HOA Jurist stiction over Public Roads

Our HOA has given itself the right to limit overnight parking on the county owned street in front of our houses.
The rule limits overnight parking. Is this legal?

I would think that the rule would need to be in the covenants (vs. any other document) to be enforceable.

That said, if the rule is in other documents and nobody challenges the rule (possibly through the courts), then the board will likely continue to enforce.
