How many questions are on the Illinois motorcycle knowledge test?

The Illinois Secretary of State (SOS) motorcycle knowledge test has 15 multiple-choice questions. You must answer at least 12 correctly to pass, which is a score of 80%. Questions are based on the Illinois Motorcycle Operator Manual.

Can I skip the written test and road test for an Illinois motorcycle license?

Yes, if you are 18 or older. Adults 18 and older who successfully complete an IDOT (Illinois Department of Transportation) approved Motorcycle Rider Education Course receive a completion card that allows them to waive BOTH the written knowledge test AND the on-cycle riding skills test at the SOS. The completion card is valid for 1 year. Riders under 18 must complete the IDOT course as a mandatory requirement but still must take the riding skills test.

What is the difference between a Class M and Class L motorcycle license in Illinois?

A Class M license authorizes operation of any motorcycle or motor-driven cycle with engine displacement over 150cc — this is the standard motorcycle license. A Class L license covers only motor-driven cycles (mopeds, small scooters) with engine displacement less than 150cc. A Class M license covers both types; a Class L license does not authorize riding larger motorcycles.

Is eye protection required for Illinois motorcycle riders?

Yes — with one exception. Illinois law requires motorcycle operators (and passengers) to wear eye protection (goggles, glasses, or a face shield) if the motorcycle is not equipped with a windshield. If the motorcycle has a windshield that provides adequate eye protection, the eye protection requirement does not apply. This is a specific Illinois law that applies regardless of whether helmets are worn.

What is the BAC limit for motorcycle riders in Illinois?

For riders 21 and older, the DUI limit is 0.08% BAC. For riders under 21, Illinois has an absolute Zero Tolerance law — any traceable amount of alcohol or drugs in the rider's system results in a statutory summary suspension of driving privileges (minimum 6 months for a first violation). Illinois DUI also covers impairment by any drug, including legal recreational cannabis and prescription medications that impair riding ability.

Licensing roadmap

How to prepare for motorcycle licensing in Illinois

Use this study roadmap, then confirm the requirements for your age and engine size with the Illinois Secretary of State.

Choose the correct class

Illinois adds a motorcycle classification to your licence rather than issuing a separate one. Class L covers a motor-driven cycle under 150cc; Class M covers any motorcycle of 150cc or greater. Applicants must be at least 16.

Study and pass the required tests

Study the Illinois Motorcycle Operator Manual and the Rules of the Road, then pass the vision screening, the motorcycle written exam and the on-cycle riding test through the Secretary of State.

Consider the free rider course

The Illinois Cycle Rider Safety Training Program is free to residents 16 and older. Graduates aged 18 and over can use the completion card in place of both the written and riding exams. Applicants under 18 are required to complete the Basic Rider Course.

Frequently asked questions

Illinois motorcycle test FAQs

Is this an official Illinois motorcycle test?

No. These are independent educational practice tests and are not affiliated with, sponsored by, or endorsed by the Illinois Secretary of State.

Does Illinois require motorcycle riders to wear a helmet?

No. Illinois is one of only three states with no helmet law at any age, alongside Iowa and New Hampshire. A helmet remains strongly recommended, because head injury is the leading cause of motorcycle fatalities, but it is not legally required.

What protective gear does Illinois actually require?

Eye protection. Under 625 ILCS 5/11-1404 every operator and passenger must be protected by glasses, goggles or a transparent shield, unless the motorcycle has a windscreen of sufficient height. Ordinary sunglasses qualify only if they are shatter-resistant.

What is the difference between a Class L and a Class M licence?

Class L covers a motor-driven cycle with an engine under 150cc. Class M covers any motorcycle of 150cc or greater. Both are added to an existing Illinois driver's licence rather than issued separately.

Can a rider course replace the written and riding tests?

Yes, for graduates aged 18 and over. Completing an approved Illinois Cycle Rider Safety Training Program course lets you skip both exams at the Secretary of State. The courses are free to Illinois residents 16 and older.

Is lane splitting legal in Illinois?

No. Riding between lanes of traffic is prohibited in Illinois. Two motorcycles may share a single lane side by side, but a rider may not split lanes to pass stopped or slow traffic.

Frequently Asked Questions

Illinois Motorcycle Test — Common Questions

Everything you need to know before taking your Illinois Secretary of State motorcycle knowledge test (Class M / Class L).

The Illinois SOS motorcycle knowledge test has 15 multiple-choice questions. You need to answer at least 12 correctly (80%) to pass. Questions are drawn from the Illinois Motorcycle Operator Manual and cover road rules, safety practices, and Illinois-specific motorcycle laws.

No. Illinois has no mandatory motorcycle helmet law for riders or passengers of any age. The state's helmet law was declared unconstitutional in 1969 and has never been replaced. Illinois is one of only a few states with no helmet requirement. However, helmets are strongly recommended — head trauma is the leading cause of motorcycle fatality, and NHTSA data shows unhelmeted riders are ~40% more likely to sustain a fatal head injury.

Yes, if you are 18 or older. Adults who successfully complete an IDOT-approved Motorcycle Rider Education Course receive a completion card that waives both the written knowledge test and the riding skills test at the SOS. The card is valid for 1 year. For riders under 18, the IDOT course is mandatory — not optional. Illinois also offers free Cycle Rider Safety Training Program (CRSTP) courses throughout the state.

Class M authorizes operation of any motorcycle or motor-driven cycle with engine displacement over 150cc — the standard full motorcycle license. Class L covers only motor-driven cycles (mopeds, small scooters) with engine displacement under 150cc. A Class M license covers both types; a Class L license does not allow riding larger motorcycles.

No. Lane splitting is illegal in Illinois. The Illinois Motorcycle Operator Manual specifically states that a motorcycle should never be ridden between lanes of traffic, even if there appears to be room. Note: two motorcycles may legally ride side-by-side within a single lane (lane sharing) — that is different from lane splitting. Lane splitting can significantly affect fault in any crash under Illinois's modified comparative fault rules.

Illinois requires minimum coverage of $25,000 per person / $50,000 per accident / $20,000 property damage (25/50/20). Importantly, Illinois also requires uninsured/underinsured motorist (UM/UIM) coverage as part of the minimum policy — protecting you if struck by an uninsured driver. Insurance must be maintained as long as the motorcycle is registered and operated.

Illinois motorcycle permit holders are restricted to: daylight hours only, no passengers, no interstate highways or tollways, and must be supervised by a licensed motorcycle operator aged 21+ with at least 1 year of riding experience. Permit validity: 12 months for riders 18+; 24 months for riders under 18.

Yes — unless the motorcycle has a windshield. Illinois law requires all motorcycle operators (and passengers) to wear eye protection (goggles, glasses, or face shield) if the motorcycle is not equipped with a windshield. Even though helmets are not required, eye protection is a separate legal requirement. A face shield on a helmet satisfies this requirement.

For riders 21 and older: 0.08% BAC (DUI). For riders under 21: Illinois has absolute Zero Tolerance — any traceable amount of alcohol or drugs triggers a statutory summary suspension of at least 6 months for a first violation. Illinois DUI also covers impairment by legal recreational cannabis and prescription medications. Illinois DUI applies to any substance that renders the rider incapable of driving safely.

The Illinois test covers 8 main areas: motorcycle controls and operation (Class M/L distinctions, T-CLOCS, SEE strategy), lane positioning (lane splitting illegal, lane sharing legal, permit restrictions), road signs and signals, helmet and safety gear (no helmet law, eye protection required without windshield), Illinois traffic laws (25/50/20 + UM/UIM insurance, Zero Tolerance, IDOT course benefits), hazardous conditions (Illinois winters, railroad crossings, spring road conditions), passengers and cargo, and rider fitness and responsibility.

This practice test uses 200+ questions based on the 2026 Illinois Motorcycle Operator Manual and Illinois-specific laws. The key difference: this test shows a detailed explanation after every answer — the real SOS test does not. The real test has 15 questions on an SOS computer terminal. This is a study tool — not an official SOS or IDOT product — but it covers every topic and Illinois-specific law that appears on the real exam.

Yes — all 200+ practice questions are fully mobile-friendly. The interactive quiz works on any smartphone, tablet, or desktop browser with no app download and no sign-up required. Just tap an answer to get instant feedback and a detailed explanation of the correct answer and relevant Illinois law.
