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 Illinois, alternative sentences are legal options that judges can use to divert individuals from 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. Suspended sentences allow the court to delay serving time under certain conditions. Community service is another alternative that can be ordered, requiring the offender to perform work for the benefit of the community. Diversion programs are tailored to rehabilitate offenders, often focusing on drug and alcohol treatment, education, and prevention. 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 further incidents. Educational programs may also be mandated, aiming to teach offenders about the consequences of crime and to encourage lawful behavior. These alternative sentences are typically considered for non-violent offenders, first-time offenders, or those for whom the judge believes incarceration may not be the most effective form of punishment.
