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 Delaware, the use of an alcohol ankle monitor, or SCRAM (Secure Continuous Remote Alcohol Monitor), can be a condition imposed by the court for individuals awaiting trial or as part of a sentence for those convicted of DUI/DWI offenses. The device is designed to monitor the wearer's alcohol consumption through skin perspiration and is tamper-resistant to ensure compliance. If a person tries to remove or tamper with the SCRAM, it will be detected and reported. Judges in Delaware may require the use of a SCRAM for individuals on bond awaiting DUI/DWI trials or as a condition of probation after conviction. Additionally, individuals convicted of DUI/DWI may choose to wear a SCRAM voluntarily as a demonstration of sobriety and potentially to mitigate the severity of their sentence. The specific conditions and duration of SCRAM usage are determined by the court on a case-by-case basis, taking into account the circumstances of the offense and the offender's history.
