Illinois Permit Test 2026: Score, Rules, and Practice
The Illinois permit test is a 35-question exam split into two parts: 20 questions on traffic laws and 15 on road sign identification. You need 28 correct, an even 80 percent, and you take it in person at a Secretary of State Driver Services facility, the offices Illinois now calls the DMV. There is no online option for the knowledge exam, and the $20 instruction permit fee already covers it. That part is straightforward. What catches people off guard is everything wrapped around the test: a driver education rule that decides whether you can sit for it at all, a nine-month holding period after you pass, and 50 hours of logged practice. This guide walks through the score, the fees, and the full Illinois pipeline so nothing surprises you at the counter.
What is on the Illinois permit test
The exam asks 35 multiple-choice questions. Twenty cover the rules of the road, right of way, speed limits, parking, and alcohol law. The other 15 ask you to identify traffic signs by shape, color, or meaning, so the sign half is worth nearly half your grade. You pass at 28 correct and fail at 27, the same flat 80 percent threshold Illinois applies to the written exam. The law questions lean heavily on right-of-way order, posted and statutory speed limits, and the zero-tolerance alcohol rules that apply to every driver under 21, so those topics repay extra study.
You take the knowledge test in person. Unlike the at-home options in some states, the Illinois knowledge exam runs only at a Driver Services facility, where a vision screening at the counter is part of the same visit. Miss the cutoff and you can usually retake the test the same day during business hours, which is gentler than the multi-day waiting periods built into other state systems. Bring time as well as paperwork, because the vision check, the photo, and the written exam all happen in one counter visit rather than across separate appointments.
For comparison, the California permit test runs 46 questions with 38 needed to pass, and the Texas knowledge exam is 30 questions at 70 percent, so Illinois sits in the middle on length but demands a higher percentage than Texas. Drilling Illinois-specific questions first on the Illinois practice test is the fastest way to learn the local wording.

Fees, facilities, and the new DMV name
The instruction permit costs $20, and that single fee covers the application, the vision screening, the written exam, and the permit card itself, which is printed the same day if you pass everything. The full driver’s license fee comes later and depends on your age, which is where Illinois rewards younger drivers with a much smaller charge.
| Illinois fee | Cost |
|---|---|
| Instruction permit (all ages) | $20 |
| Driver’s license, age 18 to 20 | $5 |
| Driver’s license, age 21 to 68 | $30 |
| Driver’s license, age 69 to 80 | $5 |
| Driver’s license, age 81 to 86 | $2 |
| Driver’s license, age 87 and older | Free |
One quirk worth knowing before you go: Illinois has no separate Department of Motor Vehicles. Driver and vehicle services sit under the Secretary of State, but since 2023 the office has labeled its facilities DMV locations for clarity, and it opened a flagship DMV in the Chicago Loop in April 2025. The agency is the same one Illinois drivers have always used, so a search for either name lands you in the right place. You schedule the visit and find your nearest facility through the official Secretary of State site, then bring proof of identity, residency, and your Social Security number.
The driver education rule most people miss
Here is the part the practice-question sites skip, and it decides whether you can even take the test. For drivers under 18, the instruction permit is tied to driver education. Under section 625 ILCS 5/6-107.1 of the Illinois Vehicle Code, a 15-year-old can be issued a permit only when enrolled in an approved driver education course and needs the permit to take part in it. You do not walk in at 15 and test cold. A teen can get a permit without driver education only once they reach 17 years and 3 months.
Adults are not automatically exempt either. Public Act 98-167 requires Illinois license applicants who are 18, 19, or 20 and who have never held a license and never completed driver education to finish a six-hour Adult Driver Education course first, according to the Secretary of State’s Adult Driver Education program. An adult who assumes a clean walk-in test, the way it works in many states, can be sent away to complete the course before testing. If you are an adult starting late, our guide to the minimum permit age in every state shows how Illinois compares.
After you pass: the nine-month permit phase
Passing the test starts a clock, it does not stop one. Drivers under 18 enter the permit stage of Illinois graduated driver licensing, and the rules here are stricter than most newcomers expect. You must hold the permit for a minimum of nine months before you are eligible for the next license, and you must log 50 hours of supervised practice, including 10 hours at night, with a parent or a licensed adult who is at least 21.
The clean-record condition is the one that bites. According to the Secretary of State’s graduated licensing rules, you cannot acquire any driving conviction during the nine-month permit phase, and the supervising adult must occupy the front seat at all times. A single ticket can restart the clean window and push your license date back. Logging the hours as you go is far easier than reconstructing them later, which is why a printed supervised driving hours log matters. For the full state-by-state picture, see how the permit holding period varies and where Illinois fits in the broader graduated licensing stages.
| Illinois permit phase, under 18 | Requirement |
|---|---|
| Minimum permit age | 15, with driver education enrollment |
| Minimum holding period | 9 months |
| Supervised practice hours | 50 total, including 10 at night |
| Supervisor requirement | Parent or licensed adult age 21 or older, front seat |
| Driving convictions allowed | None during the 9-month phase |
| Driver education | Approved course required |
Night, passenger, and phone rules for new drivers
Two restrictions follow Illinois teens past the permit and into the first license. The nighttime driving curfew runs from 10 p.m. Sunday through Thursday and from 11 p.m. Friday and Saturday, ending at 6 a.m., though some local curfews start earlier. For the first 12 months of licensing, or until the driver turns 18, whichever comes first, only one passenger under 20 may ride along unless the extra passengers are siblings, stepsiblings, or the driver’s own children.
Phones are off limits longer than many families realize. Drivers under 19 cannot use a cellphone while driving, including a hands-free device, except in an emergency. These limits are not arbitrary. Federal research on passenger restrictions for new drivers found a 20 percent lower fatal crash rate for 16-year-olds when no more than one young passenger was allowed, and the Insurance Institute for Highway Safety lists Illinois among the states with strong graduated licensing on these exact points. Knowing the right of way at uncontrolled intersections matters even more once a curfew limits your supervised night practice window.
The mistake that resets the clock
Picture Devon, a 15-year-old in Naperville who passes the written exam, logs hours all spring, and is counting down to a September license. In month seven he rolls a stop sign on the way to practice and gets cited. That conviction lands inside the nine-month clean-record window, so the clock on his unrestricted-record requirement restarts, and his license date slides into the next year. The test was never the hard part for Devon; the months after it were.
The fix is boring and effective. Treat the entire permit period as a probation on your own record, drive the night curfew as if it were a hard wall, and over-practice the items teens fail most, like the four-way order at a stop sign and the difference between regulatory and warning signs in the road sign library. A clean nine months is worth more than a fast nine months.
How to study and pass on your first try
Build your prep around the test’s actual shape. Fifteen of the 35 questions are signs, so spend real time on sign shapes and colors rather than only reading rules. Work through the official 2026 Rules of the Road, then drill timed practice sets until you are clearing 90 percent consistently, which gives you margin above the 28-correct line on test day. Pay attention to the questions you miss twice, since a repeated error usually means you learned a rule wrong rather than simply forgot it, and those are the ones that resurface on the real exam.
Practice with the state selected so the wording, fees, and limits match what Illinois actually asks, using the Illinois practice questions and browsing other state permit guides if you plan to move. In the DMV Ready app you can run full Illinois practice exams that mirror the 35-question format, drill the signs you keep missing, and track your readiness so you walk into the facility knowing you are over the line, not hoping you are.
