What should I expect if I am interested in trucking and just leaving Highschool?

I am graduating this year, and have always been interested in jobs that let you travel ie. trucking.

I also like the individualized aspect that come with some jobs such as forestry. I want to know what I should expect right after high school?

I know that I have to be certified through a school and then begin. Should I worry about expenses and start saving in anticipation?

If I am only 18 and the required Out-of-state age is 21 to drive, should I wait to go to school and get a local job doing whatever.

I'm sorry if this is kind off vague, but hopefully you get the gist of what I am asking.

Thanks! -Jacob
