What should drivers remember about auxiliary driving lights when approaching another vehicle?

When approaching another vehicle, drivers should remember that auxiliary driving lights should be turned off when the headlights dim. This is important for ensuring the safety and comfort of other drivers on the road. High beams or bright auxiliary lights can cause glare and impair the vision of oncoming drivers, making it difficult for them to see. By turning off these lights or dimming them when another vehicle approaches, drivers contribute to safer driving conditions for everyone.

The other options do not align with safe driving practices. Keeping auxiliary lights on at all times or using them only in fog can lead to visibility issues for other motorists. Additionally, while auxiliary lights can enhance visibility in certain situations, they are not necessary for all driving conditions. Proper use of lighting is crucial in maintaining safety on the roads.
