If you are convicted at trial, or if you reach a plea bargain agreement with the State of Texas for community supervision (probation) in a DWI case, then prepare for quite a bit of additional expense in the upcoming future.
Standard provisions of DWI
probation are: DWI Education Course, Victims Impact Panel Class, Substance Abuse Evaluation (and any conditions that are determined necessary), many hours of community service, no alcohol consumed during the period of probation, and several other conditions under the Code of Criminal Procedure.
If you have a blood alcohol concentration (BAC) over a .15, then the court will require you to have a deep lung device installed on any vehicle you operate for at least 1/2 of the period of probation.
In short, you do not want to be convicted.
