Observation, Speed & SpaceStandalone practice

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?

Daylight conceptual view of blue car A following silver car B on a two-lane road that bends left. A hatched area marks road outside A’s view beyond curves or hills. The card states 50 mph, the 55 mph limit and 4 to 5 seconds of visible road. No safe speed, following-time value or stopping bracket is drawn; lengths are explicitly not measured.

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?You are first in line at a red light. The light turns green. What should you do before you drive into the intersection?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?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?
