In which situation should you avoid using high beams?

• A. On unfamiliar roads
• B. In construction areas
• C. When there may be people along the side of the road
• D. In fog, snow, or heavy rain

Answer: (D)

High beams are great for very dark, open roads, but they create a lot of glare that can be harmful to your ability to see in certain conditions. In fog, snow, or heavy rain, light from high beams bounces off the droplets or flakes and back into your eyes, turning the road into a bright haze and making it harder to judge distance or spot hazards. Switching to low beams cuts through the precipitation more effectively and reduces glare, giving you a clearer view of the road ahead and making it safer for everyone around you.

In other situations, like when you’re on unfamiliar roads, in construction areas, or where there may be people along the side of the road, you still want to be mindful about glare and use low beams when appropriate, but the weather-driven glare is the clearest reason to avoid high beams in this scenario.
