1. The crossbuck, formed by two rectangular arms crossed in an X, is placed
Show answer
Answer D: on each highway approach to a railroad grade crossing
The crossbuck marks the location of a highway-rail grade crossing and is required on each highway approach to that crossing.
-
2. Why should you avoid parking over tall dry grass or a pile of dead leaves?
Show answer
Answer B: Because the hot exhaust can set the dry material on fire
The exhaust system stays hot for a long time after a drive and can ignite dry vegetation underneath the vehicle.
-
3. You have fitted small convex blind spot mirrors to the door mirrors. What is true of them?
Show answer
Answer A: They help a good deal, but you should still look over your shoulder as well
Add-on mirrors reduce but do not remove the blind spot, and they make vehicles look smaller and further away.
-
4. You realize you have just gone past your exit on a freeway. What should you do?
Show answer
Answer C: Carry on to the next exit and turn around there
A missed exit costs a few minutes, while backing up or cutting across the striped gore area puts you in the path of traffic that is not expecting it.
-
5. You see an open curb space on the opposite side of a two-way street. What should you do?
Show answer
Answer B: Drive on, turn around, and come back on that side
You must park on the right, facing the direction of travel, so reaching a space on the other side means going around rather than crossing into it.
-
6. You have turned onto a street and see parked cars facing you and headlights coming toward you. What has probably happened?
Show answer
Answer C: You have turned the wrong way onto a one-way street
Vehicles parked facing you and headlights approaching in your lane are the classic signs of driving against the flow on a one-way street.
-
7. You must stop for a train at a highway-rail crossing. Where should you stop?
Show answer
Answer B: Behind the stop line, gate or signal and well clear of the nearest rail
Stop behind the stop line, gate or flashing-light signal and well clear of the nearest rail, because a train overhangs its track by several feet on each side.
-
8. Two vehicles reach a four-way stop at the same moment from adjacent roads. Who should go first?
Show answer
Answer A: The driver on the right
When two drivers stop at a four-way stop at the same time, the driver on the left yields to the driver on the right.
-
9. Traffic ahead of you has stopped in your lane while the next lane is still moving. What is the first thing to do?
Show answer
Answer C: Slow down first and check the next lane before moving over
Braking is the action that keeps you from hitting the stopped traffic, and the lane change is only safe once you have looked.
-
10. A large panel mounted on a trailer at the roadside displays a flashing arrow pointing left. What does it tell you?
Show answer
Answer B: Move into the lane to your left
An arrow panel directs traffic out of a closed lane, so the arrow shows the direction you must move rather than the shape of the road ahead.
-
11. A small plate under a stop sign reads CROSS TRAFFIC DOES NOT STOP. What is it telling you?
Show answer
Answer D: Traffic on the cross street is not required to stop at all
The plate warns that the other road is uncontrolled, so you must wait for a gap instead of expecting anyone to take turns with you.
-
12. A law enforcement officer is directing traffic and waves you forward while the signal facing you shows red. What should you do?
Show answer
Answer A: Follow the officer's direction and proceed
Directions given by an officer controlling traffic take priority over signals, signs and pavement markings.
-
13. Which of the four blind spots around a tractor-trailer is the largest?
Show answer
Answer A: The one on the right side of the truck
A truck has no-zones on all four sides, and the right-side blind spot is the largest because it runs back along the trailer and reaches across more than one lane.
-
14. A steady green arrow pointing left is displayed for your turning lane. What does it tell you?
Show answer
Answer D: The turn is protected because conflicting traffic is being held
A steady green arrow gives a protected movement in the direction shown, although you still yield to pedestrians and to any vehicle already inside the intersection.
-
15. Do hazard lights make it legal to leave your vehicle in a no parking zone?
Show answer
Answer A: No, they warn other drivers but do not permit the parking
Hazard lights are a warning device, not a permit; the parking restriction applies whether they are flashing or not.
-
16. Someone appears seriously injured after a crash. What should you generally do?
Show answer
Answer C: Call for emergency help and avoid moving the person unless there is an immediate danger such as fire
Moving an injured person can worsen spinal or internal injuries, so summon trained help and leave the person in place unless staying there is more dangerous than moving.
-
17. A line beside your lane is painted about twice the normal width. What does the extra width convey?
Show answer
Answer B: Greater emphasis on the restriction it carries
Width is part of the marking code: a wide line carries more emphasis than a normal one, which is why it is used at gores and channelizing lines.
-
18. You park facing downhill on a one-way street where the curb is on your left. Which way do the front wheels go?
Show answer
Answer A: Left, toward the curb on that side
Standard practice follows the curb rather than the side of the road: facing downhill the wheels point into the curb so a rolling vehicle is stopped by it. States differ on whether this is legally required.
-
19. A school crossing guard steps into the roadway and holds up a stop paddle. What must you do?
Show answer
Answer D: Stop and stay stopped until the guard and the children have left the road
A crossing guard directs traffic with legal authority; you must remain stopped until both the guard and the children are clear of the roadway.
-
20. A driver stopped at a red signal wants to turn right and this sign is posted at the corner. What is permitted?
Show answer
Answer A: Nothing: the turn is barred whether the signal is red or green
The restriction works independently of the signal, so the usual permission to turn right after stopping at a red light does not exist where this sign is posted.
-
21. You have brought the vehicle under control after a blowout. What should you do next?
Show answer
Answer A: Signal and coast well off the road before stopping
Let the speed fall, signal, and leave the roadway as far from traffic as you can before you stop. Driving on a failed tire ruins the wheel and risks control.
-
22. Where can an opened bottle of alcohol legally be kept in a Wisconsin vehicle while it is being driven on a highway?
Show answer
Answer A: In the trunk, or in an area not normally occupied by the driver or passengers if there is no trunk
Wisconsin's open container law exempts an opened alcohol container kept in the trunk, or in an area not normally occupied by the driver or passengers if the vehicle has no trunk; a glove compartment does not qualify for this exception.
-
23. What should you avoid when a hostile driver pulls alongside you?
Show answer
Answer A: Making eye contact, or answering the gestures in any way at all
Any response, including a look, encourages an aggressive driver, so give none and let the vehicle go.
-
24. You are making a legal U-turn at an intersection. Who has the right of way?
Show answer
Answer C: Everyone else, until your turn is complete
A U-turn crosses several paths at once, so you yield to oncoming vehicles, to crossing traffic and to pedestrians before starting it.
-
25. You are parked legally, but a police officer tells you to move the vehicle. What should you do?
Show answer
Answer B: Move it as directed, because an officer overrides the signs
Directions from a police officer or a firefighter take precedence over signs and markings, whether they are directing traffic or clearing a street.
-
26. You approach a one-lane bridge and there is a yield sign facing your side of it. What does that mean?
Show answer
Answer B: Oncoming traffic crosses the bridge first and you wait at the approach
At a one-lane bridge the yield sign tells one direction to give way, so you wait clear of the bridge until oncoming traffic has crossed.
-
27. What age, weight, and height combination marks the band in which Wisconsin requires a booster seat if a forward-facing harness seat is not used?
Show answer
Answer A: Ages 4 to 8, weighing 40 to 80 pounds, and no taller than 4 feet 9 inches
Wisconsin requires a child between ages 4 and 8, weighing 40 to 80 pounds, and no taller than 4 feet 9 inches to use a booster seat if not still in a forward- or rear-facing harness seat.
-
28. What is the best way to keep your phone from distracting you on a trip?
Show answer
Answer D: Silence it and stow it before you start
A phone you cannot hear and cannot reach cannot tempt you, which is far more reliable than deciding case by case while you drive.
-
29. What do zero tolerance laws mean for a driver who is under 21?
Show answer
Answer B: They commit a violation at an alcohol level far below the adult limit
Drivers under 21 may not legally drink, so every state sets a limit far below the adult one and treats even a trace reading as a violation. The exact figure is set by each state, and the penalty usually includes losing the license.
-
30. What does a sign reading Slower Traffic Keep Right require?
Show answer
Answer C: Traffic moving slower than the general flow must use the right-hand lane
The sign applies to any vehicle traveling below the speed of the traffic around it, which must keep right so faster vehicles can use the lanes to the left.
-
31. A broken white line separates your lane from the lane beside it. What does it indicate?
Show answer
Answer C: Both lanes carry traffic in the same direction and lane changes are permitted
White lines separate lanes of traffic moving in the same direction, and a broken white line means changing lanes across it is permitted when it is safe.
-
32. A new Wisconsin resident holds a valid out-of-state license. When does WisDOT require a full road test before issuing a Wisconsin license?
Show answer
Answer C: When that out-of-state license has been expired for more than 8 years
Wisconsin only requires knowledge, signs and road testing again for a new resident whose out-of-state license has been expired more than 8 years; otherwise the road test is skipped.
-
33. A square sign with a red field, a wide white horizontal bar and the words DO NOT ENTER tells a driver that
Show answer
Answer B: the roadway ahead must not be entered from that point
The do not enter sign is posted at the end of a one-way roadway or ramp to keep traffic from driving into it against the flow.
-
34. You are approaching the entry of a roundabout and a pedestrian is crossing the marked crosswalk on your approach lane. What must you do?
Show answer
Answer D: Stop before the crosswalk and let the pedestrian cross
Roundabout crosswalks sit a short distance back from the yield line, and drivers must yield there before they ever reach the circulating lanes.
-
35. The electric windows will not work as your vehicle sinks in water. What is the best option?
Show answer
Answer C: Break a side window with a hard, pointed object and climb out through it
Side windows are tempered glass and can be broken, while the laminated windshield cannot, and water pressure holds the doors shut.
-
36. What change in the road does this sign announce?
Show answer
Answer B: The two directions of travel are about to be separated, and the driver must keep to the right of the separation
Ahead the roadway splits into separate one-way roadways on either side of a median, so the driver stays to the right of the divider and no longer meets oncoming vehicles.
-
37. The gates at a railroad crossing are down, and you can see that the road beyond them is clear. What is the correct action?
Show answer
Answer A: Wait until the gates rise completely and the lights go out
Lowered gates mean rail traffic is expected, and driving around them removes the only protection the crossing provides.
-
38. A sign at the signal reads LEFT TURN ON GREEN ARROW ONLY. The ball turns green but no arrow appears. What may you do?
Show answer
Answer C: Wait, because your turn is allowed only while the arrow is showing
The sign removes the permissive turn, so the left is legal only during the green arrow and you must wait behind the line until it appears.
-
39. Traffic in your lane is backed up and the paved shoulder looks clear. May you drive along it to get past?
Show answer
Answer C: No, the shoulder is not a travel lane
Passing must be done within the roadway; driving on the shoulder to get around traffic is prohibited and surprises anyone entering from the right.
-
40. Why is it often safer to back into a parking space than to back out of one?
Show answer
Answer D: Because you leave the space going forward, with a clear view
Backing into the space puts the difficult maneuver where you are stopped and looking around, and lets you drive out facing the traffic and pedestrians.
-
41. How much more energy must your brakes absorb if you double your speed?
Show answer
Answer D: About four times as much, since energy rises with the square of speed
Kinetic energy grows with the square of speed, so twice the speed means about four times the energy and a far longer braking distance.
-
42. A white arrow painted in your lane points only to the right, and a sign above the lane shows the same movement. What must you do?
Show answer
Answer C: Turn right from that lane
Pavement arrows used with lane-use signs are regulatory, so a driver occupying that lane must make the movement shown.
-
43. The green left-turn arrow ends and a steady red ball comes on for your lane, at an intersection where no turn on red is allowed. What must you do?
Show answer
Answer D: Stop and wait, because no turn is allowed while the red ball is lit
Once a red indication faces your lane and no turn on red is permitted there, the turn is over; only a vehicle already inside the intersection completes its movement.
-
44. Must a Wisconsin law enforcement officer personally witness a driver illegally passing a stopped school bus to issue a citation?
Show answer
Answer A: No, the bus driver's report to law enforcement within 24 hours is enough
Wisconsin allows a vehicle owner to be cited for illegally passing a school bus based solely on the bus driver's report, made to law enforcement within 24 hours, without an officer witnessing it.
-
45. How often may a Wisconsin driver use Traffic Safety School to reduce demerit points, and how quickly must DMV be notified after finishing the course?
Show answer
Answer B: Once every three years, and DMV must be notified within 30 days of completion
Wisconsin allows a driver to reduce demerit points through Traffic Safety School only once every three years, and requires notifying DMV within 30 days of finishing the course.
-
46. The blue signs mounted before a freeway interchange that carry the logos of individual businesses are
Show answer
Answer C: specific service signs, which show the brands available at that exit
Specific service signs, often called logo signs, list eligible businesses for categories such as gas, food, lodging, camping, attractions and 24-hour pharmacies at the upcoming interchange.
-
47. Some states allow a left turn against a red light. Which movement is it?
Show answer
Answer A: A left turn from a one-way street onto another one-way street
The movement generally allowed on red is one-way to one-way, because the turn does not cross any lane of oncoming traffic; a few states also extend it to a two-way street turning onto a one-way street.
-
48. A yellow diamond shows an arrow that doubles back on itself. What kind of curve lies ahead?
Show answer
Answer C: A turn of 135 degrees or more, nearly doubling back
The hairpin curve sign is used where the road changes direction by 135 degrees or more, and it is normally backed up by chevrons or a large arrow through the bend.
-
49. You hear a bang and one of the front tires deflates while you are on the highway. What happens to the vehicle?
Show answer
Answer D: It pulls strongly toward the side that failed
The collapsed tire drags heavily on that corner, so the vehicle veers toward it. Hold the wheel firmly, keep your line and let the speed fall before leaving the road.
-
50. What do yellow lines painted on a roadway separate?
Show answer
Answer D: Traffic moving in opposite directions
Yellow markings separate opposing streams of traffic, and they also mark the left edge of a divided highway or a one-way roadway.
