Illinois DMV Permit Practice Test

The Illinois Secretary of State knowledge test is the gateway between you and an instruction permit. Study the 2026 Illinois Rules of the Road, the state's official handbook. You have up to three attempts within one year before you need to pay again.

• ✓
  The test35 questions. Pass at 28 correct (80%). Illinois uses the same test format for all first-time drivers regardless of age.
• ✓
  Application fee$20 for the instruction permit. That covers your vision screening and up to 3 written-test attempts within a 12-month period — you don't pay again if you fail and retake within the year.
• ✓
  What to bringProof of identity (birth certificate, passport, or permanent resident card), proof of Illinois residency, and proof of your Social Security number.
• ✓
  Under 17 years 3 months?State-approved driver education is required. Applicants aged 15 up to 17 years and 2 months must be enrolled in an approved driver-ed course, or be starting one within 30 days. At age 17 years 3 months, you may skip formal driver ed.
• ✓
  Know the exact numbersKnow the specific distances and thresholds: 100 feet for turn signals in residential areas, 200 feet in open areas, 20 mph school-zone speed. Memorize the numbers, not just the concepts.

Start with traffic laws, safety, and road signs. Know every number below exactly.

• ✓
  Road signsShape, color, and meaning of regulatory, warning, and guide signs. Learn orange work-zone signs, pentagon school-crossing signs, and slow-moving vehicle triangles. Study each sign as an image, not just by its label.
• ✓
  Right-of-way and turningLeft-turn yield rules, pedestrian priority at crosswalks, yielding to white-cane / guide-dog users at all times, and roundabout priority (vehicles already in the circle have right-of-way).
• ✓
  Signal distance — 100 ft / 200 ftIn a business or residential area: signal at least 100 feet before turning. In open areas outside those districts: at least 200 feet. Know both numbers.
• ✓
  Following distance — the 3-second ruleUse the three-second rule: when the vehicle ahead passes a fixed point, count three seconds before you reach that same point. For motorcycles, use three to four seconds.
• ✓
  School-zone speed — 20 mphIn a school zone, drop your speed to 20 mph on school days from 6:30 a.m. to 4 p.m., as long as signs are posted and children are present.
• ✓
  BAC limit — age 21+: 0.08%A BAC of 0.08 percent or higher is against the law for any driver who is 21 or older and behind the wheel.
• ✓
  BAC limit — under 21: any amountIllinois has zero tolerance for drivers under 21. A test showing any alcohol (above 0.00) results in a license suspension: 3 months for a first offense, 12 months for a repeat.
• ✓
  Chemical-test refusalIf a police officer suspects you are DUI, refusing a chemical test (breath, blood, or urine) means your driving privileges will be suspended for one year on a first offense, which is longer than the six-month suspension for failing the test.
• ✓
  Open-container lawNeither the driver nor any passenger may drink from an open alcohol container or keep one in their possession while a motor vehicle is being operated on a highway.
• ✓
  Bike lanes: vehicles keep outA bike lane is reserved for cyclists. Vehicles may not drive, park, idle, or stop to drop off or pick up passengers in it, even when no cyclist is present.

These rules are easy to mix up. Learning the concept is not enough; know the exact rule.

• ✓
  Three-car right-of-way at an all-way stopAt a non-working traffic signal, treat the intersection as an all-way stop — come to a full stop and yield before entering. When multiple vehicles arrive simultaneously, yield to the vehicle on your right. Don't skip the full stop just because the signals are dark.
• ✓
  School bus — stay stopped until the bus movesTraffic in both directions must stop when the bus shows flashing red lights and its stop arm is out, except that on a four-lane roadway you need not stop for a bus stopped in the opposite direction. Stay stopped until the stop arm folds back in and the lights stop flashing, or the bus driver signals you to proceed. It is not enough that the kids are off. Passing illegally means a license suspension plus a mandatory $300 fine.
• ✓
  Hill parking — downhill: wheels toward the curb (or road edge)Whether or not there is a curb, a car facing downhill should have its front wheels turned to the curb or the road's edge, so that it rolls into the curb rather than into traffic.
• ✓
  Hill parking — uphill with a curb: wheels away from curbFacing uphill with a curb: turn wheels away from the curb. If brakes fail, the car rolls back into the curb and stops. Uphill without a curb: turn wheels toward the road edge.
• ✓
  Impairment can start below 0.08%Any amount of alcohol affects judgment and physical coordination — even a BAC lower than the legal limit. Don't confuse 'impaired' with 'illegal per se.'
• ✓
  Always yield to white-cane usersAt all times, you must give way to a pedestrian who has a white cane or a guide dog; traffic signals and right-of-way create no exceptions. This is one of the few absolute 'always' rules.
• ✓
  Bike lanes are off-limits to vehiclesVehicles are not allowed to drive, park, idle, or drop off or pick up passengers in a bike lane, even if no cyclist is present. Before turning right, check for bicyclists approaching the intersection.

Reading the handbook once may not be enough to pass. Try three loops: read once, drill once, listen once. That's it.

• ✓
  Loop 1 — read the handbookDownload the Illinois Rules of the Road (Form DSD A 112) free from ilsos.gov. Read it once end-to-end — about 2 hours. Don't highlight; your brain will mark what surprises you, and those are the points to revisit.
• ✓
  Loop 2 — drill the practice examsTake the free 40-Q exam below cold. Anything under 32/40 → go back and drill that category specifically. Retake the practice exams until you're passing comfortably before test day.
• ✓
  Loop 3 — listen along on YouTubePlay the Illinois Cheat Sheet video the night before your test. Hearing the key facts read aloud reinforces pattern recognition — the same voice in your head during the exam.
• ✓
  Sleep beats crammingA rested brain processes faster and second-guesses less. If you're hitting 80%+ on practice runs, stop studying the night before and get 7–8 hours.
• ✓
  Study signs visuallySigns are visual, so study the actual images. Flashcards with descriptions won't cut it. Use visual practice tools — or replay the Road Signs video and pause on each sign.
• ✓
  Read every optionRead every option before you choose. When you see 'All of the above,' verify each option before choosing it.

Passing the knowledge test gets you an instruction permit — not a full license. Illinois's Graduated Driver Licensing rules include a hard minimum hold time, supervised-hours requirements, and a curfew that changes depending on the day of the week.

• ✓
  Who must supervise youA licensed adult age 21 or older must ride in the front passenger seat. They need at least one year of driving experience and a valid license for the type of vehicle. Can be a parent, guardian, family member, or responsible adult.
• ✓
  Minimum permit hold — 9 monthsYou cannot be issued a driver's license until you've held the instruction permit for at least 9 consecutive months. This is a hard floor: no exceptions for early licensing.
• ✓
  Supervised practice hours — 50 total, 10 at nightLog a minimum of 50 hours of supervised driving before you can be licensed, with at least 10 of those hours after dark. Night hours count toward the 50-hour total, not in addition to it.
• ✓
  Night curfew — different on weekdays vs. weekendsDuring the initial licensing phase (ages 16–17): Sunday through Thursday, no driving from 10 PM to 6 AM. Friday and Saturday, the curfew shifts to 11 PM to 6 AM. This split schedule is easy to mix up.
• ✓
  Passenger restriction — first 12 months (or until 18)For the first 12 months of your initial license, or until you turn 18 (whichever comes first), you may carry at most one passenger under age 20, unless any others are siblings, step-siblings, children, or stepchildren of the driver. All passengers must wear safety belts. A conviction during the first year keeps the limit in place until you have gone 6 months in a row without one.
• ✓
  When restrictions lift — age 18The passenger limit above runs for the first 12 months or until you turn 18, whichever comes first. The other restrictions end when you turn 18, provided you have been conviction-free for the 6 months before your 18th birthday. A traffic conviction during the initial licensing phase may extend them beyond age 18.
