What is the primary purpose of using low beam headlights during nighttime driving?

Using low beam headlights during nighttime driving primarily serves to avoid blinding other drivers. When vehicles are on the road at night, high beam headlights can create excessive brightness that might impair the vision of oncoming drivers. Low beam headlights are designed to cast light in a way that effectively illuminates the road immediately in front of your vehicle while minimizing glare for other road users. This is crucial for ensuring safety while driving at night, as it allows for better visibility for both the driver of the vehicle using low beams and the drivers in oncoming traffic.

While illuminating the road directly in front of the vehicle is a function of low beams, the key aspect of using them is indeed about maintaining safe driving conditions for everyone on the road without causing visual discomfort to others. The visibility of your vehicle and battery-saving concerns are secondary considerations in the context of nighttime driving safety. The primary focus remains on preventing accidents caused by impaired visibility for other drivers due to excessive glare.
