If you were arrested for a misdemeanor DUI offense, you probably won't have to stay in jail until trial. At your appearance, the judge will likely order you to remain out of custody under your “own responsibility” (OR). As part of this order, the judge will likely order you to “obey all laws.” In Monterey County, it's common for the judge to also order that you don't consume alcohol and that you don't visit places where alcohol is sold. The judge can also add bail (or increase the bail amount) if he gets into more trouble.
If you refuse to submit to a chemical test, you will still be arrested for drunk driving. However, you will also face an “allegation of rejection”. A denial charge carries additional penalties for drunk driving, including a one-year driver's license suspension and two mandatory days in county jail. A myriad of expenses that are normally associated with a drunk driving conviction include bail, the costs of towing or seizing the car, court costs, legal fees, legal fees, DUI education programs, higher insurance premiums, and probation rates.
