Under what conditions should you not use your high beam headlights?

High beam headlights are designed to illuminate the road further ahead than low beams, making them useful in certain driving situations. However, they can cause significant glare for other drivers. When there is oncoming traffic or when you are driving behind another vehicle, the use of high beams can impair the vision of those drivers, increasing the risk of accidents. Therefore, it is important to switch to low beams to ensure safety for everyone on the road.

In contrast, there are circumstances, such as driving on highways or driving alone at night, where high beams might be appropriate because there are fewer or no other vehicles to cause glare issues. However, using high beams in fog can lead to reduced visibility, as the light can reflect off the fog, making it harder to see through. Each of these situations calls for an understanding of when to appropriately use headlight settings for safe driving.
