as well as habitual traffic offenses.
The continuous alcohol monitoring program accepts referrals from the Denver County Court Probation and Denver District Court Probation. The program also works with the Colorado Department of Motor Vehicles. Enforcement hearing officers can refer people with suspended licenses to continuous alcohol monitoring as a condition for driver's license reinstatement.
Currently, alcohol monitoring in our department, uses a device that tests offender alcohol concentration through the skin (trans-dermal alcohol concentration, or TAC). The bracelet is water-resistant and tamper-resistant. The offender is tested at least 24-times per day. If alcohol is detected, the system automatically begins sampling every 20 minutes until alcohol is no longer present. The results are collected throughout the day and stored in the bracelet. The results are uploaded once a day via a modem to the offender's home, or once a week to the office. The results are then analyzed and posted on a secure website, so officers can access the information when needed. If the Defendant attempts to place objects (tape, playing cards, paper, etc…) between the skin and the bracelet to defeat it, the built-in tamper technology will alert the officer.
