Ride Atv Georgia

Where and how I can know if there is an ATV helmet law in my county or state?
I live in Troup County, Georgia, and within limits Hogansville City. An officer told me today that my 12 year old could not ride the 4 wheeler without a helmet. He said it is a law. I understand that for security reasons should use, but I do not think it is a law. How I can know if he is?
Go to lawresearch. Com with the statutes of the state of Georgia, but be careful could be a violation of city ordinance that could cost you a fine but not a violation of state law, I would suggest calling the local council if you think the officer is misleading to talk to an employee, have access to all ordinances and state laws. ~
