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

Answer: A — 0.00%

In Illinois, the blood alcohol concentration (BAC) limit for drivers under 21 is set at 0.00%. This means that individuals in this age group are not legally allowed to have any measurable amount of alcohol in their system while operating a vehicle. The rationale behind this strict limit is to promote safety and reduce the risks associated with drinking and driving among younger, less experienced drivers. This zero-tolerance policy is aimed at preventing alcohol-related accidents and encouraging responsible behavior among teen drivers, who may not yet have the maturity or experience to make safe decisions when alcohol is involved.
