Key Administrative Checkpoints & Rules

New South Dakota residents generally have 90 days to obtain a driver's license

South Dakota generally allows a new resident to use a valid out-of-state driver's license for 90 days before obtaining a South Dakota license.

Written and road tests are not automatically required for every transfer

South Dakota's standard licensing process includes vision, knowledge, and driving tests, but a transfer from another state can follow a different process. Testing requirements depend on the applicant's existing credential and circumstances.

Foreign-license rules should not be confused with U.S. license transfers

A foreign driver's license does not automatically create the same transfer treatment as a U.S. state license. Non-U.S. citizens must follow South Dakota's applicable licensing and documentation rules.

South Dakota gives residents 90 days to title and license an out-of-state vehicle

The South Dakota Department of Revenue states that a person moving from another state has 90 days from arrival to title and license the vehicle in South Dakota.

South Dakota has no individual income tax

South Dakota is one of the states without a personal individual income tax. Federal income-tax obligations continue to apply.

Motor vehicles are subject to a 4% excise tax

South Dakota generally imposes a 4% motor-vehicle excise tax on the purchase of cars, trucks, vans, and other qualifying motor vehicles. This is separate from the state's general sales/use tax.

School vaccine requirements include kindergarten and 6th-grade checkpoints

South Dakota generally requires four DTaP-family doses, four polio doses, two MMR doses, and two varicella doses for kindergarten through 12th grade, with Tdap and meningococcal requirements tied to 6th-grade entry.

Driver Licensing Guidelines

South Dakota Driver License for New Residents

A person moving to South Dakota generally has 90 days to obtain a South Dakota driver's license. The new resident must apply at a South Dakota Driver Licensing location and provide the required documentation.

Out-of-State License Transfers

A person transferring an existing state-issued license generally must surrender the previous credential. Depending on the transfer, the applicant may not need to repeat all written and driving examinations.

Standard Testing

For a standard new license, South Dakota requires a vision test, knowledge test, and driving test. Knowledge and driving tests have an 80% passing score, and the applicant generally provides the vehicle used for the road test.

Foreign License Holders

Foreign-license holders should not assume that a foreign license receives the same testing waiver as a current U.S. state license. Non-U.S. citizens must also provide the identity and lawful-status documents required by South Dakota.

Legal Presence and Residency Documents

New applicants, transfers from another state, and non-U.S. citizens must provide accepted proof of lawful status and two documents establishing a physical South Dakota residential address. Documents must generally be original or certified copies.

REAL ID

South Dakota offers federally compliant REAL ID credentials. Applicants must provide the additional identity, Social Security, lawful-status, and residential-address documentation required for the federally compliant credential.

Frequently Asked Questions

A valid foreign license can be used while meeting South Dakota's applicable nonresident rules, but becoming a South Dakota resident requires obtaining a South Dakota credential. Foreign-license holders should not assume the same test waiver available to every qualifying U.S. state transfer.
