What is a DUI in Illinois?
In Illinois, a DUI (Driving Under the Influence) is defined as operating a motor vehicle while under the influence of alcohol, drugs, or another impairing substance. Even if you don’t feel impaired, you can still face DUI charges if your BAC is 0.08% or higher.
DUI laws in Illinois also apply to drug-related impairment, including illegal substances and prescription medications that make driving unsafe.
It’s important to know that you don’t have to reach the 0.08% BAC threshold to be arrested for DUI. If your ability to drive is impaired by alcohol, drugs, or both, you can be charged with DUI regardless of your BAC.
Illinois DUI laws are found under 625 ILCS 5/11-501, which sets out how DUI is defined, how it’s prosecuted, and the penalties involved.
Types of DUI Charges in Fairfield, IL
In Illinois, DUI charges are based on the details of your arrest, your driving background, and whether any injuries occurred. Here are the most common types of DUI charges drivers face in Fairfield, IL:
First-Time DUI (Class A Misdemeanor)
A first DUI offense in Illinois is usually charged as a Class A misdemeanor. This charge carries potential penalties of up to one year in jail, fines reaching $2,500, at least a one-year license revocation, and mandatory alcohol programs.
Aggravated DUI (Felony)
A DUI can become a felony if certain aggravating factors are present. This can happen under conditions such as:
- Being arrested for DUI while transporting a child under the age of 16.
- Causing serious injury or death while driving under the influence.
- Facing charges after accumulating three or more previous DUI offenses.
- Being charged with DUI while driving with a suspended or revoked driver’s license.
The penalties for aggravated DUI are far more severe and can include prison sentences and extended loss of your driver’s license.
Repeat DUI Offenses
A second or third DUI conviction comes with increased penalties. You may face longer jail sentences, extended license revocations, and tougher probation or supervision requirements.
DUI with a Minor Passenger
Operating a vehicle under the influence while transporting a minor can result in tougher penalties, required community service, extra fines, and even felony charges.
DUI Causing Injury or Death
A DUI accident that causes serious injury, permanent harm, or death can lead to aggravated DUI charges and significant prison time.
If a DUI accident results in serious bodily injury, permanent disability, or death, you could face aggravated DUI charges and lengthy prison sentences.
Drug DUI
Illinois law allows DUI charges if you drive under the influence of illegal drugs, prescription drugs, or over-the-counter medications that impair your driving ability.
CDL DUI
If you hold a Commercial Driver’s License (CDL) in Illinois, DUI penalties are more severe. A first CDL DUI offense can cost you your CDL for at least one year, even if the arrest happened while driving your personal car. If you are convicted of a second DUI, you face permanent CDL disqualification. The legal BAC limit for CDL drivers in commercial vehicles is just 0.04%, which is half the standard limit for non-commercial drivers.
DUI Penalties in Fairfield, IL
The penalties for DUI in Illinois vary based on whether it’s your first, second, or an aggravated offense. DUI convictions can result in jail time, financial penalties, license loss, and long-term effects on your insurance and driving history.

Summary Suspension and License Reinstatement After a DUI in Fairfield, IL
Following a DUI arrest in Illinois, your license is automatically subject to a Statutory Summary Suspension before you are found guilty of anything. The suspension happens automatically if you fail or refuse a chemical test, such as a breathalyzer or blood draw.
Statutory Summary Suspension
- Failed Test (BAC 0.08% or higher): Leads to a mandatory 6-month license suspension.
- Refused Test: Results in a mandatory 12-month license suspension.
- Commercial Drivers: Your CDL can be disqualified right away, even if the arrest happened while driving your personal vehicle.
You can challenge the summary suspension by filing a Petition to Rescind. This must be done within 90 days of the notice of suspension or your first court date, whichever comes first.
Your hearing must be set within 30 days of the petition being filed or your first court appearance, whichever gives more time. If the hearing is not held in time, the suspension can be automatically dismissed.
License Reinstatement
If your driver’s license is suspended because of a DUI arrest, a DUI lawyer can support you through the following actions:
- Prepare and submit the necessary documents to fight the suspension.
- Fight for your license at reinstatement hearings.
- Pursue a Monitoring Device Driving Permit (MDDP), which allows you to drive with a BAIID device installed (if necessary).
- Help you complete the formal license reinstatement process once your suspension is over (if needed).
The sooner you act, the better your chances of minimizing the time you are without your driving privileges.
DUI Defense Strategies in Illinois
Being charged with DUI in Illinois does not mean you will automatically be convicted. A DUI defense attorney can review the evidence and create a strategy to defend your rights and protect your future. Some of the most effective DUI defense strategies include:
Challenging the Traffic Stop
Police officers must have a valid legal reason to stop you. If the stop was not supported by reasonable suspicion — such as observing erratic driving, traffic violations, or signs of impairment — any evidence collected after the stop may be excluded from your case.
Questioning Field Sobriety Tests
Field sobriety tests are not always accurate. Things like health problems, anxiety, road surface, and weather can make these tests inaccurate. Your attorney may argue that these tests do not accurately reflect impairment.
Challenging Chemical Test Results
Chemical tests like breathalyzers and blood draws must be performed correctly, regularly maintained, and handled by qualified personnel. If there are mistakes in test procedures, equipment maintenance, or the timing of the test, the BAC results can be called into question.
Challenging Observations of Impairment
Law enforcement reports typically list things like slurred speech, bloodshot eyes, and the smell of alcohol as signs of impairment. A DUI lawyer may offer other explanations for these observations that don’t involve alcohol or drug use.
Asserting Constitutional Violations
When your rights are violated — such as through an illegal search, a failure to issue Miranda warnings, or an unlawful arrest — your attorney can ask the court to exclude that evidence through a motion to suppress.
Negotiating for Reduced Charges
When appropriate, your attorney may work to have the charges reduced to a lesser offense like reckless driving or to negotiate sentencing options that minimize the long-term impact on your life.

What to Do If You Are Charged with a DUI in Fairfield, IL
Your actions right after a DUI arrest in Fairfield, IL are critical and can directly affect your case and your chances of saving your license.
Do Not Plead Guilty Right Away
Many people assume they have no choice but to plead guilty after a DUI arrest. This is a mistake. The government must prove the charges beyond a reasonable doubt, just like any other criminal case. Always speak to a DUI defense attorney before making any decisions.
Do Not Consent to Chemical Tests Until Police Get a Warrant
Field sobriety and chemical testing are tools the state uses to build a stronger case against you. The most effective way to block the state from collecting this evidence is to refuse all tests unless the police obtain a warrant. Even though police may say your license will be suspended for a year if you refuse, our Fairfield, IL DUI defense attorneys can challenge that suspension in court.
Contact a DUI Lawyer Immediately
Contacting a DUI lawyer right away gives you the best chance to fight the charges and save your license. Delays can reduce your chances of a successful defense.
Preserve Any Evidence
Gather and preserve receipts, messages, or any documents that might support your version of events, such as where you were, what you had, or who can confirm your story.
Follow Your Lawyer’s Advice
DUI cases move quickly. It’s essential to trust your attorney’s guidance and follow their strategy at every stage of the case.
