Driving under the influence of alcohol, also known as "DUI" or "drunk driving", is an offense that is clogging American courts. Yet, DUI can be a difficult charge to defend, given the degree of science and law involved and difficulties with proving or disproving evidence. In the past few years, the entire legal structure of DUI has changed due to public outcry over the lost lives of innocent victims. Today, if you drink and drive, keep the phone number of an experienced DUI law firm in your back pocket. You may find yourself going to jail, losing your license, paying heavy fines and court costs, and facing humiliation from your peers.
