Interlock Devices and DUI

Client Review

John did a very good job. Although the outcome was not 100% what we expected(strange judgement) it was overall positive. I would, have and will continue to recommended him. Although I certainly hope to not need his services again in the capacity I hired him for I would not hesitate to call if I do. Thanks John

The punishment for misdemeanor DUI depends on a number of factors, including: whether your case is filed in municipal court or state court; your criminal record, if any, outside the existing DUI charge, and your conduct during the DUI arrest.
