Defining DUI in Illinois
In Illinois, a driver is considered under the influence if their ability to operate a vehicle is impaired due to alcohol, drugs, or a combination of both. This includes legal prescription medications that may impair your driving ability. It’s essential to understand that you can still face DUI charges even if you have a valid prescription for the medication causing the impairment.

Blood Alcohol Concentration (BAC) Limits
Illinois has specific BAC limits that determine whether a driver is considered legally impaired. For drivers 21 and older, the limit is 0.08%. For commercial drivers, it’s lower at 0.04%, and for drivers under 21, it’s 0.00%. However, if you show signs of impairment, you may still be charged with a DUI, even if your BAC is below the legal limit.

DUI Penalties and Sentencing
The consequences of a DUI conviction in Illinois vary based on the number of previous offenses, the driver’s BAC level, and other factors. Penalties may include fines, jail time, community service, alcohol education programs, and license suspension or revocation. For example, a first-time DUI offense can result in a one-year license suspension, while a third offense may lead to a 10-year suspension.
Implied Consent and Breathalyzer Tests
Illinois has an implied consent law, which means that when you obtain a driver’s license, you automatically agree to submit to chemical testing if you’re suspected of DUI. Refusal to take a breathalyzer or other chemical test can result in an automatic license suspension, even if you are not found guilty of DUI.

Restricted Driving Permits and Monitoring Device Driving Permits
After a DUI conviction, you may be eligible for a Restricted Driving Permit (RDP) or a Monitoring Device Driving Permit (MDDP) to regain some driving privileges. An RDP allows you to drive for specific reasons, such as work or medical appointments, while an MDDP requires you to install a Breath Alcohol Ignition Interlock Device (BAIID) in your vehicle.
Preventing DUIs: Tips for Staying Safe
To avoid DUIs and the associated penalties, it’s important to take precautions when consuming alcohol or using medications that could impair your driving. Designate a sober driver, use public transportation, or call a rideshare service if you’ve been drinking. Be aware of the side effects of your medications and consult your doctor if you’re unsure about their potential impact on your driving ability.
