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 South Carolina, 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 (Driving Under the Influence) or DWI (Driving While Intoxicated) 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 South Carolina have the discretion to order the use of SCRAM devices for individuals awaiting trial on bond or as part of a probationary sentence. Additionally, defendants may voluntarily agree to wear a SCRAM device as part of a plea bargain or to demonstrate sobriety, which could potentially influence sentencing decisions. The use of SCRAM devices is governed by state statutes and regulations that outline the legal framework for monitoring and compliance within the criminal justice system.
