Noob post (help me out, please)

[agogo]

I don't know if this is very relevant to this forum but I really have no idea where else I can find information on this. I do think that people here might have an answer, though.

I am currently about to get my class G1 (regular CAR driving) license (I am canadian). In a year, I will be able to have a G2 license, which will allow me to drive alone and on highways.

At that point, i have planned to go on a road trip in america. Alone. I would have a year off after highschool and it would be a great time to do this.

I just want to know:

What issues might i have at the border?

And what response would i get if i were stopped in america, and had a Canadian license?

Thanks in advance, and sorry if this doesn't belong here.
