Sample Illinois DMV Written Exam Questions & Official Manual Citations (2026)

Below are 2 real sample questions from our Illinois dmv written exam bank. Every question in PassMyDMV cites the exact page and rule in the official Illinois manual so you understand the law behind every answer:

Sample Question 1 · Warning Sign Colors Official Illinois Manual · Chapter 11 · Page 70

What color are warning signs that alert drivers to potential hazards ahead?

  • A. Red and white
  • B. Green with white text
  • C. Orange with black letters
  • D. Yellow or yellow-green with black symbols Correct
Why D. Yellow or yellow-green with black symbols is correct: Yellow and yellow-green are the colors used for warning signs. These signs tell you of road conditions and dangers ahead. Yellow-green warning signs specifically alert you to pedestrian and bicycle crossings, playground areas, school bus stops, and school zones. Orange warning signs are used for construction and maintenance zones. When you see a yellow or yellow-green warning sign, you should slow down and use caution. [Manual: Roadway Signs — Colors of Signs, p. 70]
Manual excerpt (Official Illinois Manual · Chapter 11 · Page 70): “YELLOW is used for warning signs. These signs tell you of road conditions and dangers ahead. YELLOW-GREEN can also be used for warning signs. These signs alert you to pedestrian and bicycle crossings, playground areas, school bus stops, and school zones.”
Sample Question 2 · Red Sign Meaning Official Illinois Manual · Chapter 11 · Page 70

What do RED signs tell you to do?

  • A. They are regulatory signs that must be obeyed Correct
  • B. They provide directions to destinations
  • C. They indicate speed recommendations
  • D. They warn you of upcoming hazards
Why A. They are regulatory signs that must be obeyed is correct: RED signs are regulatory signs and must be obeyed. Red signs include STOP, YIELD, DO NOT ENTER, and WRONG WAY. Red signs control traffic and tell drivers what actions they must take. The red color itself is a standard traffic control color that signals mandatory compliance. Ignoring red signs is illegal and dangerous. [Manual: Roadway Signs — Colors of Signs, p. 70]
Manual excerpt (Official Illinois Manual · Chapter 11 · Page 70): “RED signs are regulatory signs and must be obeyed. They include STOP, YIELD, DO NOT ENTER, or WRONG WAY.”

What to Expect on the Illinois Written Exam

Illinois's permit test emphasizes practical traffic law knowledge and sign recognition equally. Expect questions on right-of-way rules, safe following distances, speed limits, parking regulations, and proper use of turn signals. The test covers proper responses to traffic control devices, lane positioning, and navigating intersections safely. You'll encounter questions about driving under the influence and the consequences of impaired driving. The sign identification section tests your ability to recognize warning signs, regulatory signs, and information signs by their shape and color—red octagon for stop, yellow diamond for warning, and white rectangle for regulatory signs. Chicago and major urban area questions might focus on managing heavy traffic and lane discipline, while rural questions emphasize open road safety and highway merging.

Car / Standard Driver License

Illinois's written permit test consists of 35 questions split into two sections: 20 on traffic laws and regulations (multiple-choice and true/false format) and 15 on traffic sign identification based on shape, color, and symbol. You must answer at least 28 questions correctly (80%) to pass. The test costs $20 and is administered in person at Illinois Secretary of State Driver Services facilities. You must be at least 15 years old to test. If you fail within 90 days, you can retake the test up to two more times, though there is typically a one-day waiting period and a reexamination fee for each retake.

Motorcycle Endorsement

Illinois's motorcycle endorsement test consists of 15 questions, and you need to answer at least 12 correctly (80%) to pass. The motorcycle license fee is $10. If you're under 18 and don't have a motorcycle rider course certificate, you must pass this knowledge test to qualify for the Class L endorsement.

Commercial Driver License (CDL)

Illinois's CDL permit test covers three main sections: General Knowledge (approximately 50 questions), Air Brakes (approximately 25 questions), and Combination Vehicles (approximately 25 questions). You must score at least 80% on each section to pass. The CDL issuance fee is $60 total, with additional endorsement fees depending on what type of commercial driving you'll perform.

Top Study Tips for Passing in Illinois

  • Download the free Illinois Rules of the Road handbook from www.ilsos.gov, available in English and Spanish, and study it thoroughly for the traffic law section.
  • Dedicate specific study time to road sign recognition—memorize sign shapes, colors, and their meanings, as this comprises half of your 35 questions.
  • Take free practice tests online that match the official format, especially ones that separate traffic laws from sign identification questions.
  • Visit the official Illinois SOS website to make an appointment for your test; walk-ins may not be accommodated at all facilities.
  • If you speak Spanish, Polish, Korean, Chinese, or Arabic, request testing in your preferred language when scheduling your appointment.
  • Remember that you have up to three attempts within 90 days; if you fail, study your weak areas carefully before your next try.
  • Study Chicago-specific driving scenarios if you live in or near the metropolitan area, as questions may reference major highways and urban traffic patterns.
