It might not be as simple as it seems. I kid you not - one of my friends did try his hand in trucking and he told me that it is not that easy. Furthermore, the trucking hours are extremely long and tiring. But of course what you get is perhaps the sense of freedom and the open road. That could be the reason why a lot of people take up trucking as their main source of income. I myself have never tried that line of work. But from what I know, in order to be a trucker, you will have to go through this source to get the commercial drivers license. It takes about 3 weeks or so. They are based in Colorado. Their main goal is to ensure that you become a good and safe truck driver. Hopefully. You will be spending hours and hours on the road, so you better be a safe truck driver.  They also offer courses to trains as trailer and bus drivers as well. So if you are living somewhere nearby and you would like to get these certifications, you might want to check them out.
