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 Oklahoma, 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 will report any attempts at removal or tampering. Judges in Oklahoma have the discretion to order the use of SCRAM devices for individuals awaiting trial on DUI/DWI charges or as part of a sentence or probation conditions following a conviction. The use of a SCRAM may also be voluntarily undertaken by an offender as a demonstration of sobriety and potentially to mitigate sentencing. The specific regulations and application of SCRAM devices may vary by jurisdiction within the state, and the decision to use such monitoring is typically made on a case-by-case basis.
