Rules for teen drivers: While South Dakota allows minors as young as 14 to get a learner's permit, those drivers cannot apply for a full operator's permit until age 16.
Cancellations and nonrenewals: Your policy can be canceled midterm only because of nonpayment or you have lost your driving privileges. If an insurance company chooses not to renew your policy, it must give you 60 days' notice.
