During what hours can a holder of a learner's permit drive without supervision?

Answer: C — They cannot drive unsupervised

The correct understanding regarding the driving restrictions placed on a holder of a learner's permit is that they cannot drive unsupervised. This is a safety measure to ensure that novice drivers are still under the guidance of someone who has more experience and can help them navigate various driving situations. While the various options hint at different allowances for unsupervised driving, the regulation clearly states that a learner's permit does not permit independent driving. This ensures that learners practice safe driving habits under supervision, which is crucial for their development as responsible drivers.
