On a road posted at 55 mph, a truck ahead is actively plowing snow. What minimum following distance does Wisconsin’s snowplow rule require?
Correct answer: At least 200 feet.
Following within 200 feet of a vehicle engaged in snow or ice removal is prohibited on roads posted above 35 mph. This question concerns following a working plow, not a blanket ban on passing every maintenance truck.

On a reversible roadway, the signal facing your direction shows a red X while a signal facing opposing traffic permits movement. What should you do?
Correct answer: Keep out of that lane in your direction.
A reversible lane can be open in one direction and closed in the other. Follow the signal facing your own approach, not the one displayed to opposing traffic.

You can see the main body of a snowplow, but blowing snow hides its side. Why should you leave generous lateral clearance?
Correct answer: A wing blade may extend beyond the visible body of the truck.
Plow wings can project several feet beyond the truck and be obscured by snow. Do not judge the machine’s clearance solely from the part of the body you can see.

Your turn arrow changes from green to steady yellow before you enter the intersection. You have room to stop safely. What should you do?
Correct answer: Stop before entering because the protected turn phase is ending.
A steady yellow arrow warns that the turn signal is changing. Stop when you can do so safely; it is different from a flashing yellow arrow that allows a yielding turn.

A county snow-removal vehicle displays a flashing green warning light. How should you interpret it?
Correct answer: As a permitted maintenance warning, not a traffic signal granting you passage.
Wisconsin permits certain county and municipal maintenance vehicles to use flashing green warning lights. They help drivers notice the equipment; they do not give nearby motorists a green-light right of way.

The colors of a standard vertical three-light signal are difficult for you to distinguish. Where is its red light positioned?
Correct answer: At the top of the signal.
On the standard vertical arrangement, red is above yellow and green. Position is an additional recognition cue, not a substitute for paying attention to the signal.

A snow cloud limits your view as you consider passing a working plow. What should you expect about the untreated road ahead?
Correct answer: It may be worse than the road already treated behind the plow.
The plow is improving the surface as it moves. Poor visibility and potentially worse conditions ahead make a rushed pass dangerous; give the operator room.

A red turn arrow is flashing and no officer is directing traffic. What must you do before making that turn?
Correct answer: Stop completely, then proceed only when the turn is safe.
A flashing red arrow requires a complete stop followed by yielding before a safe turn. It does not provide the protected movement of a green arrow.

A round yellow sign with a black X and the letters RR appears ahead of the tracks. What does it warn you about?
Correct answer: A railroad crossing ahead that requires your attention.
This advance warning sign alerts you before a rail crossing. Reduce speed as appropriate and look for tracks, warning devices and trains; the sign does not grant priority to road traffic.

Your car is safely stopped off the road during a snowstorm, with no fire or other immediate danger. While waiting for help, what is usually safest?
Correct answer: Stay in the car with your seat belt on.
In these conditions, the car usually offers protection from weather and sliding vehicles. This advice does not apply to a car on railroad tracks or a vehicle with an immediate fire or similar danger.

A plaque under a railroad crossbuck reads “3 TRACKS.” What information should guide your crossing decision?
Correct answer: There are three tracks to check for trains before crossing safely.
The plaque gives the number of tracks. A train clearing one track does not prove the others are clear; look for traffic on every track.

Snow has piled around the rear of your stranded car. Before running the engine briefly for warmth, what must you check?
Correct answer: That the exhaust is working and its outlet is not blocked by snow.
A blocked exhaust can allow dangerous carbon monoxide to build up. Check the exhaust before using the engine for heat, and do not assume an idling vehicle is safe with a snow-blocked outlet.

A long train has just cleared one of several tracks, but it still blocks your view of another track. What is the danger?
Correct answer: Another train may be hidden behind the first one.
At multiple-track crossings, one train can hide another traveling in either direction. Wait until you can see clearly and all crossing warnings allow a safe movement.

With the exhaust clear and working, you need heat while waiting in a stranded car. Which approach matches WisDOT guidance?
Correct answer: Run the engine only for brief periods when needed; avoid a portable heater inside.
WisDOT recommends brief engine use when heat is necessary and warns that portable heaters in enclosed spaces are dangerous. It does not prescribe one fixed timing schedule for every situation.

An adult passenger puts the shoulder belt under an arm to make it feel less restrictive. What adjustment is needed?
Correct answer: Route it over the shoulder and across the middle of the chest.
The shoulder belt belongs across the chest, away from the neck—not under an arm or behind the back. Proper placement helps load stronger parts of the body during a crash.

Where should an adult position the lap portion of a properly worn seat belt?
Correct answer: Low across the hips, rather than across the stomach.
The lap portion should lie across the pelvis and hips. Wearing it over the abdomen can direct crash forces toward vulnerable soft tissues instead of the stronger pelvic area.

You have stopped safely near a crossing and believe its warning equipment is malfunctioning. What is the appropriate reporting step?
Correct answer: Use the posted railroad emergency number to report the problem.
The blue-and-white sign provides a contact for crossing hazards, including warning-device problems. A suspected malfunction is not permission to ignore a gate or other active warning.

You become unsure of your route and need to study a map in detail. What should you do?
Correct answer: Find a safe place to stop before reading it.
Reading a map takes attention and vision away from driving. Stop somewhere safe before studying the route; slowing slightly while continuing to read does not remove the distraction.

You are driving a manual-transmission vehicle toward railroad tracks. When should you select a gear suitable for completing the crossing?
Correct answer: Before entering the tracks so you do not need to shift on them.
Choose the gear before crossing and keep moving smoothly across the tracks when it is safe to enter. Avoid a gear change that could interrupt power and leave you stopped in danger.

You are choosing where to store blankets, water and a flashlight for winter emergencies. Why might the back seat be better than the trunk?
Correct answer: The supplies remain reachable if the trunk jams or freezes shut.
WisDOT suggests considering accessible storage because a trunk may be jammed or frozen. This is preparedness guidance, not a legal requirement to carry a particular kit. Secure supplies so they do not become hazards.
