Shock probation acts as a split sentence of jail time and probation. You will be required to report to jail on the date-time as sentenced by the judge.
Probation supervision involves regular contact with a probation officer, drug/alcohol testing, compliance with all laws, home visits and searches, time on an ignition interlock device, no ownership of guns or dangerous weapons, staying in the county where you reside unless granted permission to leave, and possible continued alcohol and substance abuse treatment. Probation is a tough program, but it is the only way to minimize jail time. If you are on your best behavior throughout your sentence, your probation officer could petition the Court to release you from your sentence early. However, should you violate the terms of your probation you could be sentenced to insert max time in prison.
Bear in mind that Probation will control how and when you get your license back. They will also control the installation and monitoring of the ignition interlock device in any vehicle you either own or operate.
