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

The speed limit in residential areas is 25 mph unless otherwise posted. This speed limit is designed to enhance safety in neighborhoods where pedestrian foot traffic is common, particularly with children playing, pets, and various other activities that occur near homes. Keeping the speed limit to 25 mph allows for a greater reaction time for drivers to respond to sudden movements or dangers that may arise, such as children darting into the street or other unexpected obstacles.

Additionally, this standard is set to promote a safer community environment, encouraging drivers to act with heightened caution in areas where people are more likely to be present, which can help prevent accidents and injuries. Other options represent higher speed limits that would not be suitable or safe in residential contexts, as they would increase the risk of collisions in these more densely populated, activity-filled areas.
