What is the maximum speed limit in a business or residential area with no posted speed limits?

In areas designated as business or residential zones, the standard maximum speed limit, when not specifically posted, is generally set at 25 miles per hour. This limit is implemented to ensure the safety of pedestrians, cyclists, and residents, who are often present in these areas. Slower speeds allow for greater reaction times for drivers when navigating through neighborhoods or commercial districts where there may be unexpected hazards or changes in traffic patterns.

Choosing a speed limit of 30 miles per hour would be too high for these environments, potentially increasing the risk of accidents and reducing the overall safety of the area. Thus, the more commonly accepted limit of 25 miles per hour serves as a crucial guideline for maintaining safety in business and residential zones.
