Question

Fog reflects light and can reflect your own headlights into your eyes. When driving in fog you should?

1) Use low beam headlights
2) Use high beam headlights
3) Use fog lights
4) Turn on hazard lights

Answer 1

In foggy conditions, drivers should use low beam headlights or fog lights to illuminate the road without causing glare. High beam headlights should be avoided as they can reflect light back into the driver's eyes and increase glare.

Step-by-step explanation:

When driving in fog, it's important to use the right type of lighting to ensure visibility while also avoiding increased glare which can be caused by light reflecting back into the driver's eyes. The correct approach is to use low beam headlights. This is because low beams angle downward, reducing the reflection of light off the fog and thereby diminishing glare. High beams, on the other hand, shine light directly into the fog, causing more light to reflect back. Some vehicles are also equipped with fog lights, which are specifically designed to cut through fog and provide better visibility without causing glare. It's generally not advisable to use hazard lights while moving, as this could confuse other drivers into thinking your vehicle is stationary.
