States require applicants for drivers’ licenses to be at least 16 years of age. In many states, if applicants are younger than 18, they must also provide a signed parental authorization form. This form states a person’s relationship to the applicant for a license and gives permission for the person to acquire a driver’s license.
Usually, states will require that the parental authorization form be notarized or signed in the presence of the proper authority at a licensing facility. Whenever individuals present themselves for a driver’s examination, they must provide proof of their identification and age. This can be done with an official document such as a birth certificate or passport.
