What is Aggravated DUI in Illinois?

In Illinois, a standard DUI (Driving Under the Influence) charge becomes an Aggravated DUI when specific aggravating factors are present. Aggravated DUI is classified as a felony offense, which means the penalties are significantly more severe than those for a misdemeanor DUI.

Common Aggravating Factors in an Illinois Aggravated DUI

  • Third or subsequent DUI offense (Class 2 felony, punishable by 3 to 7 years in prison)
  • DUI resulting in great bodily harm, disfigurement, or permanent disability (Class 4 felony, 1 to 12 years in prison)
  • DUI resulting in a fatality (DUI manslaughter) (Class 2 felony, 3 to 14 years in prison per victim)
  • DUI while driving on a suspended or revoked license
  • DUI while transporting a child under the age of 16, especially if the child is injured
  • DUI while driving a school bus with passengers on board
  • DUI in a school zone with injuries involved
  • DUI while operating a vehicle without valid insurance or a valid driver’s license

An Aggravated DUI conviction can have devastating consequences on your life, affecting your employment, reputation, financial stability, and personal relationships. This is why you need a skilled DUI defense attorney like James Dimeas to aggressively challenge the prosecution’s case.

How James Dimeas Can Defend Your Aggravated DUI Charge

With over three decades of experience, James Dimeas knows how to craft a strong DUI defense strategy. He thoroughly examines every detail of your case to identify weaknesses in the prosecution’s argument and to challenge any violations of your constitutional rights. Some possible defense strategies for Aggravated DUI include:

1. Challenging the Traffic Stop

If law enforcement did not have probable cause or a valid reason to stop your vehicle, any evidence obtained after the stop could be suppressed and deemed inadmissible in court.

2. Questioning the Field Sobriety Tests

Field sobriety tests are not always reliable and can be subject to errors due to factors such as medical conditions, uneven pavement, poor lighting, or improper instructions given by the officer.

3. Challenging Breath and Blood Tests

Breathalyzers and blood tests must be properly administered and maintained. If there were errors in calibration, improper handling, or chain-of-custody issues, your BAC (Blood Alcohol Concentration) results could be thrown out of court.

4. Proving Lack of Impairment

The prosecution must prove beyond a reasonable doubt that you were intoxicated at the time of driving. If we can show that your driving behavior was not indicative of impairment, it can weaken the state’s case against you.

5. Negotiating for a Reduced Charge or Alternative Sentencing

Even if the evidence against you is strong, James Dimeas is a skilled negotiator who may be able to get your charge reduced to a lesser offense or help you avoid jail time through probation, community service, or alcohol treatment programs.

I got into an argument with my ex-boyfriend. One thing led to another and when he came close to me I pushed him away.

Had a DUI and hired a lawyer who lived in my building that I knew for years and trusted. Thought he was my friend.

I am so lucky to have stumbled upon this great attorney. I made a really stupid mistake at the worst time. I needed to get a case dismissed within 2 or 3 weeks so I could join the military.
