Is it legal for persons under 21 years of age to drive with any traces of alcohol in their system?

Individuals under 21 years of age are prohibited from having any measurable amount of alcohol in their system while operating a motor vehicle. This law is part of a broader strategy to reduce drunk driving incidents and protect young drivers who are statistically more likely to be involved in alcohol-related accidents.

The zero-tolerance policy reflects the understanding that even small amounts of alcohol can impair a driver’s ability to operate a vehicle safely. Consequently, law enforcement can take action if they detect any alcohol in the system of someone under 21, leading to legal penalties, including fines and potential suspension of driving privileges.

Other options implying exceptions, such as parental consent or supervision, are not applicable under Illinois law, as any presence of alcohol is prohibited regardless of circumstances.
