Using low beams in both city driving at night and in foggy or misty weather is essential for safety and visibility.

When driving at night in urban areas, low beams help illuminate the road without creating glare for other drivers or pedestrians. High beams can be excessively bright in well-lit conditions, potentially blinding oncoming traffic and making it difficult for others to see clearly.

In foggy or misty weather, low beams are preferred because they provide better visibility by reducing the amount of light that is reflected back at the driver from the fog or mist. High beams tend to bounce off these particles, creating a white wall effect that inhibits further visibility. Low beams, on the other hand, cut through the fog and illuminate the road directly ahead, improving your ability to see and be seen by other vehicles.

Choosing low beams in these scenarios not only enhances your visibility but also contributes to overall road safety, making it the advisable action in both situations.
