What is the minimum revocation period for a first DUI conviction in Illinois?

  1. A.
    Six months
  2. B.
    Two years
  3. C.
    Ninety days
  4. D.
    One year Correct
The Why

The answer is "One year"

The manual sets a first DUI conviction at a minimum one-year revocation of driving privileges. Six months is the trap: that's the statutory summary suspension for failing chemical testing, a separate administrative penalty, and drivers who fold the summary suspension and the court revocation into one number pick the shorter one.

Why the others miss

The traps in the wrong answers

A. Six months

Six months is the statutory summary suspension imposed when chemical testing discloses a prohibited BAC, THC, or controlled-substance result, a separate administrative penalty from the court-ordered DUI revocation. This answer grabs the six-month figure printed one section earlier in the same chapter and treats it as the DUI answer without noticing it labels the pre-conviction penalty, not the sentence a court imposes.

B. Two years

Two years is the minimum revocation for a first DUI conviction of a driver under age 21, not the adult figure. This answer applies the doubled under-21 first-conviction minimum to an adult driver by treating the youth penalty as the general rule.

C. Ninety days

Ninety days is not a revocation period tied to any DUI conviction in the Illinois manual. This answer borrows the three-month under-21 zero-tolerance suspension for any trace of alcohol and misapplies it as the adult DUI revocation floor.
