What is the speed limit in a residential district in a city unless a higher speed is posted?

In Wisconsin, the speed limit in a residential district is set at 25 miles per hour unless there are signs posted indicating a different speed limit. This regulation is designed to enhance safety in areas where pedestrians, particularly children, are likely to be present, such as near homes, schools, and parks. The lower speed limit helps drivers react quickly to unexpected situations, reducing the risk of accidents.

Other options indicate different speed limits, which do not apply in this specific context unless explicitly posted by signage. The standard 25 mph limit serves as a baseline to ensure that drivers maintain a safe speed in these typically high-traffic areas.
