The correct distance for using low beam headlights when approaching oncoming traffic is 150 meters. This guideline is in place to prevent glare that can obstruct the vision of other drivers, ensuring safety for everyone on the road. High beam headlights can be blinding, and switching to low beams within this distance helps maintain visibility for both drivers while reducing potential hazards. Using your low beams within 150 meters ensures compliance with road safety laws and helps facilitate safer driving conditions in various scenarios. It's beneficial for creating a sensible standard to follow, as greater distances could lead to irresponsible use of high beams, compromising the safety of oncoming traffic.
