A person younger than how many years of age operating an all-terrain vehicle on public property must be under direct supervision?

The correct answer indicates that individuals younger than 14 years of age must operate an all-terrain vehicle (ATV) on public property under the direct supervision of an adult. This regulation is in place primarily for safety reasons, as younger operators may lack the maturity and experience needed to handle these vehicles safely, especially in public environments where there may be increased risks from other motorists or obstacles. By requiring adult supervision for those under 14, authorities aim to ensure that young operators are guided and monitored, thereby reducing the likelihood of accidents and promoting responsible ATC use.
