One of the penalties defendants may face for Driving Under the Influence (DUI) in Pennsylvania is license suspension. Depending on the number of offenses you have had, your suspension may last between 12 and 18 months. However, defendants may be able to apply for a restricted license to use until this suspension is over. This could mean a world of difference for those who rely on a vehicle to commute to work, see their children, purchase groceries or fulfill other important responsibilities.
