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 Connecticut, 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 issues related to the offense or the offender's needs and may include fines, restitution to victims, probation, and deferred adjudication, where judgment is postponed while the defendant completes certain conditions. Suspended sentences allow the court to delay serving a sentence as long as the defendant complies with certain conditions. Community service is another alternative that can be ordered, requiring the defendant to perform work for the benefit of the community. Diversion programs are tailored to address underlying problems such as substance abuse or mental health issues, and may involve mandatory participation in treatment programs. House arrest confines an individual to their home instead of jail, sometimes monitored by electronic devices. Breathalyzer or ignition interlock devices (IIDs) may be required for those convicted of driving under the influence. Educational programs may also be mandated, where offenders learn about the consequences of crime and strategies for rehabilitation. These alternative sentences aim to rehabilitate offenders, reduce recidivism, and alleviate the burden on the prison system.
