What Does Alternating Between High and Low Beams Mean?
1 Answers
Alternating between high and low beams means flashing the headlights to alert pedestrians or other road users to be aware of the vehicle. On roads without central barriers or center lines, vehicles should switch to low beams when approaching oncoming traffic within 150 meters at night. On narrow roads, narrow bridges, or when near non-motorized vehicles, low beams should be used. Motor vehicles driving at night on roads with no streetlights, poor lighting, or in conditions of low visibility due to fog, rain, snow, dust, or hail should use low beams when following another vehicle at close range. According to Article 47 of the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China: When overtaking, motor vehicles should turn on the left turn signal in advance, alternate between high and low beams, or sound the horn. On roads without a center line or with only one lane in the same direction, when the leading vehicle receives an overtaking signal from the following vehicle, it should reduce speed and move to the right to yield if conditions permit. The following vehicle should overtake from the left side of the leading vehicle only after confirming a sufficient safe distance. After creating a necessary safe distance from the overtaken vehicle, the overtaking vehicle should turn on the right turn signal and return to the original lane. Motor vehicles should slow down and sound the horn when approaching sharp curves, hilltops, or other areas with limited visibility, as well as when overtaking or in emergency situations. Article 58: When driving at night on roads with no streetlights, poor lighting, or in conditions of low visibility due to fog, rain, snow, dust, or hail, motor vehicles should turn on headlights, position lights, and tail lights. However, high beams should not be used when following another vehicle at close range in the same direction.
