To be considered an adult for karting purposes, you must be at least 14 years of age and be able to comfortably fit in and operate the adult kart. Also, a legal waiver must be on file or a parent must be with you.
14 years of age is a legal requirement, not a recommendation. Waivers are legal documents and if you lie about your child's age so that they can get in the adult karts it is insurance fraud. So, please do not lie or ask us to lie for you. Experience tells us that the vast majority of teens that are not, at least, 14 years of age are not ready to race in adult races.
