An alcohol ankle monitor—also known as a SCRAM (Secure Continuous Remote Alcohol Monitor)—is an ankle bracelet consisting of two small boxes secured by a strap and worn 24 hours a day. A SCRAM monitors perspiration on the skin for alcohol content—similar to the way a breathalyzer test measures blood alcohol concentration. A SCRAM is tamper-resistant and if a person attempts to remove or tamper with it, the tampering will be detected and reported through the remote monitoring service.

A person who is out of jail on bond awaiting a DUI/DWI trial may be ordered to wear a SCRAM. And a person who has been convicted of a DUI/DWI criminal offense may be ordered to wear a SCRAM for some period of time—as a condition of probation, for example. A person convicted of a DUI/DWI criminal offense may also volunteer to wear a SCRAM in an effort to reduce the severity of the sentence.

In Arizona, a SCRAM (Secure Continuous Remote Alcohol Monitor) device may be used as a condition of bond or probation for individuals charged with or convicted of DUI/DWI offenses. The device is designed to monitor an individual's alcohol consumption by measuring the perspiration on their skin and is worn around the ankle. It is tamper-resistant and any attempts to remove or interfere with the SCRAM are reported to the authorities. Judges in Arizona have the discretion to order the use of a SCRAM device either pre-trial or as part of a sentencing condition for DUI/DWI offenders. This can be mandated to ensure that the individual abstains from alcohol consumption. In some cases, wearing a SCRAM voluntarily may be seen as a proactive measure by the defendant to demonstrate sobriety and responsibility, potentially influencing the court's sentencing decision. The specific regulations and application of SCRAM devices may vary by jurisdiction within the state, and the use of such monitoring is subject to the approval of the court handling the DUI/DWI case.
