The application of any person under the age of eighteen (18) years for an instruction permit or driver's license shall be signed by a parent or guardian having custody of the applicant. If there is no parent or guardian the application may be signed by the circuit court judge of the applicant's county of residence upon petition to the court and upon a finding by the court that the applicant is sufficiently mature to handle the responsibilities of driving a motor vehicle.
