What is the speed limit in residential areas if not posted?

In Virginia, when no specific speed limit is posted in residential areas, the default speed limit is 25 miles per hour. This regulation is designed to enhance safety in neighborhoods where children may be playing, pedestrians are more common, and visibility may be limited. A speed limit of 25 mph allows drivers to maintain control of their vehicles while providing ample time to react to unexpected situations, such as a child darting into the street or other hazards that could arise in a residential setting.

Following this default speed limit helps create a safer environment for all road users and ensures that drivers are aware of the need to slow down in areas where there may be more foot traffic and potential obstacles.
