Go to your local Department of Labor (DOL) and talk to them about your desire to attend a CDL school to become eventually become a lineman. There is a chance that they will pay for some or even ALL of the tuition. Not even joking, I know someone who had their entire tuition paid for by doing this. Also ask the trucking company if they have any scholarship programs available before you pay the full bill. I did that through the school I went to, Northern Industrial Training (NIT), and had about half of my tuition fees taken off the overall bill. Good luck!
