Under what condition should you use your high beam headlights?

Using your high beam headlights is appropriate on dark roads when there is no oncoming traffic. High beams provide a brighter and more expansive illumination, allowing drivers to see further into the distance, which is particularly beneficial on poorly lit roads. This extended visibility can help in spotting pedestrians, animals, or any potential hazards more effectively.

In contrast, using high beams in foggy conditions can lead to reduced visibility, as the light reflects off the water droplets in the fog, creating a glare. This can make it more difficult to see the road ahead clearly. Similarly, using high beams when there is oncoming traffic can blind other drivers, creating a dangerous situation for everyone on the road. Lastly, high beams are generally not used in city traffic where streetlights provide adequate illumination, and where there are more vehicles and pedestrians that may be affected by the glare of high beams.
