What are the typical hours for Wisconsin school zone speed limits?

The typical hours for Wisconsin school zone speed limits are usually in effect when children are present, which is commonly during school hours. This means that drivers should be especially cautious and adhere to the reduced speed limits at specific times when students are arriving or leaving school. These hours are generally set to ensure the safety of children who may be crossing streets or walking in the area.

School zone speed limits are specifically designed to protect children who are likely to be in the vicinity. The presence of kids during school hours is a critical factor for determining when these speed limit reductions apply. In contrast, the other options do not accurately reflect the safety considerations in place for school zones. Speed limits that are always in effect or that apply only during night hours do not account for the peak times when children are most active. Additionally, limiting speed limits to only school holidays would not provide adequate protection during regular school days when children are present. Thus, the correct answer highlights the connection between school hours and child safety in school zones.
