Should the low beam be turned up or down?

[DelJohnny]

The low beam is turned up. Below are specific details about the low beam of motor vehicles: 1. Usage: The high beam of a car is generally suitable for use when driving at night on roads without streetlights or with poor lighting, such as on dimly lit national highways or expressways. In urban areas where lighting is good, the low beam must be used. 2. Relevant lighting regulations: When driving at night without streetlights and under poor lighting conditions, turn on the high beam; when following another vehicle closely in the same direction at night, turn on the low beam; when passing over an arch bridge or a crosswalk at night, alternate between low and high beams; when passing through an intersection without traffic signals at night, alternate between low and high beams; when navigating sharp curves or slopes at night, flash the low and high beams twice consecutively; when driving in foggy conditions, turn on the small lights, fog lights, and hazard lights.
