Your South Dakota driver’s license stays valid past its printed expiration date while you are serving in the U.S. Armed Forces and living outside the state. It stays valid for up to 90 days after you come back to South Dakota or separate from the service. Dependents of resident service members get the same extension.
There is nothing to apply for. Carry your military ID and your orders with your license, and renew within 90 days of returning to South Dakota or separating from the service.
Your military ID and current orders showing you are stationed outside South Dakota, or proof of your relationship to the service member if you are a dependent.
