Illinois doesn't publish its knowledge-test length and pass score on an official page we could confirm, so we don't state numbers here. The questions in this quiz are written in the style of Illinois's knowledge test, and Illinois's official driver handbook (linked below) is the source to study from.
Pick an answer on each question to see whether you got it right, with an explanation.
This is a short sample — DriveDrill has 200+ Illinois questions
and full-length mock exams in the app.
Q1. The Illinois school zone speed limit, on school days between 6:30 a.m. and 4 p.m. when children are present and signs are posted, is:
A 30 mph
B 15 mph
C 25 mph
D 20 mph
Outside those hours, or with no children present, the ordinary posted limit applies.
Q2. A police officer is directing traffic at an intersection where the light is green. You should:
A Follow the signal because it is automatic
B Stop and wait for the officer to leave
C Follow the officer's directions even if they contradict the signal
D Choose whichever is safer
Directions from an officer or flagger override signs and signals every time.
Q3. A steady yellow traffic light means:
A Speed up to clear the intersection
B Stop and wait for a green arrow
C The light is about to turn red — stop if you can do so safely
D The light is about to turn green
Yellow is the warning that red is next. Stop if you can do it safely; if you are already so close that stopping would be abrupt or unsafe, continue through with care.
Q4. After a school bus turns off its red lights, you should still:
A Pass on the right
B Sound your horn to clear children
C Watch for children who may run into the road
D Accelerate to make up time
Children are unpredictable right after they get off a bus. Move off slowly and keep scanning both sides.
Q5. The minimum age for an Illinois instruction permit is:
A 16
B 14
C 15, with enrollment in an approved driver education course
D 17
Applicants aged 15 to 17 must be enrolled in an approved driver education course and hold the permit for at least nine months.
Q6. In Illinois, if an adult in the front seat is not wearing a seat belt:
A An officer may ticket you only after stopping you for something else
B An officer may stop you for the seat belt violation alone
C Seat belts are recommended but not required for adults
D Only the driver can be ticketed, never a passenger
This is a primary enforcement state: no other violation is needed. The belt is also the single most effective thing in the car for surviving a crash.
Q7. The recommended hand position on the steering wheel is:
A One hand on the gearshift
B Both hands on the wheel, at about 9 and 3 o'clock or lower
C One hand at 12 o'clock
D One hand at the very bottom of the wheel
States teach 9 and 3, 8 and 4, or lower still. Each gives good control and keeps your arms out of the airbag's path; 10 and 2 puts them where it deploys.
Q8. An Illinois driver under 18 may not drive between:
A There is no night restriction
B 10 p.m. and 6 a.m. Sunday through Thursday, and 11 p.m. to 6 a.m. Friday and Saturday
C Midnight and 5 a.m. every night
D 11 p.m. and 6 a.m. every night
The curfew starts an hour later on Friday and Saturday. Exceptions cover work, school activities and emergencies, and local curfews may be stricter.
Q9. A prescription medicine that makes you drowsy:
A Can make driving illegal and unsafe, just like alcohol
B Is safe if you take less than prescribed
C Is always safe because a doctor prescribed it
D Only matters for commercial drivers
Impaired driving laws cover any drug, prescribed or not. Read the label and do not drive when it warns you about machinery.
Q10. A standard drink of beer, wine and distilled spirits:
A Only matter for drivers under 21
B Differ so much that beer is always safest
C Cannot be compared
D All contain about the same amount of alcohol
A 12 oz beer, a 5 oz glass of wine and 1.5 oz of spirits each contain roughly the same alcohol, which is why counting drinks does not make you safe to drive.
