How long you have to wear an ankle bracelet depends almost entirely on why a court ordered it. Most people wear one for somewhere between 30 days and two years, but the range runs from a couple of weeks for a minor alcohol case to lifetime monitoring for certain sex offenses. Federal probation alone can last up to five years for a felony or a misdemeanor.1Office of the Law Revision Counsel. 18 USC 3561 – Sentence of Probation The exact number in your case is set by the court order or plea agreement that put the device on, and it tracks the legal reason for the monitoring.
How Long Monitoring Lasts by Case Type
Pretrial Release
If a judge ordered the monitor as a condition of release before trial, you wear it until the case ends — by plea, dismissal, or verdict. There is no statutory cap on how long pretrial monitoring can run; it ends when the case does. In practice that often means several months to more than a year, because criminal cases move slowly. For certain federal sex offenses against minors, electronic monitoring is a mandatory minimum condition of pretrial release.2Office of the Law Revision Counsel. 18 USC 3142 – Release or Detention of a Defendant Pending Trial
Probation
When monitoring is a probation condition, it follows the probation term, but not always for the full length. Federal probation runs one to five years for a felony, up to five years for a misdemeanor, and up to one year for an infraction.1Office of the Law Revision Counsel. 18 USC 3561 – Sentence of Probation State probation terms vary and can run longer for serious offenses. A judge might order the monitor for only the first several months of probation, or a probation officer might recommend removing it after a period of consistent compliance.
Home Confinement
Home confinement sentences typically run from 30 days to two years or more. In the federal system, electronic monitoring for home confinement can only be imposed as an alternative to incarceration, not added on top of it.3United States Courts.

Parole and Supervised Release
After prison, monitoring under parole or federal supervised release typically runs six months to several years. Federal supervised release cannot be terminated early until you have completed at least one year, no matter how clean your record.4Office of the Law Revision Counsel. 18 USC 3583 – Inclusion of a Term of Supervised Release After Imprisonment
Alcohol Monitoring in DUI Cases
For DUI and other alcohol-related offenses, courts often order a SCRAM bracelet that tests for alcohol through the skin. The most common requirement is 90 consecutive clean days, but sentences have ranged from as short as two weeks for minor offenses to as long as ten years in cases involving a death. The monitor comes off when you complete the ordered period without any drinking or tampering event — miss a day and the clock often restarts.
Sex Offense Monitoring
Sex offense cases sit at the far end of the spectrum. Several states require GPS monitoring for convicted sex offenders, and at least seven have enacted lifetime monitoring for certain offenses.5United States Courts. The Challenges of GPS and Sex Offender Management In those cases the monitor is a registration condition, not tied to any probation or parole term, and it continues indefinitely.
What Can Shorten or Extend the Time
The seriousness of the underlying offense drives the starting number. A misdemeanor DUI might mean a few months of alcohol monitoring; a felony domestic violence conviction with a protective order could mean years of GPS tracking. Read the court order or plea agreement carefully. Some set a firm end date. Others tie monitoring to the length of supervision with no specific removal date.
Your behavior on the device moves the number in both directions. Consistent compliance — appointments kept, curfew observed, approved zones respected, battery charged — builds the record that supports early removal. Violations do the opposite. Entering an exclusion zone, tampering with the strap, or letting the battery die can trigger a non-compliance report, which may extend monitoring, tighten restrictions, or lead to revocation of release altogether.
Supervising officers also weigh risk factors: criminal history, community ties, employment stability, and the nature of the offense. Completing court-ordered treatment, counseling, or educational programs helps show reduced risk and supports a shorter monitoring period.
Who Decides When It Comes Off
The judge holds the most power. Judges set the initial terms and make the final call on any request to modify or end monitoring, even when a probation officer supports removal.
Probation and pretrial services officers work within the judge’s parameters but have real day-to-day discretion. The supervising officer chooses the monitoring technology, sets curfew hours, and decides whether a lapse becomes a warning or a formal non-compliance report. When a removal request reaches the judge, the officer’s recommendation carries significant weight.3United States Courts. Overview of Probation and Supervised Release Conditions – Chapter 3: Location Monitoring
For people released from state prison, parole boards decide whether an ankle monitor is required and for how long. In the federal system, supervised release terms are set by the sentencing judge, not a parole board.
How to Ask for Early Removal
You are not locked into the full term if your circumstances support cutting it short. The general path is the same across pretrial release, probation, and supervised release: your attorney files a motion to modify conditions, and the judge decides.
For federal probation, a court can terminate supervision early at any time for a misdemeanor or infraction. For a felony, you must first complete at least one year of probation. Early termination requires that your conduct warrant it and that the change serve the interest of justice.6Office of the Law Revision Counsel. 18 USC 3564 – Running of a Term of Probation The same one-year minimum applies to early termination of federal supervised release.4Office of the Law Revision Counsel. 18 USC 3583 – Inclusion of a Term of Supervised Release After Imprisonment
Pretrial release has no minimum waiting period, but most judges want to see several months of flawless compliance before they’ll consider removing the monitor. A strong request generally includes a spotless compliance record, proof of stable housing and employment, and a supportive recommendation from the pretrial services officer. If the officer opposes removal, the motion faces a steep uphill climb.
What helps: completed treatment programs, steady employment, strong community ties, and a clean record over a sustained period. What hurts: any history of violations, pending charges in other cases, or a high-risk classification tied to the original offense. Your attorney should raise the request informally with the supervising officer before filing. A motion that surprises the officer rarely goes well.
What Happens When Monitoring Ends
When your monitoring period concludes or a judge grants early removal, you’ll get notice from the supervising officer or the court and report to a scheduled appointment at a probation office or monitoring company facility. A technician removes the device, checks the equipment, and finishes the paperwork.
Removal does not necessarily end your supervision. In many cases you shift to a less restrictive form — regular probation check-ins without electronic monitoring, for example — and remain subject to every other condition of your probation or release that wasn’t separately modified. Skipping the removal appointment or cutting the device off yourself before the authorized date can bring new charges or a violation that extends supervision further.
