What is the legal blood alcohol concentration (BAC) limit for drivers over 21 in Illinois?

In Illinois, the legal blood alcohol concentration (BAC) limit for drivers aged 21 and over is set at 0.08%. This regulation is established to ensure public safety by limiting the amount of alcohol that can impair a driver's ability to operate a vehicle safely. At this level, a driver's motor skills, judgment, and reaction times are significantly affected, increasing the risk of accidents.

Drivers under the age of 21 are subject to a zero-tolerance policy, meaning any detectable alcohol in their system can lead to legal penalties. Understanding this legal limit is crucial for all drivers to avoid not only penalties but also the potential dangers that arise from impaired driving.
