Question: 1 / 400

What is the speed limit posted on typical roadways?

20 mph

30 mph

The speed limit of 30 mph on typical roadways is based on a standard approach used in urban settings where the roads are often designed for lower-speed travel due to higher pedestrian activity, intersections, and potential hazards. This speed limit reflects the need to balance efficient transportation with safety, allowing drivers sufficient speed while still being able to react to unexpected situations or obstacles.

While there are other speed limits, such as 20 mph in residential areas or 40 and 50 mph on certain larger roads or highways, 30 mph often serves as a baseline for many types of roads where both residential and commercial activities are present, ensuring that traffic can flow reasonably while maintaining a safer environment for all road users.
