Not entirely, but it impose some very important limits on any signs near highways, such as requiring them to be advertising something that's available from the same property under them.
That effectively blocks the most spammy and egregious forests of signs, because one can't just purchase a small rectangle of near-highway grass and start auctioning space above it to a large shifting pool of national bidders.
Don’t drive I-5 by Fife much, eh? Okay, you did say “usually”.
Redmond has an outright ban on billboards. That’s how I know where the Redmond/Kirkland border is (there’s a billboard on 124th St.) Now if they if they’d just follow King County on those fucking political signs. (King County says “not on public right-of-ways”, Redmond says “where ever you see a patch of grass”.)
It used to be true that near the FL/GA border you'd see billboards advertising "TOPLESS DANCERS" for 50 miles on either side of the fine establishment buying these billboards. The sheer number of them was almost a parody of billboards in a way.
I was shocked by the number of "One call, that's all" accident attorney billboards in LA and FL when I drove through them several years ago.
