Once Waze integrates that law into their dataset the problem is solved. No sign required.
I suppose they can't crowdsource that information or people would lie.
There must be a system for getting traffic information from municipalities to the road databases. Apple Maps told me there was no way to drive home a couple days ago, on examination the street in front of my house was marked as closed for the day, they were paving. That is essentially a zero traffic street in a grid area but bisected by rail road tracks without a crossing, so no one uses it except the people who live on it.
Sign still required for those w/o Waze, but you bring up a fair point: not all municipalities are willing to open their data. Having a countrywide open database - updated by the municipalities directly, not crowdsourced like OSM - would help with many things, not just routing.
