What should you do when you meet another vehicle while using high beams?

• A. Keep high beams on and switch lanes.
• B. Switch to low beams when encountering other vehicles.
• C. Flash high beams repeatedly to signal.
• D. Move into the opposing lane.

Answer: (B)

When you meet another vehicle, the main idea is to reduce glare by dimming your headlights. High beams help you see farther, but they can blind or dazzle the driver in front of you or approaching you, making it harder for them to see the road. Switching to low beams keeps your own visibility adequate while preventing temporary blindness for others, which helps everyone react safely.

In practice, use low beams whenever you’re near other vehicles—whether you’re approaching from ahead or following behind. Save high beams for times when you’re driving alone on dark streets with no oncoming traffic or nearby vehicles.

Flashing headlights or keeping high beams while maneuvering, or veering into the opposing lane, can confuse other drivers and create dangerous situations, so they aren’t appropriate strategies.
