Criminal DUI Defense in Chicago That Starts Before Court

If you need criminal DUI defense in Chicago, the decisions made in the first 24 to 48 hours after an arrest often shape how the entire case develops. Cook County processes DUI cases through multiple municipal districts and the main criminal courthouse at 26th and California — each with its own judges, prosecutors, and procedural rhythms that an experienced defense attorney recognizes and works within. A charge filed downtown at the Daley Center operates differently than one assigned to the sixth municipal district in Markham, and the approach your attorney takes needs to reflect that.

Herzberg Law Firm focuses exclusively on DUI defense, which means every motion filed, every hearing attended, and every piece of evidence reviewed is informed by a practice built entirely around these cases. Illinois criminal DUI law creates two parallel tracks — the administrative suspension of your license and the criminal charge itself — and addressing both simultaneously from the start prevents gaps in your defense that can compound later.

Chicago clients facing criminal DUI charges typically have more at stake than a fine and court date: commercial driving privileges, professional licenses, CDL status, and immigration standing can all turn on how a DUI case resolves. Discuss your situation early so a defense strategy can be built around what matters most to you.

Criminal DUI defense in Chicago involves evaluating the traffic stop itself, the field sobriety testing sequence, and the chemical testing process — all under Illinois constitutional standards that require each step to have been conducted properly. A breath test result of .08 or higher creates a presumption, but presumptions can be challenged when calibration records are incomplete, when the officer deviated from standardized NHTSA protocols, or when the initial traffic stop lacked reasonable articulable suspicion.

• Traffic stop validity analysis — whether the officer had sufficient legal basis to initiate the stop
• Field sobriety test administration review — conditions, instructions given, and scoring documentation
• Breathalyzer or blood test chain-of-custody and calibration record examination
• Body-worn camera footage requests and evidence preservation before recordings are overwritten
• Coordination of the criminal defense with any pending statutory summary suspension petition

Chicago clients who address both the criminal charge and the license suspension simultaneously avoid the common outcome of winning on one track while losing driving privileges on the other. Schedule a consultation to discuss how criminal DUI defense in Chicago applies to the specific facts of your case.

Choosing criminal DUI defense representation in Chicago means evaluating whether the attorney handles DUI cases regularly enough to know which arguments carry weight in Cook County courtrooms and which ones don't. A practice focused solely on DUI defense brings a different level of familiarity with local court procedures, prosecutorial tendencies, and the technical evidence that determines case outcomes — breathalyzer science, field sobriety research, and the constitutional standards Illinois courts apply.

• Does the attorney practice DUI defense exclusively, or is it one of many unrelated areas?
• Are they familiar with the specific courthouse and district where your case is assigned?
• Can they evaluate breathalyzer calibration records and field sobriety scoring documentation?
• Will they handle both the criminal charge and the license suspension petition together?
• Have they litigated contested DUI bench trials and suppression hearings in Cook County?
