The speed limit in an urban district on a street is __________ mph unless a special hazard requires a slower speed.

In urban districts, the designated speed limit is typically set at 30 mph. This limit is established to enhance safety in areas where pedestrians, cyclists, and vehicles share the road, ensuring that drivers have adequate time to react to potential hazards. The lower limit reflects the higher density of people and vehicles commonly found in urban areas, compared to rural settings where higher speeds might be more appropriate due to less congestion and fewer obstacles.

While the law allows for speed adjustments based on special hazards, the base limit of 30 mph serves as a standard guideline that drivers are expected to follow, creating a consistent and predictable environment for everyone on the road.
