They are not the first, Dumfries and Galloway did likewise, but none of which are enforceable without individual TROs. Public carparks are subject to the 1984 road traffic act. But let’s look at the logistics here, Highland region is about one third the size of Scotland, and very sparsely populated. Policing any ban would prove all but impossible. Simply putting up signs stating no overnight parking simply won’t cut it. Overnight in summer months simply does not exist, it never actually gets dark in summer so far north. Whereas in winter overnight could be from 4pm until 9am. What exactly constitutes overnight is debatable.
