How old do you have to be to get your own car insurance?

I'm 16 and I recently started driving. I own my own car but I do not have insurance. My parents do not have insurance and my mom siad that for me to be covered she would have to get insurance on all the drivers in the house on all the vehicles. She said I could pay it I'd like but that it would be about $300 a month.

Is it possible for me to get MY OWN coverage and not have to pay for the rest of the family.
