Observation, Speed & SpaceStandalone practice
The posted limit is 45 mph. Fresh snow covers the road, and some drivers are still going about 45 mph. What speed does Wisconsin law require of you?
Correct answer: A speed that is safe for the snow, even if it is well below 45 mph.
Why
A speed limit is the highest speed allowed in good conditions, not a target. Snow, ice and rain reduce traction, so you need more distance to slow down, turn and stop. The handbook tells you to slow down when rain, snow or hail begins and to avoid driving on icy roads when you can.

Related Wisconsin questions
It is snowing, and traffic is heavier than usual. You use the handbook's four-second rule and add time for each bad condition. What is the shortest following time that the rule gives?The car ahead passes a mailbox, and you start to count: “one thousand one, one thousand two...” Your front bumper reaches the mailbox as you say “one thousand two.” The road is dry and traffic is light. What does this tell you?At night on an unlit rural road, your low beams light only a short part of the road ahead. The posted limit is 55 mph, and an oncoming car is about 400 feet away. What should you do about your speed?In daylight, you drive on a hilly two-lane road with many curves. Because of the curves and the hilltops, you can see only about 4 to 5 seconds of road ahead of your car. The posted limit is 55 mph, and you drive at 50 mph behind another car. What should you do?You are first in line at a red light. The light turns green. What should you do before you drive into the intersection?You drive on a street with houses on both sides, inside a Wisconsin city. You have seen no speed limit sign since you turned onto it, and no school is near. What is the highest speed that you may drive?
