Probation after a DUI conviction involves strict supervision and adherence to certain conditions. These conditions may include mandatory alcohol and drug testing, attending counseling or treatment programs, and regular meetings with a probation officer. The length of probation can vary, but it typically lasts between one to three years. Violating the terms of probation can result in additional penalties, such as fines, license suspension, or even jail time. It is important to comply with all probation requirements to successfully complete the program and avoid further legal consequences.
