In Florida, what is the legal speed limit for residential areas unless otherwise posted?

In Florida, the legal speed limit for residential areas is set at 30 mph unless otherwise posted. This means that in the absence of specific signage indicating a different maximum speed, drivers should adhere to this limit to ensure safety in neighborhoods where children might be playing, pedestrians are walking, and the general area is more populated. Speed limits in residential areas are typically established to protect the community and reduce the likelihood of accidents. Therefore, the correct answer emphasizes the importance of compliance with this standard in order to promote safer driving behaviors in areas with potentially higher pedestrian traffic.
