During what conditions should you use your low beams?

Using low beams in conditions such as rain, fog, or snow is essential because these weather phenomena can reflect light and create glare, making it difficult to see. High beams can significantly hinder visibility in these conditions as they can reflect off precipitation, causing a blinding effect not only for the driver but also for other road users. Low beams, on the other hand, provide adequate illumination of the road directly in front of the vehicle without reflecting excessively off the moisture in the air, thereby improving overall safety and visibility.

In contrast, using low beams on highways may not be necessary unless required by specific conditions, since highways typically have sufficient lighting. At night with no streetlights, high beams are generally more effective unless there are oncoming vehicles or other bright lights, which would necessitate switching to low beams to avoid blinding other drivers. Suggesting to always use low beams while driving does not take into account situations where high beams could be beneficial, such as on dark, rural roads when no other vehicles are present.
