When are high-beam headlights appropriate?

• A. On dark, unlit roads with no oncoming traffic
• B. On dark, unlit roads with no oncoming traffic; switch to low beams when another vehicle approaches
• C. In fog or heavy rain
• D. On well-lit city streets

Answer: (B)

High beams are meant to give you the most visibility on very dark, unlit roads by projecting light farther down the road. But they can blind other drivers, causing a dangerous glare. Because of that, you should only use high beams when there is no oncoming traffic and you’re not within range of a vehicle ahead of you. When another vehicle approaches or you’re following at a distance, switch to low beams to reduce glare for others. In fog or heavy rain, high beams actually make visibility worse by reflecting off the moisture, so use low beams instead. On well-lit city streets, low beams are all you need. So the correct practice is to use high beams on dark, unlit roads with no oncoming traffic and switch to low beams when another vehicle approaches.
