Following a DUI arrest your license will be suspended for a period of time automatically. Below is a chart from the Secretary of State outlining their procedures. Contacting a lawyer sooner rather than later can help not only to challenge the suspension, but to also help you get a driving permit allowing you to return your life to some degree of normalcy.
