I’ve been driving truck for close to 30 years; black ice is extremely difficult to notice at night. Aside from the typical overpasses, low lying areas and sections of road adjacent to water - simple random black ice cat get you before you know it. Wisconsin is notorious for it as westerly/northwesterly winds are free-flowing straight line.
I certainly don’t envy you for doing what you do. I drove our own lowboy for 20 years hauling our heavy and wide load equipment. 100,000 pounds and 100 feet long
But I could be selective on days it wasn’t fit and only about 100 mile radius
That was enough for me to decide I never wanted to be a long hauler
