When should you switch from high-beam headlights to low beams?

• A. In any nighttime situation
• B. When there is no other traffic on the road
• C. When approaching oncoming traffic
• D. When approaching or following other vehicles

Answer: (D)

High beams help you see farther in the dark, but they also create a lot of glare for other drivers. The safest time to switch to low beams is when you’re near or behind other vehicles: when an oncoming car approaches or when you’re following someone closely. Using low beams in these situations reduces glare for them while still giving you enough light to see the road ahead. You can resume high beams only when the road is clear of other traffic.
