What is the speed limit in residential areas unless otherwise posted?

Answer: B — 25 mph

In Wisconsin, the default speed limit in residential areas is set at 25 miles per hour unless there are signs indicating a different limit. This speed limit is designed to enhance safety in neighborhoods where pedestrians, children, and pets may frequently be present. A lower speed limit helps ensure that drivers have adequate time to react to unexpected situations, such as a child running into the road or a parked vehicle obstructing the driver's view. By prioritizing safety in residential areas, this limit contributes to a more secure environment for all who live and travel within those zones.
