That all depends on whether or not you're a first time offender. I mean if you're a first time offender conceivably you could still go to jail if the judge wants to send you there, but most attorneys know who the judges are and will tell you that that's not likely to happen for a first time offender. Typically you're looking at probation, community service, a hefty fine, and collateral consequences like your insurance rates going up.
However for second and third time offenders, or further than that, yes you are looking at jail time, possibly mandatory jail time. It's important to get an attorney who knows what that judge or what they do in that particular county because there may be ways to avoid jail with things like house arrest, electronic monitoring, and so forth. It's very important in that sense to talk to an attorney if you're a multiple offender.
