Former State's Attorney With Over 35 Years of Experience

Felony DUI

The law has little patience with repeat DUI offenders. One convicted of aggravated DUI faces serious consequences including a prison sentence. It is important to understand, however, that if you have been arrested for felony driving under the influence then you have options. An attorney may be able to help you fight the charges. Our Chicago felony DUI lawyer handles such matters. Contact our Orland Park office today to schedule an initial consultation.

Charges for aggravated or felony DUI begin with the prosecution holding a preliminary hearing or seeking an indictment from the grand jury. If the defendant is out of custody then the matter will proceed to trial within 180 days. If the defendant is in custody then trial will take place within 120 days. These speedy trial rights may be waived. Common defenses in DUI cases revolve around whether police illegally stopped the vehicle, whether the collection of blood evidence was faulty, and whether testing equipment was not properly calibrated. It is crucial that you retain a lawyer to assist you with these issues.
