What are the regulations for light usage?

[MacAshlyn]

Light usage regulations include: 1. Turn signals: Turn signals should be activated 100 to 50 meters in advance when turning, changing lanes, overtaking, making a U-turn, or pulling over to park. 2. Low beam headlights: On roads without central barriers or center lines, low beams should be switched on when meeting another vehicle at night, maintaining a distance of at least 150 meters from the oncoming vehicle. Low beams should also be used when meeting non-motorized vehicles on narrow roads or bridges. 3. High and low beam headlights: When driving at night through sharp curves, slopes, arched bridges, pedestrian crossings, or intersections without traffic signals, vehicles should alternately use high and low beam headlights.
