What is the speed limit in a residential area in Utah unless otherwise posted?

In Utah, the default speed limit in residential areas is set at 25 mph unless otherwise indicated by posted signs. This speed limit is designed to enhance safety for pedestrians, cyclists, and residents who may be entering or exiting driveways or walking along the street. The lower limit helps to reduce the severity of accidents in areas where people are more likely to be present, such as neighborhoods where children play and families walk.

Understanding the rationale behind this speed limit is key for new drivers, as it emphasizes the importance of caution in areas with higher foot traffic. In contrast, higher speed limits like 35 mph or 50 mph are more appropriate for urban or rural roadways where traffic flow is typically higher and there are fewer pedestrians. The 15 mph limit is also not widely applicable, as it is generally reserved for specific zones such as school zones or certain playground areas.
