1. A white diamond symbol is painted in a highway lane. What does it identify?
Show answer
Answer C: A lane reserved for high-occupancy vehicles
The diamond symbol marks a preferential lane, most often one reserved for vehicles carrying a minimum number of occupants.
-
2. Some drivers believe they can multitask while driving. What does research show?
Show answer
Answer C: The brain switches rapidly between tasks and driving performance suffers
The brain does not truly do two attention-demanding tasks at once; it alternates between them, and the driving task gets less attention each time.
-
3. What is the first thing to do once your disabled vehicle is stopped on the shoulder?
Show answer
Answer A: Switch on the hazard warning lights so other drivers can see the vehicle
Hazard lights are the fastest way to make a stopped vehicle visible, and everything else can follow once traffic has been warned.
-
4. You are traveling beside a tractor-trailer and cannot see the truck driver's face in any of the truck's mirrors. What does that tell you?
Show answer
Answer A: The truck driver probably cannot see your vehicle
Large trucks have deep blind spots on all four sides, so if the driver's face is not visible in a mirror the driver has no view of you. Move ahead or drop back until you are out of that area.
-
5. A bicyclist ahead of you puts the left arm straight out to the side. What is being signaled?
Show answer
Answer B: A left turn or a move to the left
The left arm held straight out is the bicycle signal for a left turn, so hold back and give the rider room to cross toward the center.
-
6. The car ahead of you slows down for no reason that you can see. Should you pull out and pass?
Show answer
Answer B: No, find out why it is slowing before you commit to the other lane
A driver usually slows for something, such as a turn, a hazard or a pedestrian, and that something is often exactly where your pass would take you.
-
7. A notification appears on your smart watch while you are driving. What should you do?
Show answer
Answer B: Treat it as you would a phone and leave it
A watch screen demands the same eyes and the same attention as a phone, and a wrist is no safer a place to read a message than a dashboard.
-
8. A crossing guard steps into the roadway ahead of this sign with one hand raised. What must the driver do?
Show answer
Answer B: Stop and stay stopped until the guard waves traffic on
An adult guard is controlling traffic at that crossing, so the instruction given by that person governs and the driver waits to be released.
-
9. Your car has side curtain airbags. What should you avoid doing?
Show answer
Answer B: Resting your head against the window or the door pillar
A side airbag deploys from the pillar or roof rail, so a head leaning against that area is directly in its path.
-
10. On which approach is this sign normally installed?
Show answer
Answer C: On the road that ends, far enough ahead for the driver to slow down
The warning belongs on the approach that terminates, placed early enough that the driver can lose speed and choose a direction before reaching the junction.
-
11. A curb sign reads 2 Hour Parking, 8 AM to 6 PM, Monday to Saturday. When may you stay longer than two hours?
Show answer
Answer A: Outside those hours and on Sundays
A time limit applies only during the days and hours printed on the sign; outside them the ordinary parking rules apply.
-
12. You turn left onto a road that has a center two-way left-turn lane. In which lane should you be traveling once the turn is finished?
Show answer
Answer D: The first through lane to the right of the center turn lane
The shared center lane is only for turning movements, so even where a state lets you pause in it to merge you must end up in the first ordinary travel lane beside it.
-
13. A bicyclist is riding in the middle of a narrow travel lane ahead of you. What is the correct response?
Show answer
Answer D: Slow down and wait until you can pass with wide clearance, changing lanes if needed
A bicyclist has the same right to use the lane as a driver, and a narrow lane may not leave safe passing room, so wait for a gap that lets you move over and pass with a wide margin.
-
14. A loaded truck is coming up an entrance ramp as you approach in the right lane of the freeway. What is the most helpful action?
Show answer
Answer A: Adjust your speed to open a gap for it
A heavy vehicle accelerates slowly, so opening a gap or moving over costs you seconds and saves the truck driver from being forced to stop on the ramp.
-
15. How does alcohol typically affect a driver's vision?
Show answer
Answer D: It blurs vision, weakens night vision and narrows attention to the sides
Alcohol slows the eye muscles and the brain's processing of what is seen, degrading focus, night vision, depth perception and awareness of movement at the edges of the field of view.
-
16. You turn from asphalt onto a loose gravel road. What should you do about your speed?
Show answer
Answer D: Lower it, since grip is reduced and stopping takes longer
Loose gravel gives far less grip than pavement, so speed must come down for both steering and stopping.
-
17. Your steering suddenly feels light and unresponsive as you drive through standing water. What should you do first?
Show answer
Answer A: Ease off the accelerator and keep the steering wheel pointed straight
Those symptoms mean the tires are riding on a film of water, and gently lifting off the accelerator lets them settle back onto the pavement. Hard braking or sudden steering while hydroplaning can start a skid.
-
18. Reaching for a drink in the cup holder is which kind of distraction?
Show answer
Answer A: Manual and visual at the same time
Your hand leaves the wheel and your eyes flick down to find the cup, so a task that feels trivial takes away two of the three things driving needs.
-
19. A yellow diamond shows the two edges of the road pinching toward each other. What does it mean?
Show answer
Answer B: The pavement gets narrower but the lanes continue
The road narrows sign warns that the traveled way becomes tighter, leaving less room beside passing vehicles even though no lane is dropped.
-
20. What is the usual result of driving well above the flow of traffic on a typical trip?
Show answer
Answer B: Very little time saved, with much greater risk
Signals, traffic and short distances swallow the theoretical gain, while crash risk and crash severity both climb sharply with speed.
-
21. A vehicle is sitting in your blind spot and you need to change into that lane. What should you do?
Show answer
Answer B: Adjust your speed to open a clear gap, then check again and move over
Changing your speed either drops the other vehicle behind you or lets it move ahead, which turns the blind spot back into open space.
-
22. What can a loose or doubled up floor mat on the driver side cause?
Show answer
Answer A: It can slide forward and trap the accelerator pedal down
An unsecured mat, or a second mat laid over the first, can slip forward and hold the accelerator open. Use the mat clips and never stack mats.
-
23. An ambulance has just gone by and traffic starts to move again. Why should you wait a moment before pulling back out?
Show answer
Answer B: Another emergency vehicle may be following the first one
Emergency calls often bring several vehicles, so check that nothing else is coming before you rejoin the traffic lane.
-
24. Why would this sign be installed on an approach?
Show answer
Answer B: Because the signal cannot be seen from far enough back for a driver to react in time
Advance notice of a signal is used where a crest, a curve, trees or a building keep the signal heads out of view until a driver is already too close to stop comfortably.
-
25. An ambulance with lights and siren is coming toward you on an undivided two-lane road. What must you do?
Show answer
Answer A: Pull to the right edge and stop until it passes
On an undivided road, drivers in both directions clear the way, pulling to the right edge and stopping.
-
26. You are stopped in slow traffic and a motorcycle comes up between the lanes. What should you do?
Show answer
Answer D: Hold your position and avoid any sudden lane change
The danger to a rider between lanes comes from a vehicle moving sideways without warning, so staying predictable is what protects them.
-
27. How does the blood alcohol standard for a driver operating a commercial vehicle compare with the one for a car driver?
Show answer
Answer D: It is lower, set at 0.04
Commercial drivers are held to a stricter standard of 0.04 because of the size of their vehicles and the risk they carry.
-
28. What should a driver do first after passing this sign?
Show answer
Answer A: Move into the right-hand lane and stay there
Traffic returns to two-way operation, so the driver keeps to the right of the centerline and stops treating the left side as available.
-
29. As a driver keeps drinking, in what order are driving abilities usually lost?
Show answer
Answer C: Judgment, then vision, reaction time and coordination
Alcohol reaches the parts of the brain that handle judgment first, and only later does it visibly affect sight, reactions and muscle control.
-
30. Once a Wisconsin driver becomes eligible to reinstate driving privileges after certain violations, how long must an SR-22 filing stay in effect?
Show answer
Answer B: Three years from the reinstatement eligibility date
Wisconsin requires an SR-22 to remain on file for three years from the date the driver becomes eligible to reinstate driving privileges.
-
31. The road ahead is broken up with potholes and rough patches. What should you do?
Show answer
Answer C: Slow down, since a hole hit at speed can wreck a tire or wheel
A lower speed cuts the impact on tires, wheels and suspension and gives you time to choose a line through the rough surface.
-
32. A live power line is lying on your car and the car has caught fire, so you must get out. How should you leave it?
Show answer
Answer D: Jump clear without touching the car and ground at once, then shuffle away
Touching the vehicle and the ground together makes you the path to earth, and long strides can bridge the voltage spread through the ground.
-
33. For an alert driver, about how long is the reaction time once a hazard has been recognized?
Show answer
Answer A: About three quarters of a second
Reaction alone takes roughly three quarters of a second for an alert driver, and perception takes about as long again, so a second and a half of travel is added before the brakes bite.
-
34. You are turning left into a street that is divided by a raised median. Which side should you enter?
Show answer
Answer C: The right-hand roadway, so that you travel on the proper side
A raised median separates two directions of travel, so the turn must be completed into the roadway carrying traffic your way.
-
35. What Wisconsin credential lets a rider legally operate a moped on a public road?
Show answer
Answer C: A regular or probationary Class D license, or a moped permit earned through an approved driver education course
Wisconsin allows moped operation with a Class D regular or probationary license, or with a moped permit obtained after an approved driver education course; an instruction permit alone is not enough.
-
36. You come upon a person riding a horse on the roadway ahead of you. What is the correct way to pass?
Show answer
Answer A: Slow down, give plenty of room and do not use the horn
Horses startle easily, and a frightened horse can throw its rider into your path. Pass slowly and wide, and avoid any sudden noise.
-
37. Is it a good idea to shift into neutral and coast down a long hill to save fuel?
Show answer
Answer B: No, you lose engine braking and some control of the vehicle
In neutral the engine cannot help slow the vehicle, so the brakes do all the work and can overheat. Stay in gear so the drivetrain helps hold your speed.
-
38. Besides proof of name, date of birth, and legal presence, what else must a Wisconsin REAL ID applicant provide?
Show answer
Answer C: A Social Security number and two separate proofs of address
Wisconsin requires a REAL ID applicant to also provide a Social Security number and two separate proofs of address, in addition to proof of name, birth date and legal presence.
-
39. Blue pavement markings are used together with white markings at
Show answer
Answer D: parking spaces reserved for people with disabilities
Blue supplements the white markings of accessible parking spaces, which is the only assignment blue has on the pavement.
-
40. You are approaching a sharp curve. When should you reduce your speed?
Show answer
Answer D: Before you enter the curve, so you can accelerate gently through it
Braking hard inside a curve uses up the traction that is already being demanded for cornering, so the slowing must be finished before you enter.
-
41. 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.
-
42. You are about to pass a large truck on a two-lane highway. Which practice is correct?
Show answer
Answer A: Finish the pass without delay and expect wind turbulence beside the truck
Lingering beside a truck keeps you in its blind spot and exposes you to air turbulence. Pass on the left, keep moving, and move back only when you can see the whole truck in your mirror.
-
43. What is the safe way to carry a dog in a car?
Show answer
Answer C: In a secured crate, or in a harness attached to a seat belt anchor
An unrestrained animal distracts the driver and becomes a heavy projectile in a crash, so it should be crated or harnessed.
-
44. At what age or weight does Wisconsin require a child to ride in a rear-facing car seat in the back seat?
Show answer
Answer A: Under 1 year old or under 20 pounds
Wisconsin requires a child under 1 year old or under 20 pounds to ride in a rear-facing child seat in the back seat.
-
45. How does being tired change your total stopping distance?
Show answer
Answer A: It lengthens it, because you take longer to notice and react
Fatigue stretches perception and reaction time, and every extra fraction of a second is added distance before the brakes even begin to work.
-
46. Visibility drops suddenly and you decide to leave the highway. What is the safest way to do it?
Show answer
Answer A: Take the next exit or a wide pull off, well clear of the traffic lanes
Get right off the traveled way, and off the shoulder too if you can, because vehicles in poor visibility often drift onto the shoulder.
-
47. A driver is thinking about overtaking a slower vehicle and sees this sign a short distance ahead. What does it mean for that pass?
Show answer
Answer B: The pass must be finished before the restricted section begins
The sign marks the start of a section where passing is prohibited, so a driver may not be on the left side of the road beyond it; any pass has to be completed before that point or not started at all.
-
48. Why would a restriction like this one be applied to a stretch of road?
Show answer
Answer A: Because there is not enough visible road ahead to complete a pass safely
Limits on overtaking are set where a hill, a curve or an obstruction leaves too little sight distance for a driver to pull out, pass and return before meeting oncoming traffic.
-
49. What triggers a mandatory ignition interlock device order for a Wisconsin first-time OWI offender?
Show answer
Answer C: A measured BAC of 0.15 or higher, or a refusal to submit to chemical testing
Wisconsin courts must order an ignition interlock device for a first-time OWI offender whose BAC was 0.15 or higher, or who refused a chemical test.
-
50. Comparing a first alcohol-related conviction to a second, how does the waiting period for a Wisconsin occupational license differ?
Show answer
Answer C: A first conviction allows immediate eligibility, while a second imposes a 45-day wait
Wisconsin allows immediate eligibility for an occupational license after a first alcohol conviction, but imposes a 45-day waiting period after a second.
