If you are convicted of a DUI, the consequences will vary depending on the severity of the offense and your state's laws. However, you can expect to face some combination of the following penalties:
Jail time: This is typically reserved for more serious offenses, or if you have multiple DUIs on your record. The amount of time you'll spend in jail will depend on the specifics of your case, but it could be anywhere from a few days to several months.
Probation: You may be placed on probation for a period of time, during which you'll be required to adhere to certain conditions set by the court. These conditions may include things like attending Alcoholics Anonymous meetings, completing an alcohol education program, and/or submit to regular breathalyzer tests. If you violate any of the terms of your probation, you could be sent to jail.
Community service: You may be required to perform community service as part of your sentence. The number of hours will again depend on the details of your case, but it could be anywhere from 20 hours to hundreds.
Fines and fees: In addition to any other penalties imposed by the court, you'll also likely have to pay various fines and fees related to your DUI conviction. These can range from a few hundred dollars to several thousand, depending on the circumstances.
