This notice is posted on the web site of my NJ township’s department of public works:
“Citizens are reminded that it is illegal to attempt
to unlawfully reserve street parking.
Doing so may risk removal of offending material as
the case requires.”
Of course, many people are either unaware of or ignore that rule.
A well-respected posek in my town lives near the train station where there’s a lot of competition for parking spots, especially when snow piles block a bunch of them. When I attempted to use the cleaned out spot in front of his house, he came out and forbade me from doing so, claiming that it was reserved for his wife’s car.
I understood his position all too well and I did eventually find a spot quite a distance from the train station, but I was not a happy camper.
