Here are the things a DUI defense attorney can do:

Keep track of legal deadlines: A DUI attorney can keep a track of the deadlines and fill out the necessary paperwork and documents within the protocols and procedures set by the court.

Negotiate with the prosecutor: Your attorney may work with the prosecutor to negotiate a plea bargain. A plea bargain can have your case dismissed entirely or the charges reduced.

Find loopholes and errors: An attorney with experience in DUI cases can spot inconsistencies or procedural loopholes in your case and work toward having the case dismissed.

Expunge your conviction: If you are convicted, your attorney can help you get the conviction expunged so that it does not affect your credit or future employment. It is important to note that expungement procedures may differ per state and local jurisdictions. Only an experienced attorney will know how to navigate the system.

Get a fair judgement: Once convicted, you are likely to face serious punishment. If you have a DUI defense attorney representing you, he or she can negotiate a fairer judgment from the court, such as community service.
