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

In most jurisdictions, the standard speed limit in residential areas is 25 mph unless otherwise posted. This speed limit is set with the intention of enhancing safety for pedestrians, cyclists, and other motorists who may be present in these areas. The 25 mph limit allows for better reaction time for drivers in case of unexpected hazards, such as children playing or pets running into the street, which are more common in neighborhoods.

While other speed limits are in use in specific contexts, the 25 mph limit effectively balances safety and mobility in residential settings, acknowledging that these areas have a different traffic dynamic compared to main roads or highways. Lower limits like 15 mph might be used in certain school zones or areas with particularly high pedestrian traffic, while limits of 30 mph may be applicable on larger residential streets that are designed to accommodate through traffic. Thus, the 25 mph limit serves as a vital guideline for ensuring community safety.
