Using high beams is legal and appropriate when there are no oncoming vehicles. High beams provide better visibility over long distances, making them particularly useful in dark or rural areas where there is minimal traffic. However, illuminating the road with high beams can cause glare for other drivers if they are approaching, which is why it's important to switch to low beams when another vehicle is near.

In foggy conditions, high beams can be counterproductive because they tend to reflect off the water droplets, creating a glare that further reduces visibility. In residential areas, it's generally advisable to use low beams to avoid disturbing residents and to ensure that you can clearly see pedestrians or cyclists. The notion that high beams can be used at all times is incorrect, as it does not take into account the potential hazards to other road users. Understanding these guidelines helps promote safe driving practices.
