How to get your Illinois driver's license

The knowledge test is one step in Illinois's licensing process. Here's how the path typically works for a new driver.

1. 1

   Check the age and eligibility requirements

   Eligibility in Illinois: 15 with driver's education enrollment for an instruction permit, 16 for an initial license. Have your proof of identity, residency, and any required parental consent ready.

2. 2

   Study the official handbook

   Read the Official Illinois Rules of the Road (ilsos.gov) and practice with DMV Ace until you're consistently scoring above 80%.

3. 3

   Pass the knowledge test

   The Illinois written test has 35 questions, and you need 28 correct (80%) to pass. You have 60 minutes. Permit/licensing fee: $20.

4. 4

   Build supervised driving experience

   Hold your permit for the period Illinois requires and log supervised driving hours with a licensed adult before you schedule the road test.

5. 5

   Pass the road test and get licensed

   After you pass the behind-the-wheel road test, Illinois issues your driver's license — often an intermediate/provisional license first for younger drivers.

Steps are a general guide — always confirm the current process with your local Illinois DMV office.
