How many questions are on the South Dakota permit test?
The South Dakota permit knowledge test typically has 25 to 50 questions depending on the office and the version delivered on the day. To pass you need approximately 80% — that is usually 20 of 25, 32 of 40, or 40 of 50 correct. The test is delivered on a touchscreen at the SD DPS, and you generally cannot go back and change earlier answers once you advance past them.
How much does the permit cost in South Dakota?
The current South Dakota learner's permit fee is $28, payable at the counter by card, cash, or check (some South Dakota branches are card-only). If you fail the knowledge test you may be required to pay a re-test fee for each subsequent attempt; check the current fee schedule on the SD DPS website before your appointment.

How long do I have to hold the permit?
In South Dakota the supervised hold period is 6 months. During that time you must drive with a licensed adult age 21 or older in the front passenger seat. Many South Dakota counties also require 50 logged hours of supervised driving, with at least 10 of them after sunset, before you become eligible for the road test.
Can I take the test in another language?
The South Dakota permit test is offered in English and Spanish at every SD DPS office, and additional languages — typically Mandarin, Vietnamese, Korean, Tagalog, Russian, Armenian, and Punjabi — are available at major county offices and on most online versions. An interpreter you bring yourself is generally not allowed for the knowledge test.
What if I fail?
Most South Dakota counties allow you to retake the test the same day or the next business day. After three consecutive failures you may be required to wait a longer period and pay an additional fee. The SD DPS will tell you which sections you missed; spend extra time in those sections of the handbook before returning.
