Driver's License Test Prep
Illinois Practice DUI & Impaired Driving

A driver age 20 is stopped and found to have a small amount of alcohol in their system, though under .08. Under Illinois law, this driver's license will be suspended for at least:

  1. A.
    Three months Correct
  2. B.
    Six months
  3. C.
    One year
  4. D.
    One month
The Why

The answer is "Three months"

For any driver under 21, any trace of alcohol carries a minimum three-month suspension of driving privileges. Six months is the trap: that's the adult failure-of-test length, and drivers who default to the adult rule instead of the under-21 zero-tolerance rule land there.

Why the others miss

The traps in the wrong answers

B. Six months

Six months is the adult chemical-test failure length, not the under-21 zero-tolerance length. This answer applies the adult failed-test rule to a driver under 21 whose test came back below .08.

C. One year

One year is the chemical-test refusal length, not the under-21 zero-tolerance suspension. This answer applies an adult-rule figure to the under-21 scenario, on the habit that any alcohol-related stop draws a suspension of at least a year.

D. One month

One month is shorter than any suspension length the manual sets for alcohol offenses under 21. This answer guesses a lenient floor on the assumption that under-21 rules only apply at .08 and above.
