I get signs telling you there’s a bump ahead, or deer might run out in front of you, but I’ve never understood why there are signs telling people not to build unlawful driveways. Are that many people doing it on a daily basis in that area that they need a fully visible sign? Surely it’s just an ordinance, why does it need a road sign?
I’ve been wondering this for years and hope someone has an answer that makes sense.
The MUTCD has signs for “other regulatory” purposes which are to remind drivers on what the law is.
And highway maintenance is such that roads aren’t going to be inspected for years at a time.
