Is it legal to drive with a learner's permit alone?

Driving with a learner's permit requires specific conditions to ensure safety and compliance with the law. The correct answer emphasizes the necessity of having a licensed adult present while driving. This regulation is in place to provide new drivers with guidance and support as they gain experience behind the wheel. The presence of a licensed adult helps ensure that safety protocols are adhered to and that any necessary instruction can be provided in real-time when needed.

In contrast, the other options suggest scenarios which are not aligned with typical learner's permit regulations. For instance, having just a valid ID or being over 18 does not exempt a learner from needing a supervising licensed driver. The law is designed to protect both the learner driver and others on the road, reinforcing the importance of having an experienced driver alongside.
