What lights to use when driving closely behind another vehicle?

[SanRobert]

When driving closely behind another vehicle, use low beam lights. Below are the regulations for using lights during nighttime driving: 1. Do not use high beam lights: When meeting vehicles on roads without central separation facilities or center lines, high beams must not be used within 150 meters of oncoming traffic; when meeting non-motorized vehicles on narrow bridges, narrow roads without central separation facilities or center lines, high beams must not be used; when driving at night on roads without streetlights, poor lighting, or in conditions of low visibility such as fog, rain, snow, or dust, high beams must not be used when following another vehicle closely in the same direction. 2. Alternate between high and low beam lights: When passing sharp curves, slopes, arched bridges, crosswalks, or intersections without traffic signals, alternate between high and low beam lights to signal.
