TOP 15 ILLINOIS DUI QUESTIONS ANSWERED

The Call I Get Most Often

You were just arrested for DUI. You are sitting in your car, or at the police station, or at home — and your mind is racing. You have a thousand questions and no idea where to start. When the call comes the question is always the same – a listing of facts and ends with “What should I have done?”

I get these calls constantly. After years as a felony prosecutor and years defending DUI cases in Will County and DuPage County, I have heard every question. The same fifteen questions come up again and again.

Here are honest answers to all of them. Not the answers designed to scare you into hiring a lawyer. The truth — because that is how I operate.

About Your Arrest

1. Do I Have to Answer the Officer’s Questions?

No. You are required to provide your name, driver’s license, and proof of insurance. That is it. You have a Fifth Amendment right to remain silent beyond those basics.

This does not mean being rude or combative. It means having the self-awareness of this is going beyond a routine traffic stop.  Its means keeping calm and understanding the police will use pressure.  It means understanding that standing up for yourself today means possibly getting arrested, but tomorrow is another day to fight. It means being polite and saying: “Officer, I am going to respectfully decline to answer questions without my attorney present.”  

Everything you say is recorded — on body cameras, dash cameras, and in police reports. Statements made at the scene are used against you in court. In several of our recent Will County DUI victories, client admissions were a central part of the prosecution’s case. In each instance, we successfully argued around them — but it is far easier to win when there are no damaging admissions to overcome.

2. The Officer Didn’t Read Me My Miranda Rights. Is My Case Dismissed?

This is one of the most common misconceptions in DUI law. Miranda rights — the right to remain silent and the right to an attorney — only apply when you are in custody and being interrogated.

Most DUI arrests involve roadside questioning that occurs before you are formally placed in custody. Courts have consistently held that Miranda does not apply to that pre-arrest questioning. So no — the absence of a Miranda warning does not automatically dismiss your case.

However, if you were questioned after arrest without being Mirandized, those statements may be suppressible. This is exactly the kind of issue we examine in pre-trial motions.

3. What Happens If I Was Arrested But Not Charged Yet?

This is common. The officer arrests you, takes you to the station, processes you, and releases you — but no formal charges have been filed yet. The State’s Attorney has up to 18 months (for a misdemeanor) to file charges after an arrest.

Do not wait. Evidence is being gathered, body camera footage exists, and the summary suspension clock is already running. Contact a DUI attorney immediately — even before formal charges are filed. The earlier we get involved, the better positioned we are.

Most of the time, if you are arrested for a DUI, you will get the proper paperwork that shows you have a charge that you need to deal with.  Move fast to talk to an attorney to make sure the proper evidence is save.

4. Can I Be Charged With DUI Even If I Wasn’t Driving?

Yes — under Illinois law, the charge is DUI or “driving under the influence,” but the statute actually covers being in actual physical control of a vehicle. Courts have found actual physical control when someone was parked, sleeping in the driver’s seat, with the engine running.

However, actual physical control is not the same as driving — and that distinction is a legitimate defense. This can be a very tough argument to make because many times while the person is pulled over and parked safely, there is enough legal indicators that support the facts of “actual physical control.”

Breath Tests & Field Sobriety Tests

5. Should I Have Refused the Breath Test?

This is the question I get most a lot. The answer is nuanced — but below is the short, honest version.  Here is the long, honest version.

In most cases, refusing the breath test is strategically advantageous.

Here is why: Illinois’s implied consent law requires you to submit to chemical testing if lawfully arrested for DUI. Refusing triggers an automatic statutory summary suspension — 12 months for a first refusal, 3 years if you have a prior DUI arrest or disposition within 5 years. That is the penalty for refusing.

But the prosecution’s most powerful piece of scientific evidence in a DUI case is the breath test result. Without it, they are left with officer observations, field sobriety tests, and physical indicators — all of which are more easily challenged than a number printed on a machine.

In four of our five recent Will County victories, clients refused chemical testing. Three were found not guilty at trial. One had his suspension rescinded.

The best advice in the long run: refuse all testing. But every situation is different, and you should call an attorney the moment you are stopped if possible. Some people will do the mental math in their head of what they drank, ate, over what time, and they convince themselves they are under a .08.  They aren’t. Once the cuffs come out, you have been arrested for a DUI – that arrest is enough for the charge. You aren’t talking or blowing your way out of an arrest that that point.

6. I Blew Under .08. Can I Still Be Charged?

Yes. Illinois has two separate DUI statutes. One prohibits operating a vehicle with a BAC of .08 or more. The other prohibits operating a vehicle while under the influence of alcohol — regardless of BAC. A person can be charged under the second statute even with a BAC of .05 if the officer believes they were impaired.

Conversely, a BAC of .08 or higher does not guarantee conviction. The breath test result can be challenged and suppressed if the underlying arrest lacked probable cause — exactly as we did in the I-55 case where our client blew .086 and was found not guilty.

You can be under a .08 and still get charged.  With legal cannabis and other valid substances, you can be charged with DUI by being under the combined influence of Drugs and Alco

7. Can I Refuse Field Sobriety Tests?

Yes — and unlike the breath test, refusing field sobriety tests carries no automatic legal penalty in Illinois.

Field sobriety tests — the Walk and Turn, One Leg Stand, Horizontal Gaze Nystagmus (HGN), and others — are voluntary. You are not required to perform them. Officers often present them as if they are mandatory. They are not.

These tests are administered on the side of the road, often at night, on uneven surfaces, with traffic passing by, under significant stress. They are graded subjectively by an officer who has already decided to investigate you for DUI. Refusing eliminates a layer of evidence the prosecution would otherwise use against you.

8. I Failed the Field Sobriety Tests. Is My Case Hopeless?

No. Not even close.

Field sobriety tests are not scientific proof of intoxication. They are one officer’s observation, graded on criteria developed decades ago, affected by dozens of non-alcohol factors: fatigue, anxiety, medical conditions, poor footwear, uneven surfaces, and testing conditions.

In two of our recent Will County cases, clients scored 6 out of 6 on the HGN test — the maximum impairment score. Both were found not guilty at trial. A perfect impairment score on a field test is beatable. FSTS are only one part of a full and through DUI investigation.

9. What Is the Difference Between a PBT and the Evidential Breath Test?

There are two breath tests used in Illinois DUI investigations:

The Preliminary Breath Test (PBT) is the roadside breathalyzer — the small handheld device the officer uses before making an arrest decision. Its result is not admissible as evidence of BAC at trial. It is used only to establish probable cause for arrest. You can refuse a PBT, though refusal may be noted by the officer, and may arrest regardless of the result.  Refusing this makes it easier to challenge the underlying DUI arrest.

The Evidential Breath Test is administered at the police station on a certified breathalyzer. This result is admissible at trial. This is the test that triggers the summary suspension if refused. This is the test we challenge via motions to suppress. This is the test that is most often used to secure guilty findings on DUI charges. While refusing this test will result in a  longer suspension, a DUI disposition can hurt even more.

License & Suspension

10. What Is a Statutory Summary Suspension?

A statutory summary suspension is an automatic administrative suspension of your driver’s license that is separate from your criminal DUI case. It is triggered the moment you are arrested for DUI and either fail or refuse chemical testing.

It takes effect automatically on the 46th day after your arrest unless you successfully petition to rescind it. For a first-time refusal, the suspension is 12 months. For a second offense or prior DUI within 5 years, it is 3 years.

The critical thing to understand: this is a completely separate proceeding from your criminal case. You can win your summary suspension hearing and still face criminal charges — or lose the criminal case and have your suspension rescinded. They run independently.

You have 90 days from the date of arrest to file a petition to rescind. Do not let that deadline pass.

11. What Happens If I Just Ignore the Suspension?

The suspension takes effect automatically on day 46 whether you do anything or not. Driving on a suspended license is a separate criminal offense in Illinois — a Class A misdemeanor, which carries up to 364 days in jail and a $2,500 fine. If you are pulled over while suspended, you will face additional charges stacked on top of your original DUI.

Beyond the legal consequences, driving on a suspended license while awaiting DUI trial is the kind of conduct that will significantly harm your case and your credibility in front of a judge.

File the petition. Fight the suspension. Take the steps to drive just in case. That is what we are here for.

12. Can I Get a Driving Permit During My Suspension?

Possibly. If you are a first-time DUI offender (no DUI arrests or dispositions in the last 5 years) , you may be eligible for a Monitoring Device Driving Permit (MDDP) — which allows you to drive during your suspension period with a Breath Alcohol Ignition Interlock Device (BAIID) installed in your vehicle.

Clients always confuse what first-time DUI offender means.  There are two real definitions.  The first – and the one the Illinois Secretary of State uses when granting MDDPs – is have you had a DUI summary suspension or DUI disposition in the last 5 years.  If yes, you are a second-time offender.  If no, you are a first timer.  The bottom line, is if its been between 5-7 years or less, you may face more severe consequences for refusing. You need to act fact as second timers can’t get an MDDP.

The second definition is for criminal and sentencing law.  Anyone who has a DUI disposition either in-state or similar out of state or a reckless driving and gets a new DUI cannot get supervision, they can only get a conviction. While convictions aren’t good, the worst part is that the Illinois Secretary of State will revoke your DL upon a DUI conviction.  That’s why refusing the breath test is the best, long term, advice.

If you are a repeat offender, MDDP eligibility is more restricted. An attorney can evaluate your specific situation and determine what relief is available. Call us at (815) 717-4015 to discuss your options.

The Court Process

13. What Happens at My First Court Date?

Your first court date is called an arraignment. It is typically a brief hearing — often 10 minutes or less. The judge will formally read the charges against you, and you will enter a plea of not guilty. Almost every DUI defendant pleads not guilty at arraignment — this is standard procedure and does not commit you to anything.

The arraignment is not a trial. No evidence is presented. No witnesses testify. You will not be found guilty or not guilty at this hearing.

What happens at the arraignment matters less than what happens before it. If you have an attorney, we will have already begun reviewing discovery, identifying motion issues, and building your defense strategy before you ever set foot in the Will or DuPage County courthouse.

14. How Long Does a DUI Case Take?

It depends on the complexity of the case, whether it goes to trial, scheduling, and a million other factors. Do not let timeline pressure drive your decision. A rushed plea deal that results in a DUI conviction follows you permanently — on your criminal record, your driving record, and your insurance rates. Taking the time to build a proper defense and fight the case is almost always worth it. Preparation is what leads to the best outcomes. Some clients had their cases over in 6 weeks, some took years.  Every case is different and requires the right, unique approach.

Outcomes & Consequences

15. What Are the Penalties for a First-Time DUI in Illinois?

A first-time DUI in Illinois is a Class A misdemeanor, which carries:

• Up to 364 days in jail (though jail is uncommon for first offenses)
• Fines up to $2,500 plus court costs
• Mandatory minimum 100 hours of community service if sentenced to supervision
• Mandatory drug and alcohol evaluation and treatment if recommended
• 1-year revocation of driving privileges upon conviction
• Possible supervision (not a conviction if successfully completed) for eligible first-time offenders

An aggravated DUI — which includes cases involving a BAC of .16 or higher, a minor passenger, a prior DUI conviction, or other aggravating factors — can be charged as a felony.

The most important thing to understand about DUI penalties: a conviction is permanent. Unlike some criminal matters, DUI convictions in Illinois cannot be expunged from your record. That is why fighting the case — including the summary suspension, the underlying charges, and every procedural defect — matters so much.

Your Case Is Not Over

I have seen clients walk into my office convinced they had no chance. 117 MPH. A .086 breath test. An admission of “I need to sober up.” A three-year suspension with prior DUI history. We won every single one of those cases in the first week of February 2026 alone.

The questions you are asking right now are the right questions. The next step is making the call.
