High Beam or Low Beam on Highways?

[DeFernando]

Use high beams on highways, but switch to low beams when the distance to the preceding vehicle is within 100 meters. Highway streetlights are not densely distributed, resulting in poor visibility. The illumination range of low beams is about 30 meters, which can easily lead to accidents. In contrast, high beams have a longer illumination range of approximately 100 meters, providing sufficient distance to handle sudden situations. During extreme weather conditions, use lights cautiously. In heavy fog, for instance, high beams can cause light scattering, making it impossible to see anything in front of the car. In such cases, the appropriate action is to proceed slowly with low beams.
