So i want to be a trucker later,when im older

There was a thread on here a few days ago about a trucking game, look around and you should find it.

 

Hey Josh, best experience you could get is to ride along with another truck driver. It gives you a good idea of what he does in the truck, what his deliveries are like etc. Some companies need helpers for their drivers... when you are legally allowed to work, that may be an option until you are allowed to get your CDL.
Happy dreaming, and enjoy whatever makes you happy!
I wanted to be a trucker from before your age, and I only became on when I was 39, and it was the best thing I ever did! So do what you want to!
