7 tracks across Ohio have real evidence of children driving — junior karts, family sessions or a published minimum age — rather than just an arcade next to an adults-only track. They're spread across 2 metro areas, so most of the state is within a reasonable drive of one.
Height governs more than age at most venues: the lowest published requirement among these tracks is 48 inches, and the lowest published minimum age is 8. Requirements differ by kart class, so check the individual track page and call ahead if your child is near the cutoff.
