How many hours of practice driving time are required with an adult for a learner's permit holder?

A learner's permit holder is required to complete 45 hours of practice driving time with an adult who is at least 21 years old. This requirement is designed to ensure that new drivers gain sufficient driving experience in various conditions and scenarios under the supervision of a more experienced driver. The 45 hours of practice should include at least 15 hours of nighttime driving, providing the learner with exposure to different aspects of driving, including handling the vehicle in less-than-ideal visibility. This structured practice helps build the learner's confidence and competence behind the wheel, which is essential for safe driving habits in the future.
