That sounds about right. According to American Legal Publishing, one of three major municipal code publishers, there are 13,102 municipal ordinances related to speed limits across the United States.[1] Some are redundant to state laws regarding municipal speed limits, but most override state laws either up or down, depending on the state’s need for speed. That’s a big wiki table.
I’m not sure defaults relations would be much better. The closer you look at these ordinances, the more you realize they were written by English majors specializing in creative writing rather than Computer Science majors with a specialty in database design.
Set “Select document types to include” to “Codes Only” and “This exact phrase” to
speed limit, and enable “Find alternate word forms (stemming)”. ↩︎
