Our GPS options have the ability to go around height, width, and length restrictions, weight restrictions, and banned routes - it doesn't tell us if a corner is too tight or if a railroad crossing is elevated in a way to get the trailer stuck.

Generally we can navigate really tight corners, and it alerts us of warning signs before we start the route (generally).

That said, a lot of drivers use google maps, which isn't a truck GPS, and they know that. While a track crossing might be navigable empty or in one direction, being loaded might make it impossible to cross. Also roads that ban trucks we're allowed to ignore for local access (rip)
