This is a tricky one to research. From what I can tell (in the USA) it's not necessarily illegal to drive with the fog lights on at all times. The main requirement for all headlights anywhere is that they're positioned and aimed correctly. Specific states or regions may technically have restrictions, but it seems pointless to enforce if it's a stock vehicle that meets the requirements. High beams are way worse than the typical fog lights. I don't think most people should have to worry about their fog lights unless they're aftermarket. Reminds me of those signs that say "no engine braking". They're specifically referring to jake brakes on commercial vehicles, not dropping a gear on a normal car or truck.
