Adults can’t be fined for not wearing a helmet in Georgia because the law states helmets are not required if a rider is 16 or older. You must wear a helmet if you are under 16, though you won’t be criminally penalized even if you violate the law. However, you could get your parents into legal trouble. Your parents are obligated to ensure that you abide by Georgia’s bike helmet rule. If you violate the law, they could be charged with a misdemeanor.
