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

The recommended speed limit in residential areas is 25 mph unless otherwise posted. This speed limit is designed to enhance safety for pedestrians, children playing, and cyclists, as residential neighborhoods often have increased foot traffic. Slower speeds allow drivers more time to react to unexpected situations, such as a child running into the street or a parked car opening a door.

Additionally, local laws and regulations tend to be structured around this standard to ensure that drivers maintain safe speeds in environments where people are more likely to be present. In contrast, the other options suggest higher speeds that do not adequately account for the potential hazards present in residential areas, such as close proximity to homes, schools, and community areas.
