Salting of roads is only done a very narrow band of environments, the UK sitting in the middle of it. If it’s too cold, only a couple of degrees lower than a UK winter, then the salted melt water will re-freeze into deadly black ice. I believe the UK is fairly unique in how much we salt roads, most other countries will grit roads but not salt them.
