Straight answers to the most common questions about passing the SOS motorcycle knowledge exam.
Illinois adds a motorcycle classification to your driver's license — Class L for a motor-driven cycle under 150cc, or Class M for any motorcycle. You must pass a separate motorcycle examination (a knowledge test and the Rider Skill Test) at a Secretary of State Driver Services facility.
The Illinois Motorcycle Operator Manual does not publish an official question count or passing score — it contains only four sample knowledge questions. Our practice test uses a 15-question, 12-to-pass (80%) format so you can prepare in an exam-style way. Study the whole manual rather than memorizing a fixed list.
No. A helmet is not required under Illinois law for riders or passengers of any age. The manual still strongly recommends one — helmeted riders are about three times more likely to survive a head injury, and head and neck injuries cause a majority of serious and fatal motorcyclist injuries.
Yes. Illinois required-equipment law states that both the driver and any passenger must be protected by glasses, goggles, or a transparent windshield. A shatter-resistant face shield protects your whole face; goggles protect only the eyes; eyeglasses or sunglasses alone are not adequate.
A Class L license covers any motor-driven cycle with less than 150cc displacement. A Class M license covers any motorcycle or motor-driven cycle (150cc and over). The correct piston displacement must appear on your license plate registration.
A motorcycle instruction permit lets you ride only during daylight hours and only under the direct supervision of a licensed motorcycle operator who is age 21 or older with at least one year of driving experience. Applicants under 18 may be issued a 24-month Class M instruction permit only after completing an approved driver education course and an IDOT Motorcycle Rider Education Course.
Yes. If you are age 16 or older, hold a valid Illinois driver's license, and successfully complete a motorcycle training course approved by the Illinois Department of Transportation (IDOT), you are not required to pass the written or driving examination at a Driver Services facility — you already passed a skills test at the end of the course.
An IDOT Motorcycle Rider Education Course completion card is valid for one year after the issue date. To use it in place of the tests, the card must be dated after January 1, 1993, and be presented with proper identification.
The knowledge test and the Rider Skill Test are given at Illinois Secretary of State Driver Services facilities. The Rider Skill Test is conducted in an off-street paved area about 30 feet by 75 feet, and an equipment check is done before the test begins.
The Rider Skill Test is an on-cycle test administered by the Secretary of State that measures vehicle-handling skills through four exercises — a cone weave with normal stop, a turn from a stop and U-turn, a quick stop, and an obstacle swerve. It checks your ability to accelerate, brake, turn, stop, and swerve safely.
Points are assessed for errors during the exercises. Obtaining 11 or more points is a failure. The test is also terminated if you fall or drop the motorcycle, commit an unsafe act such as raising the front wheel or losing control, or exceed a reasonable time limit. Stalling the engine four times during the test is an automatic failure.
Yes. Illinois law allows a motorcycle to proceed through a red light that fails to change to green within a reasonable period of time — not less than 120 seconds — provided you do so safely and yield to other traffic.
The Illinois Motorcycle Operator Manual recommends a minimum three-second following distance behind the vehicle ahead, and a larger cushion when the pavement is slippery, you cannot see past the vehicle ahead, or traffic is heavy.
Lane sharing is usually prohibited — automobiles and motorcycles each need a full lane to operate safely. Riding between rows of stopped or moving cars in the same lane leaves you vulnerable to opening doors, turning cars, and other surprises.
Yes. Illinois law requires the headlight to be on whenever the motorcycle is operated on streets and highways. Using the high beam during the day increases the chance that oncoming drivers will see you; use the low beam at night and in cloudy weather.
A moped may be operated with any current, valid driver's license of any classification, as long as it meets all four moped criteria — speed attainable in one mile between 20 and 30 mph, a motor of 2 brake horsepower or less, an engine displacement no greater than 50cc, and an automatic (no-shift) drive system. If it fails any criterion, it is a motor-driven cycle and a Class L is required.
Yes. If you are an out-of-state driver, you may ride during the period you are in Illinois, provided you hold a valid driver's license with the appropriate motorcycle classification from your home state or country.
Study the Illinois Motorcycle Operator Manual (DSD X 140), published by the Illinois Secretary of State. It contains the information needed for the motorcycle license exams. The manual also recommends reviewing the Illinois Rules of the Road booklet for general traffic-safety laws.

The Illinois Motorcycle Operator Manual does not publish a question count or passing score; it includes only 4 sample knowledge questions. The 15-question, 12-to-pass (80%) figure shown here is the format used for the motorcycle endorsement supplement; a full Class M applicant may also take a general-knowledge test.
