Alternative sentences include the sentences or punishments a judge may give, other than a traditional jail or prison term, or the death penalty. Alternative sentences are often given in combinations of fines, restitution, probation, deferred adjudication, suspended sentences, community service, diversion programs, drug and alcohol treatment programs, house arrest, breathalyzer or ignition interlock device (IID) installation, and teaching or attending classes regarding crime and criminal behavior.

In Idaho, alternative sentences are legal options that judges can use to punish offenders without imposing traditional incarceration or the death penalty. These alternatives are designed to address specific circumstances of the offender or the offense and can include fines, restitution to victims, probation, and deferred adjudication where judgment is postponed as the offender complies with certain conditions. Suspended sentences allow the court to delay serving time in jail or prison on the condition that the offender meets certain requirements. Community service is another alternative where offenders contribute to the community as part of their sentence. Diversion programs are designed to redirect offenders, particularly first-time and non-violent individuals, away from the criminal justice system, often with a focus on rehabilitation. Drug and alcohol treatment programs may be mandated for offenders with substance abuse issues. House arrest confines an individual to their home instead of jail. Breathalyzer or ignition interlock device (IID) installation may be required for DUI offenders to prevent them from operating a vehicle while impaired. Educational programs may also be ordered to teach offenders about the consequences of crime and to encourage lawful behavior. These alternative sentencing options are subject to the discretion of the court and the specific laws and guidelines that govern sentencing in Idaho.
