What is the effect of looking at the right side of the road lines at night?

Answer: B — To avoid headlight glare

Looking at the right side of the road lines at night helps to avoid headlight glare. When driving at night, especially if you have oncoming traffic, focusing on the right edge of the road can reduce the effect of bright headlights from other vehicles. This technique guides your attention away from the blinding lights and helps you maintain a clearer vision of your path, enhancing safety during nighttime driving. While maintaining lane position, navigating curves, and following road signs are important aspects of safe driving, they are not the primary benefits of focusing on the right side of the road at night. Instead, the primary focus in such situations is on minimizing distractions and enhancing visibility through glare reduction.
