What is the default speed limit on all streets that are not designated freeways?

The default speed limit on all streets that are not designated freeways is 55 mph. This speed limit is established to promote safety and ensure a reasonable and consistent driving speed on residential and urban roadways. It reflects the understanding that streets in these areas often have more traffic, pedestrians, and potential hazards than highways, necessitating a controlled speed to minimize accidents.

Urban planning and traffic studies have shown that limits set around this speed can help reduce both the severity and frequency of collisions. Lower limits exist in school zones or specially designated areas, but the general rule for non-freeway streets remains at 55 mph. This serves as a guideline for drivers to maintain a safe and efficient flow of traffic while being mindful of the varied environments they typically encounter on non-freeway roads.
