It is difficult to predict how long your DWI case will take and it can often depend on the location of the offense, whether there was an accident or injuries that resulted, and whether you have a prior record. In some instances, a DWI charge can be resolved at the first court appearance and in other cases it can take a year or longer to resolve a DWI case. You should talk to your DWI attorney about your particular case to get a better understanding of how long your case may take. Some counties have DWI policies with respect to the resolution of DWI cases which can add time to the process.
