When is it appropriate to use high-beam headlights?

Using high-beam headlights is appropriate when driving in rural areas at night with no oncoming traffic because high beams provide a much brighter and broader light, enhancing visibility over longer distances in dark conditions. This is particularly important in rural settings where street lighting may be absent, allowing drivers to better see animals, pedestrians, and potential hazards on the road.

In contrast, heavy traffic during the day is not an ideal time for high beams, as they can blind other drivers and create safety risks. Similarly, using high beams during foggy conditions is ineffective because the light can reflect off the fog and reduce visibility further. Finally, in lit urban areas, standard headlights are typically sufficient, and using high beams can be disruptive to other motorists and pedestrians.
