When should you use low beams while driving?

Using low beams in the presence of other vehicles is important to ensure safety and prevent blinding other drivers. High beams can create significant glare for oncoming traffic and for vehicles you are following, which can make it difficult for them to see the road. Low beams are specifically designed to provide adequate illumination of the road ahead while minimizing the brightness that can affect other drivers' vision.

In situations with other vehicles, low beams help maintain good visibility without compromising the safety of others on the road. This is a common practice at night or in conditions of reduced visibility, such as rain or fog, where the light from high beams reflects off moisture in the air, further obstructing visibility.

In contrast, using low beams only during daytime or exclusively in foggy conditions isn’t as broadly applicable, as low beams are also necessary when driving at night or in the presence of other vehicles at any time. Therefore, it's crucial to use low beams in any scenario where nearby drivers could be affected by your vehicle's headlights.
