How an Illinois DUI Lawyer Can Help You

A DUI arrest in Illinois is enough to change the trajectory of your life. The penalties are expensive, and you can even get prison time for driving under the influence (DUI). Getting arrested for drunk driving is enough to get you a criminal record, especially if you don’t have a good defense.

Have you ever been charged with driving under the influence? The state of Illinois takes DUI charges seriously, and the laws can be very complex. You may need an experienced DUI defense attorney to help you fight the DUI charges. At Hirsch Law Group, we have a team of experienced DUI attorneys who are dedicated to providing top-notch legal representation for individuals facing DUI charges in Illinois.

How Can I Fight a DUI in Illinois?

In Illinois, you have the right to challenge every piece of evidence brought against you. At Hirsch Law Group, we treat a DUI arrest as the beginning of a strategic defense, not the end of your case. Fighting a DUI requires a deep understanding of police procedure and forensic science. We look for “holes” in the prosecution’s case to have your charges reduced or dismissed entirely.

Proven Strategies for Challenging DUI Charges

There Challenging the Stop: Officers need “reasonable suspicion” to pull you over, not just a hunch. If the stop was illegal, any evidence found afterward can be thrown out.

Field Sobriety Tests: These are subjective and prone to error. Factors like bad lighting, medical issues, or nerves can cause a “fail,” even if you’re sober.

Breath & Blood Results: Equipment must be perfectly maintained and calibrated. We also check for “Rising BAC”—where your levels were legal while driving but rose by the time you were tested.

Saving Your License: In Illinois, licenses are suspended 46 days after an arrest. We can file a petition to fight this, helping you keep your driving privileges during your case.

What is Considered a DUI or DWI in Illinois?

DUIs or DWIs are not just restricted to driving under the influence of alcohol. It also includes driving under the influence of cocaine or other illegal drugs and controlled substances. When a police officer pulls you over for a suspected DUI, you will likely be asked to exit the vehicle and perform a breath test.
