Overview of the Illinois Zero Tolerance Law

Illinois’s zero-tolerance law, also known as the Use It & Lose It Zero Tolerance law, is designed to prevent underage drinking and driving. In simple terms, if you are underage and are caught driving with any measurable amount of alcohol in your system, you face strict penalties even if your blood alcohol concentration (BAC) is below the legal limit for adults.

This law applies not only when a driver under 21 is actively operating a vehicle but also when they are in physical control of it, even if the car isn’t moving. This means law enforcement can enforce penalties anytime an underage driver has alcohol in their system while behind the wheel or seated in a way that could allow them to drive.

The law works hand-in-hand with the Illinois Vehicle Code and the Graduated Driver Licensing program, aiming to protect teen drivers, passengers, and the public from accidents related to alcohol-impaired driving.

Key Provisions of the Law

Blood Alcohol Content (BAC) Limitations

Under Illinois’s zero-tolerance law:

  • Drivers under 21 cannot have a blood-alcohol concentration (BAC) of 0.01% or higher while driving.
  • Law enforcement officers may request chemical testing, including breathalyzer, blood tests, or urine tests, during a traffic stop if there is probable cause.
  • Refusing a chemical test can lead to an automatic driver’s license suspension under the Implied Consent Law.

License Suspension Penalties

Penalties for underage drivers are strict:

  • First offense:
    • Driver’s license suspension up to 1 year
    • Court supervision or alcohol education programs
    • Possible community service
    • Reinstatement fees required at the Illinois Secretary of State office
  • Second offense:
    • Longer driver’s license revocation
    • Mandatory alcohol education programs
    • Possible ignition interlock device installation
    • Higher reinstatement fees and insurance rate increases

Additional Legal Consequences

Beyond license issues, underage DUI charges can affect:

  • Insurance premiums due to public driving records
  • College admissions and future employment opportunities
  • Car insurance costs and eligibility for SR-22 insurance
  • Potential criminal charges if the DUI involves injury or property damage (personal injury cases)

Comparing Zero Tolerance and Standard DUI Laws

While both underage DUI and adult DUI laws aim to prevent impaired driving, there are key differences:

Key Differences:

  • BAC threshold: Adult drivers face DUI charges at 0.08% BAC, while underage drivers can face zero-tolerance penalties at 0.01% BAC.
  • License suspensions: Adults may face license revocation, but underage drivers face almost immediate suspension of driving privileges.
  • Criminal vs administrative penalties: Underage drivers often receive court supervision instead of full criminal penalties for a first offense, but repeat violations can trigger criminal charges.

Implications for Teenage Drivers:

Even a single drink, like at a party or a celebration, can result in license suspension and other long-term consequences. Traffic stops, breathalyzer tests, or even probable cause observations by a law enforcement officer can start the process.

Consequences of Violating the Law

Violating the zero-tolerance law can ripple through many areas of your life:

Educational and Career Impacts:

  • College admissions may consider DUI convictions in applications.
  • Violations can restrict eligibility for student driving programs or campus parking privileges.

Insurance Ramifications:

  • Car insurance costs can spike after a traffic citation or DUI charge.
  • SR-22 insurance may be required for reinstatement of a driver’s license.

Criminal Records and Public Driving Record:

  • Even under court supervision, your driving record is affected.
  • Repeat offenses can result in aggravated DUI charges, leading to criminal prosecution and long-term public intoxication concerns.

Other Penalties:

  • Nighttime driving restrictions for teens
  • Mandatory driver remedial education courses
  • Community service or alcohol education programs
  • Potential towing fees if a vehicle is impounded

Under Illinois Vehicle Code (625 ILCS 5/11-501.8), any driver under 21 who has any trace of alcohol in their system can face an immediate driver’s license suspension.

Facing underage DUI charges can be overwhelming, but a thoughtful defense strategy can help mitigate consequences. Experienced DUI attorneys like those at Dohman Law Group focus on several approaches:

Role of DUI Attorneys:

  • Review police reports and traffic stop details

Challenging Traffic Stops:

  • Implied Consent Law violations can affect the admissibility of breathalyzer or blood tests.

Negotiating Alternative Solutions:

  • Requesting court supervision programs instead of formal charges
  • Negotiating plea bargains or restricted driving permits
  • Enrolling in alcohol education programs to demonstrate responsibility

Parental Involvement and Responsibility:
Parents can play a key role by:

  • Supporting compliance with license suspensions
  • Attending court hearings and driver remedial education courses
  • Helping with community service or alcohol education programs

Post-Violation Actions:

  • Filing for driver’s license reinstatement at the Illinois Secretary of State office
  • Paying all reinstatement fees and completing mandatory programs
