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

In Delaware, the typical speed limit in residential areas is set at 25 mph unless otherwise posted. This speed limit is established to enhance safety for residents, particularly for children playing and pedestrians walking in these neighborhoods. Slower speeds allow drivers more time to react to unexpected situations, which is essential in areas where traffic patterns can be more unpredictable due to the presence of homes, parked vehicles, and foot traffic.

The other options represent speed limits that are typically found in different contexts, such as school zones or more rural and highway settings. The choice of 25 mph aligns with practices across many states aimed at promoting safer community environments through reasonable and cautious driving speeds in residential neighborhoods.
