Varying speed limits through one area

[roadfro]

They used to, until a judge told them that advisory panels couldn't be enforced (aka be used as a way to raise revenue).

That's because, well duh, they're advisory panels and not meant to replace an actual speed limit.  Cops should be forced to read the MUTCD before they get assigned to traffic duty so they can better understand what the hell they're trying to actually enforce.

One problem... Cops don't enforce the MUTCD, since it is not the law.
