You do have to have a phone number for Dept of Ag if doing any pesticide or fert apps, though.ManForAll said:One potential help with requirement of putting the city/state on the trucks. Here in Michigan at least, you can register your logo with the state and get it "service marked" like a trademark. As long as you do this, there is no requirement to put a city and state on the truck in any size lettering. You just have to keep a copy of the state paperwork in the vehicle in case motor carrier pulls you over, and around here they do ALL the time.
For you Michigan guys, I believe the lettering requirement here is 3 inches high.
