After how many driving hours must at least 10 hours be completed after sunset?

The requirement to complete at least 10 hours of driving after sunset as part of the overall driving hours reflects the importance of gaining experience in varied driving conditions, particularly at night. Night driving presents different challenges compared to daytime driving, such as reduced visibility, the presence of headlights from oncoming traffic, and the potential for increased fatigue.

The total requirement sets a minimum of 40 hours of supervised driving, of which at least 10 hours must occur during nighttime hours. This ensures that new drivers develop confidence and competence on the road in less optimal conditions, which is critical for safety. Meeting this specific nighttime driving experience is essential for preparing new drivers to handle real-world scenarios once they are fully licensed.

Therefore, the correct response underscores the structured approach to ensuring that new drivers are adequately prepared to drive safely at all times, particularly during the more challenging night driving.
