1. During the reversing part of a three-point turn, where should you be looking?
Show answer
Answer C: Over your shoulder through the rear window, glancing both ways
You look through the rear window in the direction the car is moving, checking both ways for traffic and people, because mirrors and cameras leave blind areas.
-
2. A motorcycle ahead of you is weaving slightly as it crosses a stretch of grooved pavement. What should you do?
Show answer
Answer D: Give the rider extra room until the surface improves
Grooves, metal plates and loose material affect a motorcycle far more than a car, so back off and let the rider deal with the surface.
-
3. 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.
-
4. A driver sees this sign on a quiet road with no other traffic in either direction. What is the correct response?
Show answer
Answer C: Slow down, look and listen for a train, and be ready to stop
The sign gives advance notice of a highway-rail grade crossing, so the driver reduces speed, checks both directions along the tracks and keeps enough room to stop short of the rails.
-
5. May you use a relative's accessible parking placard to park in a marked accessible space?
Show answer
Answer D: No, only when the placard holder is being transported in the vehicle
A placard belongs to the person, not to the car, so it is valid only when that person is being transported; using it otherwise takes a space from someone who needs it.
-
6. A child seat was in the car during a moderate crash. What should be done with it?
Show answer
Answer A: Replace it, because a seat that has been through a crash may be weakened
Crash forces can damage a seat in ways you cannot see, so a seat involved in anything but the mildest crash is replaced.
-
7. What is the maximum fine a court may impose for a first DUI conviction in Illinois when the driver's BAC was below .16?
Show answer
Answer D: $2,500
A first DUI conviction in Illinois carries a maximum fine of $2,500, along with up to one year of imprisonment.
-
8. On a narrow residential street, why does parking tight against the curb matter so much?
Show answer
Answer C: Because fire trucks and ambulances need the width to get through
Cars parked even a foot out from the curb on both sides can narrow a street until a fire truck or ambulance cannot pass.
-
9. At a freeway exit ramp, this sign normally backs up which other regulatory sign posted nearer to the ramp terminal?
Show answer
Answer D: The sign that forbids entering that roadway at all
The two work as a pair at ramp terminals: one keeps drivers from turning in, and this one sits farther along to catch a driver who has already entered.
-
10. A left-turn bay opens ahead of the intersection with a solid white line beside it. Where should you enter the bay?
Show answer
Answer C: At the opening before the solid line begins
The solid line marks where lane changes are no longer intended, so you move into the turn bay at its opening rather than cutting across the line later.
-
11. A driver is tailgating you. Why is it a bad idea to tap or stab the brakes to warn them?
Show answer
Answer C: Because it cuts the little space they have and can cause a crash
Brake checking removes the small margin the tailgater has left and can provoke a collision; add space in front of you instead and let them pass.
-
12. Why can an oncoming vehicle that looks comfortably far away leave you far less room than you expect?
Show answer
Answer D: You and that vehicle close the gap at the sum of both your speeds
Two vehicles approaching at 55 mph each close the distance between them at about 110 mph, so the gap disappears in half the time you would expect.
-
13. You have parked a manual transmission car facing downhill. Which gear should you leave it in?
Show answer
Answer D: Reverse, along with the parking brake set firmly
Facing downhill the car would roll forward, so reverse gear opposes that movement while the parking brake and turned wheels back it up.
-
14. You are parking on a hill where there is no curb, whether facing up or down. Which way should the front wheels point?
Show answer
Answer B: Toward the shoulder, so the vehicle would roll away from the traffic lanes
With no curb to stop the vehicle, the wheels are turned toward the edge of the road so that a runaway vehicle leaves the roadway instead of entering it.
-
15. You have a green light at a school crossing, but the crossing guard steps out and holds up a stop sign toward you. What must you do?
Show answer
Answer A: Stop, because the crossing guard controls this crossing and outranks the signal
Directions from a crossing guard or a police officer take priority over signals and signs.
-
16. Why is it useful to watch the vehicle two or three places ahead of you?
Show answer
Answer C: You get an earlier warning of slowing traffic than brake lights give
Trouble travels back through a line of traffic, so seeing it start several vehicles ahead gives you a head start on braking.
-
17. Another vehicle is passing you on a two-lane road. What should you do with your speed?
Show answer
Answer A: Hold your speed or ease off slightly to shorten the pass
Speeding up strands the passing driver in the oncoming lane, while a steady speed or a slight lift lets the pass finish quickly and safely.
-
18. For how long after an Illinois DUI conviction must a driver typically carry high-risk (SR-22) auto insurance?
Show answer
Answer C: Three years
A DUI conviction in Illinois typically requires the driver to carry high-risk auto insurance for three years.
-
19. Trees block the view along the tracks as a driver approaches this sign. What approach speed is correct?
Show answer
Answer B: Slow enough to stop before the nearest rail once a train comes into view
Where the view along the track is obstructed, the only safe speed is one that still leaves stopping distance after a train first becomes visible.
-
20. Unless otherwise posted, what is the Illinois speed limit on interstates and tollways?
Show answer
Answer C: 70 miles per hour
Illinois sets 70 miles per hour on interstates and tollways, 65 on four-lane highways and 55 on other highways and rural areas unless otherwise posted.
-
21. On a highway with mileage-based exit numbering, you have just passed exit 42 and are looking for exit 55. About how far is it?
Show answer
Answer B: Thirteen miles
With mileage-based numbering each exit takes the number of the nearest milepost, so subtracting one exit number from another gives the distance in miles.
-
22. In a normal signal cycle, what comes after a steady red indication?
Show answer
Answer A: A green indication that starts the next movement
Yellow is a warning that a movement is ending, so it never precedes a green; a red is followed by a green or a green arrow.
-
23. A freeway sign shows a minimum speed limit. What does it require?
Show answer
Answer B: That you keep up with it unless conditions make that unsafe
A minimum speed limit keeps very slow vehicles off the highway, but weather, traffic or a mechanical problem may make a lower speed necessary and lawful.
-
24. Can a driver be charged with impaired driving after taking a legal over the counter medicine?
Show answer
Answer C: Yes, if the medicine impairs the ability to drive safely
Impaired driving laws cover any substance that affects driving, including cold remedies, allergy pills and sleep aids sold without a prescription.
-
25. You have strapped luggage to the roof rack for a long trip. What should you expect?
Show answer
Answer D: A higher center of gravity, so take the curves and lane changes gently
Weight on the roof raises the center of gravity and makes the vehicle lean and respond more slowly to steering.
-
26. What is the safest way to leave a perpendicular parking space in a busy lot?
Show answer
Answer B: Back out slowly, checking both ways and yielding
Backing out gives you the poorest view of any maneuver, so it must be done slowly, with checks in both directions and with yielding to whoever is already there.
-
27. A pedestrian signal changes to a flashing upraised hand. What does that indication mean?
Show answer
Answer C: Do not start crossing, but finish a crossing already begun
The flashing upraised hand is the pedestrian change interval: nobody may start to cross, but a pedestrian already in the crosswalk may continue to the far side or to a median.
-
28. A strong wind is blowing across an open stretch of road. Besides the gusts, what else should you watch for?
Show answer
Answer A: Branches, dust and loose objects blown into your path
High wind strips branches, litter and dust onto the roadway and can push other vehicles out of their lane, so scan much further ahead than usual.
-
29. A driver in the left lane of a freeway realizes only when level with this sign that the ramp beside it is the one they need. What is the correct action?
Show answer
Answer A: Carry on to the next interchange and turn back from there
There is no safe way back to a ramp once it has been reached from the wrong lane, so the driver keeps going to the next interchange, where the ramps are built for that movement.
-
30. You have entered a work zone where crews are working close to the open lane. What should you do?
Show answer
Answer A: Slow down and be ready for workers and machines
Workers and equipment cross the open lane without warning in a work zone, so reduced speed and attention on the road ahead are what keep them safe.
-
31. A sign at the start of an exit ramp shows a speed much lower than the highway limit. What does it apply to?
Show answer
Answer C: The curve of the ramp itself, once you have left the highway
The ramp speed is set by the sharpness of the ramp curve, so you slow to it inside the deceleration lane rather than out on the highway.
-
32. You hold steady pressure on the brake pedal for the whole of a long descent. What is likely to happen?
Show answer
Answer B: The brakes overheat and fade, so they slow you less and less
Continuous braking heats the brakes until they fade and lose effectiveness; use a lower gear and short, firm applications instead.
-
33. You stop behind another vehicle at a traffic light. How much space should you leave?
Show answer
Answer D: Enough to see where its rear tires touch the pavement
Seeing the rear tires on the road leaves room to steer around the vehicle if it stalls, and gives a cushion if you are struck from behind.
-
34. Which practice matches current child passenger safety guidance?
Show answer
Answer D: Keep a child rear facing until the top height or weight limit of the seat is reached
A rear facing seat spreads crash forces across the child's whole back, so it should be used as long as the seat allows, and never in front of an active passenger air bag.
-
35. How should a long trip be broken up to keep the driver alert?
Show answer
Answer D: Stop for a break every couple of hours and share out the driving
Regular breaks and a change of driver are the only reliable answers to fatigue; caffeine only postpones it.
