Turning 18 removes the minor-only GDL progression requirements that otherwise govern the next licensing stage, but it does not convert an instruction permit into an unrestricted Operator's License. If you are still driving under an instruction permit, continue following that permit's supervision rules until you obtain the full license.
Your instruction permit after turning 18 remains subject to its printed expiration date. Once you are 18, you can pursue an Operator's License under the adult testing requirements without completing the minor restricted-permit progression.
At 18, the restrictions tied specifically to the Restricted Minor's Permit no longer apply, but the separate Instruction Permit supervision rule does not disappear merely because the holder turns 18.
Can you drive alone as soon as you turn 18 if you still only have an instruction permit? No. Turning 18 changes the minor licensing progression, but it does not turn an instruction permit into an Operator's License. Continue driving with the required supervisor until the full license is issued.
South Dakota's age-18 statute voids restrictions attached to the restricted-minor-permit sections, while SDCL 32-12-11 separately sets the supervision rules for an instruction permit.
After turning 18, you may apply for an Operator's License under the adult requirements. You do not need to complete the Restricted Minor's Permit stage or the teen supervised-driving log before applying.
Adults 18 and older can skip the instruction permit entirely by taking both tests on the same day. If you fail the road test, a permit issues automatically to allow continued supervised practice.

"The AI mock tests were surprisingly realistic. The explanations for road signs helped me understand the logic, not just memorize. Passed my permit test on the first try!"

"I was struggling with the specific road rules of my state until I used Shoro. The flashcards are a game changer for quick revision before the actual exam."

"The readiness score gives you so much confidence. I knew exactly when I was ready to take the test. Highly recommend Shoro for anyone nervous about their exam."
