The average DUI case in California will take around four to six months from start to finish. However, there are a number of factors that can influence the length of time it takes for a case to be resolved. These include the severity of the offense, the jurisdiction in which the offense occurred, and whether the defendant is represented by an attorney.

In general, misdemeanor DUI cases are resolved more quickly than felony DUI cases. This is because felonies are typically more serious offenses that require more investigation and may go to trial. Misdemeanor cases, on the other hand, are usually handled through plea bargaining and do not require as much time for discovery and trial preparation.

The jurisdiction in which a DUI offense occurs can also affect the length of time it takes for a case to be resolved. For example, cases in rural areas may take longer to resolve than cases in urban areas. This is because rural courts tend to have fewer resources and staff than urban courts. As a result, cases in rural areas often take longer to move through the system.

Finally, whether or not a defendant is represented by an attorney can also influence the length of time it takes for a case to be resolved. Defendants who are represented by an attorney often have their cases resolved more quickly than those who represent themselves. This is because attorneys are familiar with the court system and know how to navigate it efficiently.
