1. You come to a place where a storm has dropped a power line across the road ahead. What should you do?
Show answer
Answer B: Stop well back, keep everyone away from it and report it to the police
A downed line may be live and can energize the ground around it, so keep well clear and let the utility or the police handle it.
-
2. You are already inside a roundabout when an emergency vehicle approaches with lights and siren. What should you do?
Show answer
Answer B: Continue to your exit, leave the roundabout, then pull over and stop
Stopping inside a roundabout blocks the circulating roadway, so you should exit first and then pull over clear of the intersection.

-
4. Should you drive with your hazard lights flashing while moving in fog?
Show answer
Answer A: No, they hide your turn signals and suggest you are stopped
Hazard lights on a moving vehicle tell other drivers you are stopped or disabled, and they cancel out your turn signals just when clarity matters most.
-

-
7. A high truck ahead of you hides the traffic signal as you approach the intersection. What should you do?
Show answer
Answer A: Drop back so you can see the signal and the truck's brake lights
Extra following distance restores your view of the signal, so you are reacting to the light yourself rather than copying the truck driver.
-
8. You are entering an angle parking space on your right. What should you do?
Show answer
Answer C: Stay a little left of the space, then turn in between the lines
Keeping a little left of the space gives the front wheels the room to turn in cleanly and leaves your car centered between the lines.
-
9. How many alcoholic drinks does it take to begin affecting driving ability?
Show answer
Answer C: Even one drink can affect it
A single drink can slow reactions and weaken judgment before you feel any change. Impairment starts long before a person feels drunk.
-
10. On a rural road, the driver of a slow farm tractor ahead of you signals a left turn even though there is no road or driveway in sight. What should you do?
Show answer
Answer B: Stay behind the tractor, because it may be turning into a field entrance
Farm equipment often turns into fields through gaps you cannot see, and it may swing wide to do so. Passing a vehicle that is signaling a left turn is a common cause of crashes.
-
11. Your power steering fails while you are driving. What happens and what should you do?
Show answer
Answer B: Steering becomes much harder but still works, so slow down and pull off the road
Without power assistance the steering still works, but it takes much more effort, especially at low speed. Keep both hands on the wheel and get off the road.
-
12. A truck passes you in heavy rain and its spray blanks out your windshield. What should you do?
Show answer
Answer B: Hold the wheel steady, ease off slightly and let the wipers clear it
The blackout lasts a second or two. Keeping your line and easing off is far safer than braking hard or steering blind toward the shoulder.
-
13. Your parking brake no longer holds the car on a slope. What should you do?
Show answer
Answer D: Have it repaired, and until then park only on level ground
A parking brake that will not hold is a defect to be fixed; avoiding grades in the meantime keeps the vehicle from rolling away.
-
14. Under Illinois law, is holding a phone and using its speakerphone considered hands-free driving?
Show answer
Answer C: No, holding the device while using the speaker is a violation
Illinois states that using a cellphone while holding the device and using the speakerphone is not hands-free and violates the law; hands-free or Bluetooth technology is permitted for drivers 19 and older.

16. A person using a wheelchair is waiting to cross at a corner ahead. How should you treat that person?
Show answer
Answer B: As a pedestrian with the right of way at the crossing
A wheelchair or a mobility scooter user has the rights of a pedestrian, so yield the whole crossing and wait until the crossing is finished.
-
17. What is the main limit of stability and traction control systems?
Show answer
Answer B: They cannot create grip that the tires and the road do not have
These systems manage the grip that exists. If you enter a curve too fast for the surface, no amount of electronics will hold the vehicle on the road.
-
18. You are traveling in the same direction as a funeral procession and want to get ahead of it. What should you not do?
Show answer
Answer B: Driving in between the vehicles of the procession
Most states prohibit driving into or through a funeral procession, and cutting into the line leaves the drivers behind with no lead vehicle to follow, so go around only where passing is permitted.
-
19. Your vehicle stalls on a railroad crossing and will not restart. What should you do first?
Show answer
Answer A: Get everyone out and away from the tracks immediately
Everyone must leave the vehicle and move well clear of the tracks at once, walking toward the train at an angle so that debris from an impact travels away from you.
-
20. Freeway traffic ahead of you has come to a stop. Besides braking early, how can you warn the drivers behind you?
Show answer
Answer B: By switching on the hazard lights for a few seconds
A short burst of hazard lights is a recognized way to tell following traffic that the queue ahead has stopped, and it carries much further back than brake lights. Some states restrict hazard lights on a moving vehicle, so use them only for the moment you are slowing.
-
21. You will leave your vehicle for several hours after dark. Where is the best place to park it?
Show answer
Answer D: In a well-lit spot with people and cameras nearby
Light, passing people and cameras all discourage theft and make your own return to the vehicle safer.
-
22. You notice at night that one of your headlights has burned out. What should you do?
Show answer
Answer B: Get it replaced promptly, because other drivers may take you for a motorcycle
A single light makes your vehicle look narrower and further away, so other drivers misjudge you, and one light is also illegal.
-
23. You stop at the curb on a busy street to let passengers out. What should you tell them?
Show answer
Answer A: To get out on the curb side, away from traffic
Passengers should always leave on the side away from moving traffic, which keeps both them and the door out of the travel lane.
-
24. A driver passes this sign and the signal beyond it is already showing green. What is the safest response?
Show answer
Answer C: Ease off the accelerator and be ready to stop, because an indication that has been showing for a while is about to change
A signal that has been displaying the same indication for some time is close to changing, so arriving at a controlled speed with the brake covered is safer than accelerating to beat it.
-
25. You are driving slower than the general flow on a multilane highway. Which lane should you use?
Show answer
Answer D: The right lane, keeping the left lanes free for faster traffic and passing
Slower traffic must keep right so that faster vehicles and overtaking traffic can use the left lanes without weaving between lanes.
-
26. The circular sign shape is reserved for which warning?
Show answer
Answer C: Advance warning of a highway-rail grade crossing
A round yellow sign with a black X and the letters RR is the grade crossing advance warning sign, and the circular outline is used for no other message.
-
27. How does a NO OUTLET sign differ from a DEAD END sign?
Show answer
Answer B: It warns that a whole group of streets has no way out
No Outlet is posted where the road leads into a network of streets from which there is no through route, while Dead End refers to the single street itself.
-

Show answer
Answer B: 5 nanograms per milliliter of whole blood, or 10 nanograms per milliliter of urine
Illinois sets a per se cannabis DUI threshold of 5 nanograms per milliliter of THC in whole blood, or 10 nanograms per milliliter in urine.
-
29. Compared with dry pavement, how much room does a vehicle need to stop on packed snow?
Show answer
Answer D: Several times as much
Grip on packed snow is a fraction of that on dry pavement, so stopping distance grows several times over. Antilock brakes help you steer, not stop shorter.
-
30. How often must an Illinois driver take the written exam?
Show answer
Answer B: Every eight years, except for a driver with no traffic convictions
Illinois requires the written exam every eight years, with an exception for drivers who have no traffic convictions on their record.
-
31. Why should your thumbs rest along the rim rather than hook inside the spokes?
Show answer
Answer D: A jolt can spin the wheel and injure hooked thumbs
A pothole or a dropped wheel can snap the wheel round violently, and thumbs hooked through the spokes are trapped when it happens.
-
32. The queue for an exit ramp has backed up into the right lane of the highway. What should you do if you want that exit?
Show answer
Answer B: Join the back of the queue in the lane instead of cutting in later
Passing a queue and forcing in at the front stops the whole line, and using the shoulder puts you where broken-down vehicles are expected to be.
-
33. In heavy fog at night on a rural two-lane road, which marking best helps a driver hold position?
Show answer
Answer C: The solid white line along the right edge
Steering by the right edge line keeps a driver clear of oncoming traffic, while watching the center line tends to pull the vehicle toward it.
-
34. A driver on the street this sign governs is preparing to turn left at the next corner. Which lane should the vehicle be in beforehand?
Show answer
Answer A: The lane closest to the left curb
All the traffic here runs the same way, so nothing is coming toward the driver and the turn is taken from the extreme left lane rather than from beside the middle of the roadway.
-
35. You must slow suddenly on a highway and a vehicle is following close behind you. What helps prevent a rear-end collision?
Show answer
Answer D: Tapping the brake pedal early so your brake lights flash a warning
Early brake light flashes give the driver behind more time to react, and slowing gradually instead of suddenly reduces the chance of being struck.
