In the main I use Google maps. Street view and satellite imagery combined are an excellent free tool for our line of work.
This, combined with a Truckers Atlas for Bridge Heights does for me.
Surely most (particularly Artic drivers with tall trailers) truckers have a big heavy spiral bound atlas with bridge heights?
My truck has a satnav inbuilt. I’ll use it when going somewhere new. To use it blindly suggests dumbbugger status.
