The concept of a 'license' is one made by the government as a means of controlling citizens and preventing uprising. The last thing they want is people fork lifting protest banners up onto the Capitol dome, so they make it difficult for us to drive them. Skip the license, and lets be honest, you should skip training all together, you can learn on the fly. There are only like 6 pedals and 2 joysticks, and maybe a few buttons. Forward will make it move forward, and back backwards. Or maybe that lowers the boom? Regardless, just go for it.
Here is a great link that you should follow though. It will teach you how to use a sewing machine, which we will need to make our protest banners that we will forklift up when we visit DC. https://www.noodle.com/learn/details/23663/how-to-use-a-sewing-machine
