Illinois Permit Practice Test 2
20 new questions · no repeats from Test 1 · Updated July 12, 2026
A fresh 20 — no overlap with Test 1 — weighted toward the rules-of-the-road and safety questions people miss most. The real Illinois exam is 35 questions at 80% to pass — that 80% bar ties Illinois with 35 other states at #7 strictest of the 50 states.
Answer each question to see the explanation. Your score is tallied against the real passing bar at the end.
1. While operating a commercial motor vehicle, a driver is considered under the influence at a BAC of:
Show answer & explanation
Correct answer: 0.04 or more
The limit for a driver operating a commercial motor vehicle is stricter: 0.04 or more BAC, half the 0.08 limit for regular driving.
2. Besides passing the tests, what does a 15-year-old need to get an instruction permit?
Show answer & explanation
Correct answer: Consent of a parent or legal guardian
An applicant under 18 must have a parent or legal guardian sign for them, in addition to enrolling in driver education and passing the vision and written knowledge tests.
3. How close to a crosswalk at an intersection may you park?
Show answer & explanation
Correct answer: No closer than 20 feet
You may not stand or park within 20 feet of a crosswalk at an intersection; parking closer blocks the view between drivers and pedestrians.
4. You must be able to show proof of insurance:
Show answer & explanation
Correct answer: When a law-enforcement officer requests it and after a crash
Carry evidence of insurance in the vehicle. You must produce it on an officer’s request and exchange it after a crash.
5. When entering a roundabout, you must:
Show answer & explanation
Correct answer: Yield to traffic already circulating in the roundabout
Traffic in a roundabout has the right-of-way. Slow down as you approach, yield to vehicles already circulating (moving counterclockwise), and enter when there is a safe gap.
6. If your vehicle begins to hydroplane on a wet road, you should:
Show answer & explanation
Correct answer: Ease your foot off the accelerator and avoid braking hard or steering sharply
Hydroplaning means the tires are riding on a film of water. Ease off the gas and hold the wheel steady until the tires regain contact; hard braking or steering can throw you into a skid.
7. When following a motorcycle, you should:
Show answer & explanation
Correct answer: Allow a larger following distance than you would for a car
Motorcycles can stop quickly and may slow by downshifting without their brake light showing. Leave extra following distance so a sudden slowdown does not catch you out.
8. What does a flashing red traffic signal mean?
Show answer & explanation
Correct answer: Stop completely, then proceed when it is safe — the same as a stop sign
A flashing red light means the same thing as a stop sign: stop completely, yield to any traffic or pedestrians, and proceed only when it is safe.
9. What is the default speed limit in an urban district unless otherwise posted?
Show answer & explanation
Correct answer: 30 mph
In an urban district the statutory limit is 30 mph unless a different limit is posted. Watch for lower limits near schools, parks, and business areas.
10. When must you use your turn signal?
Show answer & explanation
Correct answer: Before every turn and lane change, and when moving right or left on the roadway
You must signal any time you turn, change lanes, or move right or left on the roadway, so other road users can anticipate your movement — even if you think no one is around.
11. In Illinois, a DUI charge can be based on:
Show answer & explanation
Correct answer: Alcohol, illegal drugs, cannabis, or even impairing prescription medication
DUI covers driving under the influence of alcohol, other drugs, intoxicating compounds, or cannabis — any substance that makes you incapable of driving safely.
12. How does an adult 18 or older apply for a first Illinois driver’s license?
Show answer & explanation
Correct answer: They may apply directly, without the driver-education requirement teens face
Adults 18 and older are not subject to the teen GDL pathway; they apply directly after passing the vision, written, and driving tests. The GDL age-and-education rules apply to new drivers under 18.
13. You may not stand or park within 30 feet of:
Show answer & explanation
Correct answer: A stop sign, yield sign, or traffic signal at the side of the road
Parking is prohibited within 30 feet of the approach to any flashing signal, stop sign, yield sign, or traffic control signal located at the side of a roadway, because a parked vehicle would hide the sign from other drivers.
14. Driving without insurance and causing bodily harm to another person is:
Show answer & explanation
Correct answer: A separate, more serious offense than simply driving uninsured
Illinois defines "operation of an uninsured motor vehicle causing bodily harm" as its own, more serious offense, with heavier penalties than ordinary uninsured driving.
15. In which direction does traffic travel around a modern roundabout in Illinois?
Show answer & explanation
Correct answer: Counterclockwise, keeping to the right of the central island
Traffic moves counterclockwise around the central island, so you always keep to the right of it. Never stop in a roundabout except to avoid a collision, and signal before exiting.
16. On snow or ice, the safest way to steer, brake, and accelerate is to:
Show answer & explanation
Correct answer: Make every input slow and gentle
On slick surfaces, sudden steering, braking, or acceleration breaks traction. Smooth, gentle inputs keep the tires gripping.
17. A motorcyclist may move to a different position within the lane in order to:
Show answer & explanation
Correct answer: Avoid road hazards, improve visibility, or be seen by other drivers
Riders shift within their lane to dodge potholes and debris, stay out of blind spots, and be more visible. Do not read a lane-position change as an invitation to share the lane.
18. What does a flashing yellow traffic signal mean?
Show answer & explanation
Correct answer: Slow down and proceed with caution
A flashing yellow light means slow down and proceed with caution. It does not require you to stop, but you must be alert for cross traffic and pedestrians.
19. What is the speed limit when driving in an alley?
Show answer & explanation
Correct answer: 15 mph
The speed limit in an alley is 15 mph. Alleys are narrow, and pedestrians, children, and vehicles may enter with little warning.
20. Your turn signals are not working. How should you signal a left turn?
Show answer & explanation
Correct answer: Extend your left arm straight out the window
With inoperative signals, use hand signals: left arm straight out for a left turn, arm up for a right turn, and arm down for stopping or slowing.
