What is the speed limit in urban areas in Alaska, unless otherwise posted?

In urban areas of Alaska, the default speed limit is 25 mph, unless there are specific signs indicating a different limit. This regulation is designed to promote safety in areas where there are higher pedestrian activities, residential neighborhoods, and increased interaction between vehicles and people. Reducing speed limits in urban settings helps decrease the likelihood and severity of accidents, as motorists have more time to react to unexpected situations, such as pedestrians crossing the street or vehicles entering traffic.

While the other choices represent speed limits that might be encountered in different contexts or areas, they do not align with the established default speed limit in urban settings. For example, lower limits like 20 mph may apply in school zones, but they are not the general urban speed limit. Higher limits might be more appropriate for rural areas or major roadways, but again, do not reflect the standard in urban regions. Understanding these set limits is crucial for safe driving practices in Alaska.
