Belleville DUI Lawyer
The Conner Law Firm defends DUI charges in Belleville and St. Clair County, led by former prosecutor Erin K. Conner.
Driving under the influence, be it alcohol, cannabis, or any other intoxicant, is the type of charge that can happen to almost anyone, which means an otherwise law abiding citizen can find themselves involved in the criminal justice system for the first time. An arrest for DUI in Illinois starts two parallel legal battles: criminal prosecution and administrative proceedings to suspend driving privileges. It is critical that the attorney representing you knows the procedures, strict timelines, and methods to challenge the officer’s allegations against you.
The Conner Law Firm defends DUI charges as a core component of our practice and is well versed in the strategies that have traditionally yielded positive results for both the administrative driving revocation proceeding and also criminal prosecution. Having the experience of prosecuting DUI cases, including DUIs involving death and permanent disfigurement, Erin K. Conner knows how successful DUI prosecutions are built, and the methods to employ to dismantle a questionable case at every stage.
Ms. Conner has appeared and defended more than a hundred DUI cases in St. Clair County and other counties throughout southern Illinois. With the Conner Law Firm’s experience on your side, your chance of preserving your career, professional licensure, social standing, and freedom are protected to the utmost extent.
Illinois DUI Laws and Penalties
When facing DUI charges in St. Clair County, understanding the law and how 625 ILCS 5/11-501 governs DUI in Illinois is important. The state has some of the strictest DUI laws in the nation, and penalties escalate based on how many offenses you have as well as any aggravating factors.
What makes Illinois one of the strictest states for DUI punishments is that it has a zero tolerance policy for any driver under 21. Any measurable amount of alcohol detected, even if it is below the 0.08% BAC state legal limit, is considered a violation of Illinois DUI laws. Commercial truck drivers also face harsher scrutiny, where their legal limit is at 0.04% BAC.
DUI First Offense
For most facing a first DUI offense, it is charged as a Class A misdemeanor. The penalties you face could include up to 364 days in jail, $2,500 fine, and a 1-year license revocation, which becomes 2 years if you’re under the age of 21. When your BAC is measured at 0.16% or higher, the statute mandates at least 100 hours of community service be part of any plea or sentence.
DUI Second Offense
A second charge of DUI, absent extraordinary circumstances, is also prosecuted as a Class A misdemeanor, though the courts impose a mandatory minimum of 5 days in jail or 240 hours of community service, with a maximum of 364 days in jail and $2,500 in fines.
DUI Third Offense
If convicted of a third DUI offense, you will face charges of a Class 2 felony. Punishments range from 3 to 7 years in prison, or potentially a period of probation with conditions and fines.
Aggravated DUI also upgrades your charges to a felony when certain aggravating factors are present. If you cause an accident that results in great bodily harm or death, in a school zone, or driving with a passenger under the age of 16, aggravated DUI is issued as a felony. In most cases, it is a Class 4 felony which imposes prison sentences of 1 to 3 years, though depending on the circumstances, a Class 1 felony could be the pending charges, which would have you in prison anywhere from 4 to 15 years. You can learn more by reading the Illinois DUI penalties guide.
The bottom line: DUI charges are serious, and the actions you take today make all the difference for your tomorrow. The Conner Law Firm defends DUI charges in St. Clair County and throughout the area, using our extensive experience to effectively dismantle them at each point.
Field Sobriety Tests and Chemical Testing
Understanding what to do when you get pulled over on suspicion of DUI also matters. In Illinois, field sobriety tests are voluntary. They’re also the most biased evidence, and you are within your legal rights to refuse these tests.
The standardized tests that police officers issue for field sobriety are the Horizontal Gaze Nystagmus (HGN) test, walk-and-turn, and one-leg stand. With the HGN, the officer asks you to follow a pen with only your eyes. The other two field sobriety tests involve walking and turning, and standing on one leg.
Some people cannot perform these field sobriety tests properly while they are completely sober. Medical conditions commonly make it difficult, hence why these tests are the most subjective pieces of evidence in these cases.
Chemical tests involve testing breath or blood, and these fall under the implied consent laws. Refusing to take these tests can trigger a longer suspension of driving privileges. As a former prosecutor and experienced defense attorney, Erin K. Conner knows and has seen how breathalyzers can have calibration errors, lapses in certifications for the machines or officers, or cause rising BAC, which don’t reflect your level of intoxication while driving. There is also the chance for operator error when administering these tests. Don’t say a word if the officer is charging you with DUI except to calmly tell them you will remain silent and want an attorney. Then call our office immediately to get on the case.
License Consequences: Suspension, MDDP, and BAIID
Since a DUI involves traffic offenses as well, it helps to have an experienced Belleville traffic violations lawyer in your corner. You’re not just facing criminal charges but driver’s license complications as well. Regardless of your criminal outcome, you still have a statutory summary suspension that takes effect 46 days after your arrest unless the matter is addressed with the court.
For a first offense with a failed BAC test, you face a 6-month suspension. Refusing to take a breath or blood test doubles that suspension time to 12 months. You can apply for a Monitoring Device Driving Permit (MDDP) and get a Breath Alcohol Ignition Interlock Device (BAIID) as a first-time offender, which allows you to drive anywhere at any time during this suspension period. The BAIID prevents your vehicle from starting up if it detects BAC over 0.025%.
Attempting to start your vehicle with a BAIID that detects 0.05% or higher BAC, missing the rolling retest, or tampering with the device all trigger cancellation of this benefit. It can be a huge challenge for driver’s license reinstatement after DUI, though The Conner Law Firm will be there with you through this process to help you get back to life as you knew it before these charges.
DUI Defense Strategies That Work
Defending against a DUI charge in Belleville, Illinois, requires taking a strategic approach that deeply scrutinizes police procedures, scientific evidence, and constitutional rights. The serious penalties mean your freedom is at stake, and employing effective defense is vital for mitigating the consequences or securing a dismissal.
Challenge the Traffic Stop: Lack of Reasonable Suspicion
Illinois police officers can’t pull vehicles over without having reasonable suspicion that a driver is breaking the law. Weaving within a lane can happen to anyone even while completely sober and is very different from someone who is legitimately driving erratically.
Erin can file a motion to quash arrest and suppress evidence, especially when police dashboard cameras can prove that the violation described in the officer’s report didn’t match. This could force a dismissal of the charges.
Challenge Breath and Blood Test Accuracy
Breathalyzers must be calibrated and certified at least every 62 days in accordance with 20 Ill. Adm. Code 1286.200. Your Belleville DUI lawyer can demand to view the maintenance logs on the device to prove it was unreliable and inadmissible.
There is also a 20-minute observation rule that requires officers to continuously observe a DUI suspect for a minimum of 20 minutes before conducting this testing to ensure the sample is not contaminated by chewing tobacco, belching, or vomiting. Medical conditions such as GERD, acid reflux, and even diabetes can produce falsely high BAC readings, and the results can be challenged. Similarly, blood tests, if issued, must be handled, stored, and tested according to a precise chain of procedures. If there is any gap in these processes, it can warrant a challenge to the results, and threaten the successful prosecution of the case.
Rising BAC Defense
Since alcohol can take 30 minutes up to 2 hours to be fully absorbed in the bloodstream, there may be a rising BAC defense. In theory, your BAC may be below the legal limit of 0.08% while driving but rises by the time you are tested at the police station. When there is a major delay between the traffic stop and the actual breath test, strategies can be employed which may show you were not impaired, or not impaired to the level the state has alleged, while you were operating your vehicle.
Suppress Illegally Obtained or Improperly Collected Evidence
After arrest, it is common for officers to ask drivers they have in custody how much they’ve had to drink before they’ve read them their Miranda rights. When this happens, those statements elicited in response to the officer’s questioning become susceptible to suppression. Challenges can also be issued for field sobriety tests if they deviate from the National Highway Traffic Safety Administration (NHTSA) protocols. In certain cases, establishing actual physical control of the motor vehicle may even be a challenge for prosecutors. With Erin’s background handling cases on both the prosecution and defense, she has the knowledge and experience to know what strategies work, and how to employ them for your case.
In the event that there is strong evidence of guilt, The Conner Law Firm will shift to tactics that minimize long-term damage. First-time DUI offenders are often eligible for court supervision, which is not the same thing as a conviction. If these terms are completed successfully, the case shows as dismissed without reporting a criminal conviction to your record.
DUI charges can sometimes be negotiated down to reckless driving or another traffic infraction, which have fewer penalties than a DUI supervision or conviction. As a former prosecutor, Erin knows which evidence weaknesses matter most, and targets them to get the most favorable outcome possible in your circumstances.

Frequently Asked Questions
What to Do After a DUI Arrest in Illinois?
Remain silent and contact our office as quickly as possible. Illinois law imposes strict windows to challenge an administrative suspension based on the DUI arrest, and the sooner we get involved, the sooner we can start protecting your interests.
Should I Refuse a Breathalyzer in Illinois?
The decision is a personal one. Refusing to test will result in a suspension period that is longer than that of a failed test, but the results of a test will be used against you in a criminal prosecution. In a summary suspension proceeding, a failure to test does not alleviate the requirement that an officer have an adequate basis to suspect you of operating a motor vehicle under the influence, which is a frequent pathway to challenge the suspension.
What Happens at a DUI Booking in Illinois?
You will be transported to the local police station or county jail, where officers will process your personal information, inventory your belongings, and typically attempt to conduct chemical testing.

Should I Talk to Police During a DUI Stop?
You are required to provide your driver’s license, proof of insurance, and registration during a traffic stop, but you have the right under the Fifth Amendment to decline to answer questions about where you’ve been or how much you’ve had to drink. Politely invoking your right to remain silent is almost always the right move.
