How long must a learner's permit be held before obtaining a restricted license?

To obtain a restricted license after holding a learner's permit, the requirement is that the permit must be held for 180 days. This duration ensures that new drivers have enough time to practice and gain the necessary experience behind the wheel while being supervised. The extended practice period is particularly important for developing safe driving skills, understanding the rules of the road, and building confidence before transitioning to a less restricted form of driving. The other options represent durations that do not align with the established guidelines for moving from a learner's permit to a restricted license, as they either provide too little time for practice or suggest an unnecessarily long waiting period.
