1. What does a green arrow lane signal over a highway lane tell a driver?
- The lane may be used without obeying any other sign or signal
- The lane is closed and must be left immediately
- The lane may be used only by emergency vehicles
- The lane may be used, but all other signs and signals must still be obeyed
Show answer
The lane may be used, but all other signs and signals must still be obeyed. Lane signals are special lights over each lane on highways and expressways, used most often to change the flow of traffic during certain hours. A green arrow indicates the lane may be used, but all other signs and signals must be obeyed. A red X means never drive in the lane, and a yellow X means the signal is about to change to red.

2. After legally changing your name, how soon must you apply for a corrected Illinois driver's license or ID card?
- Within 10 days of the name change
- Within 30 days of the name change
- Within 90 days of the name change
- Only when the current card expires
Show answer
Within 30 days of the name change. After a legal name change, apply for a corrected driver’s license or ID card within 30 days. Provide documentation linking the new name to the name on the current card and on file with the Secretary of State. Address changes have a separate 10-day notification deadline. Consider "Within 10 days of the name change": The ten day figure belongs to address change notices, not name corrections.
3. How do newer brakes compare with older, worn brakes in stopping a vehicle?
- Older brakes stop a vehicle more quickly
- Brake age makes no difference
- Brake age matters only in winter
- Newer brakes stop a vehicle more quickly
Show answer
Newer brakes stop a vehicle more quickly. When deciding your speed, the Illinois manual says to consider the condition of the brakes. It states that newer brakes stop a vehicle more quickly than older, worn brakes. Because worn brakes lengthen stopping distance, drivers with older brakes should leave extra room. The statement applies year round, not only in winter, and brake condition clearly matters. Check the condition of your brakes regularly and leave extra space when they are worn.

4. Who files the SR-22 certificate of insurance with the Secretary of State in Illinois?
- The driver, by mail with a court order
- The insurance company, filing directly
- The police department after each crash
- The vehicle dealer at purchase time
Show answer
The insurance company, filing directly. The insurance company files the SR-22 directly with the Secretary of State. Proof of financial responsibility can also include a bond or deposit of securities. The Secretary of State monitors insurance coverage for the period specified by law. Against "The driver, by mail with a court order", note this: Drivers do not mail in the certificate. Compare "The police department after each crash" next: The insurance company files the SR-22 directly with the Secretary of State.
5. Why does cancellation of an Illinois driver's license or permit occur?
- As punishment for a third traffic conviction
- Because of an error or defect in the license, or because the holder is no longer entitled to it
- Whenever a driver moves to a new address
- After any crash involving property damage
Show answer
Because of an error or defect in the license, or because the holder is no longer entitled to it. Cancellation formally terminates driving privileges because of an error or defect in the license or because the holder is no longer entitled to it. Listed reasons include medical unfitness, re-examination problems, fraudulent applications, and ineligibility. Reapplication is allowed only after the cancellation terms have been met. Against "As punishment for a third traffic conviction", note this: The manual defines cancellation by an error or defect in the license or the holder no longer being entitled to it.
6. When a vehicle is sold in Illinois, what happens to its license plates?
- They stay on the vehicle for the buyer to use
- They must be left with the Secretary of State office
- The seller removes and keeps them; plates remain with the owner, not the vehicle
- The buyer keeps the front plate and the seller the rear
Show answer
The seller removes and keeps them; plates remain with the owner, not the vehicle. When a vehicle is sold, the seller should remove and keep the license plates. In Illinois, plates remain with the owner, not the vehicle. The option "They stay on the vehicle for the buyer to use" should be set aside: Buyers may not use plates registered to the seller. "They must be left with the Secretary of State office" loses out as well: Plates are kept by the seller, not surrendered at the office.
7. In which situation may an Illinois driver lawfully leave the right half of the roadway?
- Whenever traffic ahead feels slow
- On a roadway divided into three marked lanes for traffic
- To reach a driveway on the left without yielding
- While following a vehicle at a close distance
Show answer
On a roadway divided into three marked lanes for traffic. You must drive on the right half of the roadway except in the situations listed in the manual, including on a roadway divided into three marked lanes for traffic. Other listed exceptions include passing, going around a blockage after yielding to oncoming traffic, and crossing the center line to turn left into or from a driveway. "Whenever traffic ahead feels slow" is a distractor here: Impatience grants no exception to right half driving.

8. Which students must still pass a DMV administered driving exam despite passing a driver education road test?
- Students whose birthdays fall on certain spot-check dates
- Students earning a combined grade of A in driver education
- Students holding a Cooperative Driver Testing Certificate
- Students who completed fifty hours of practice driving
Show answer
Students whose birthdays fall on certain spot-check dates. Even after passing an instructor administered road test, students whose birthdays fall on certain spot-check dates must pass a driving exam administered at a DMV before licensing. Strong classroom grades support exam exemption through cooperative testing rather than triggering a retest, the certificate itself documents the school based pass, and fifty practice hours qualify a teen for licensing without selecting anyone for spot checks. A birthday landing on a checked date overrides the school result.
9. What may a driver do when stopped by law enforcement at night in Illinois?
- Turn on the vehicle interior light
- Exit the vehicle to greet the officer
- Reach under the seat for documents before being asked
- Keep both hands hidden until identified
Show answer
Turn on the vehicle interior light. If stopped at night, it is acceptable to turn on the vehicle’s interior light. Stay in the vehicle with both hands visible on the steering wheel, do not exit unless asked, and follow the officer’s directions before retrieving documents stored under the seat or in the glove box. Against "Exit the vehicle to greet the officer", note this: Exiting uninvited can appear aggressive to an officer.

10. Your headlights fail suddenly while driving. What does the Illinois manual advise?
- Speed up to reach a lighted area
- Try the emergency flashers, parking lights, or turn signals, and pull off the road
- Turn off every light and coast
- Keep driving at normal speed until you see a service station
Show answer
Try the emergency flashers, parking lights, or turn signals, and pull off the road. For headlight failure, the manual says to try using your vehicle's emergency flashers, parking lights and/or turn signals, and pull off the road. If your lights begin to dim, drive to a service station or pull off the road and seek help. Speeding up or coasting without lights makes you hard for others to see. Stay calm, move off the road, and only then look for help.

11. What does the Illinois Tollway System ban during high winds?
- All passenger car travel
- Motorcycle travel only
- Fuel tanker travel only
- Hauling house trailers
Show answer
Hauling house trailers. The Illinois Tollway System bans hauling house trailers in high winds. The manual also advises reducing speed and making steering corrections when moving from protected to open areas or meeting large vehicles. Against "All passenger car travel", note this: The prohibition stated in the manual concerns hauling house trailers, not all passenger-car travel. Compare "Motorcycle travel only" next: Motorcycles are not the singled out vehicle class here.

12. When may an Illinois driver not enter an intersection or a marked crosswalk?
- When there is not enough space to allow passage of other vehicles or pedestrians
- Whenever the light is yellow
- Only during rush hour
- When a passenger asks the driver to wait
Show answer
When there is not enough space to allow passage of other vehicles or pedestrians. Do not enter an intersection or drive within a marked crosswalk unless there is enough space to allow passage of other vehicles or pedestrians. "Whenever the light is yellow" is a distractor here: Yellow governs signal change caution, not the space beyond the intersection. Another rival, "Only during rush hour", is wrong on its own terms: Blocked entries happen at any hour when far side space runs out.

13. Under the manual’s Scooters and Mopeds rule, what lights are required at night for a moped or motor-driven scooter, rather than a low-speed electric scooter?
- A headlight visible from at least 500 feet and a taillight visible from 100 to 600 feet
- A headlight visible from 100 feet only
- No lights below 25 mph
- A flashing blue light
Show answer
A headlight visible from at least 500 feet and a taillight visible from 100 to 600 feet. A scooter or moped driven at night must have a headlight visible from at least 500 feet and a rear taillight visible from at least 100-600 feet, as stated in the manual. Low-speed electric scooters have a separate lighting rule. The option "A headlight visible from 100 feet only" should be set aside: The stated headlight requirement is visibility from at least 500 feet, not 100 feet.
14. What does the Breath Alcohol Ignition Interlock Device report to the Secretary of State's office?
- Only monthly mileage
- Attempts to start the vehicle after drinking alcohol, or tampering with the device
- Tire pressure warnings
- Passenger seat belt status
Show answer
Attempts to start the vehicle after drinking alcohol, or tampering with the device. The Secretary of State’s office monitors the BAIID throughout the permit period. The device alerts the office if the driver attempts to start the vehicle after drinking alcohol or tampers with the device. Consider "Only monthly mileage": The manual identifies attempts to start after drinking and device tampering as alert events, not monthly mileage. Its rival "Tire pressure warnings" fails for a separate reason: The manual identifies attempts to start after drinking and device tampering as alert events, not tire pressure warnings.

15. What does Illinois law say about weaving from lane to lane to move faster than traffic flow?
- It is allowed below 30 mph
- It is allowed if signals are used
- It is unlawful
- It is allowed on Sundays
Show answer
It is unlawful. Weaving from lane to lane to move faster than the traffic flow is unlawful. The rule states no exception for speed, turn-signal use, or day of the week. The option "It is allowed below 30 mph" should be set aside: Speed does not convert weaving into lawful driving. "It is allowed if signals are used" loses out as well: Using turn signals does not make weaving to move faster than the traffic flow lawful.

16. When parking facing downhill on a street with curbing, which way should the front wheels be turned?
- Away from the curb
- Straight ahead
- Toward the curb
- Toward the center line
Show answer
Toward the curb. For downhill parking on a street with curbing, turn the front wheels toward the curb so the vehicle will roll toward it. When parking on a hill, put the gear selector in park and set the parking or emergency brake if necessary. Against "Away from the curb", note this: Away from the curb is the instruction for uphill parking with a curb, not downhill parking.

17. What may a local municipality do to a vehicle that interferes with a funeral procession through reckless driving?
- Issue a verbal warning only
- Impound the vehicle
- Fine the driver one dollar
- Escort the vehicle into the procession
Show answer
Impound the vehicle. Local municipalities may impound a vehicle that interferes with a funeral procession due to reckless driving. Motorists encountering a funeral procession must yield to all vehicles in the procession. Against "Issue a verbal warning only", note this: A warning alone ignores the impound authority cities hold here. Compare "Fine the driver one dollar" next: No token fine is stated for reckless procession interference.

18. What should you do before starting to drive in winter, according to the Illinois manual?
- Remove all snow and ice from the vehicle and clear all windows
- Clear only a small patch on the windshield
- Leave snow on the roof to insulate the vehicle
- Start driving and let the defroster clear the windshield
Show answer
Remove all snow and ice from the vehicle and clear all windows. The winter driving list says to remove all snow and ice from your vehicle, clear all windows, and not start driving until the windshield is defrosted and clear. It also says to have nonfreezing windshield washer liquid and make sure the headlights and taillights are visible. A partly cleared windshield limits your view and puts others at risk. Take the time to finish clearing the vehicle before you pull out.

19. Under the Illinois Contributing to a DUI rule, what is illegal?
- Lending a vehicle to a sober friend
- Riding as a passenger with a sober driver
- Allowing someone to drive your vehicle if you know that person is under the influence
- Parking near a bar
Show answer
Allowing someone to drive your vehicle if you know that person is under the influence. The manual says it is illegal to allow someone to drive your vehicle if you know that person is under the influence. A person convicted of providing alcohol to someone under age 21 may be fined, sentenced to jail, and have driving privileges suspended. Lending a car to a sober driver is not the offense. Providing alcohol to someone under age 21 can also bring fines, jail, and suspension.

20. Whose driving privileges will the Secretary of State immediately revoke?
- Anyone receiving a first parking ticket in a calendar year
- Anyone convicted of one ordinary speeding ticket
- Anyone who fails a vision screening once
- Anyone convicted of a moving violation that caused a crash resulting in the death of another person
Show answer
Anyone convicted of a moving violation that caused a crash resulting in the death of another person. The Secretary of State will immediately revoke the driving privileges of anyone convicted of a moving violation that caused a crash resulting in another person’s death. Revocation is an indefinite withdrawal of privileges; eligibility to reapply may begin after at least one year unless otherwise noted. Against "Anyone receiving a first parking ticket in a calendar year", note this: The stated immediate-revocation rule concerns a moving violation causing a fatal crash.
