Umm at 16 you can get g1 which means someone who has had a G for more then 4 years you can drive with. + the person with the G has to be in the passenger seat. Trust me.. not that great ;). G2 is when you can drive by yourself anytime.. but cant drive like trucks and stuff like that only cars. You also cant have ANY alcohol. When you get your G you can drive anywhere , blah blah blah, and have a blood alcohol of .5. ^ lol. Sorry for breaking your sweet sixteen dreams. Its more like sweet 18.
