Illinois Driver's License Practice Test — Scott's Law, SOS Licensing, and Teen Phone Restrictions

Illinois's constitution assigns certain ministerial functions — including motor vehicle regulation and driver licensing — to independently elected constitutional officers rather than executive agencies. The Secretary of State has handled driver licensing since Illinois reorganized its government in the 1970s. This means the SOS, currently Alexi Giannoulias, is accountable directly to voters for licensing operations. Illinois is one of only a few states (including Michigan) where the SOS issues driver's licenses rather than a DMV or department of transportation.

Scott's Law (625 ILCS 5/11-907) has a three-tier fine structure. Standard violations: $250 minimum for a first offense; $750 minimum for a second or subsequent offense. Construction zone violations where workers are present: minimum $10,000 fine. These construction-zone fines are among the highest in the country for a Move Over violation. Scott's Law also extended in 2017 to cover highway maintenance and construction vehicles, not just traditional emergency vehicles. The law is named after Chicago firefighter Scott Gillen, killed at a crash scene in December 2000.

Illinois Probationary License holders under 18 face a 10 PM to 6 AM nighttime driving curfew on Sunday through Thursday. But on Friday and Saturday nights, the curfew begins at 11 PM instead of 10 PM — a one-hour extension. This weekend exception is specifically tested on the Illinois knowledge exam because applicants commonly assume the curfew is uniform every night and are surprised by the Friday/Saturday distinction. After the first year of the Probationary License without serious violations, all GDL restrictions are lifted.

Illinois drivers under 19 are prohibited from using any electronic communication device while driving — including hands-free Bluetooth calls, earpieces, and speakerphone. This is stricter than the adult rule, which permits hands-free calling. The under-19 ban was designed to prevent any distraction, not just manual interaction. Adult drivers 19 and older may use hands-free devices but cannot hold any device while driving. A first offense for a teen driver carrying a $75 civil fine; the fine does not add license points for the first three offenses.

Illinois zero tolerance for drivers under 21 means any detectable trace of alcohol — not 0.02%, but literally any amount — is a violation. A first offense results in a 3-month statutory summary suspension; a second offense results in a 6-month suspension. If the driver refuses a breath test, the suspension doubles. Unlike states such as Virginia or Michigan that set a 0.02% underage threshold (acknowledging measurement error), Illinois makes no such concession — the standard is truly zero.

Illinois requires teens under 18 to hold an Instruction Permit for a minimum of 9 months before applying for a Probationary License — one of the longer nationally mandated holding periods. During those 9 months, the teen must complete at least 50 hours of supervised driving with a licensed adult 21 or older in the vehicle, including at least 10 of those hours at night. Driver education (approved classroom and behind-the-wheel course) must be completed before the permit is issued.

Illinois fines for handheld electronic device use (625 ILCS 5/12-610.2): first offense $75; second offense $100; third offense $125; fourth and subsequent offenses $150. Critically, the first three violations are civil penalties only and do not add demerit points to the driver's license. Starting with the fourth violation, the offense becomes a moving violation that adds license points. This escalation to a point-bearing offense on the fourth violation is unique among Illinois's phone law provisions.

Yes. All first-time drivers under 18 in Illinois must complete an approved driver education program — both classroom and behind-the-wheel components — before the Secretary of State will issue an Instruction Permit. The course must be taken through a state-approved provider (a public school program or licensed commercial driving school). Home schooling does not satisfy this requirement unless the provider holds SOS approval. After completing driver education, passing the knowledge and vision tests, and paying the application fee, the teen receives the Instruction Permit.

Illinois law (625 ILCS 5/11-709) prohibits continuous left-lane driving when not actively passing another vehicle. Slower-moving vehicles must keep right on multi-lane highways. Illinois State Police began targeting 'left lane campers' with active enforcement after 2016. The law applies on Illinois Interstates and state highways with two or more lanes in the same direction. A left-lane violation is a moving infraction. Illinois Tollway sections (Tri-State I-294, I-88, I-90) are included in the enforcement area.

Illinois enacted its comprehensive handheld ban (625 ILCS 5/12-610.2) effective July 1, 2014 — making it one of the earliest states to prohibit all handheld device use for all drivers, not just texting. At the time, most states had only texting bans. Illinois's 2014 law covered calls, texting, browsing, and any handheld device interaction. The under-19 total ban (including hands-free) went into effect at the same time. Illinois's early adoption is relevant to the knowledge test because the law's 2014 vintage means it predates many applicants' awareness of when such laws were enacted.
