What is the standard illumination distance for car low beams?

[AlessandraAnn]

Car low beams typically have a standard illumination distance of approximately 30-40 meters, with the beam cutoff line around 12-18 meters. If the illumination distance is too short, the visibility at night will be reduced, which is detrimental to driving safety. Precautions for using car lights: When driving at night with streetlights on, or in conditions of low visibility such as fog, rain, snow, dust, or hail, the headlights, position lights, and tail lights should be turned on. On roads without central barriers or centerlines, when meeting another vehicle at night, switch to low beams when the oncoming vehicle is more than 150 meters away. Additionally, low beams should also be used when meeting non-motorized vehicles on narrow roads or bridges. If a vehicle breaks down or is involved in an accident on the road, obstructing traffic and making it difficult to move, the hazard warning lights should be activated, and a warning sign should be placed 50 to 100 meters behind the vehicle. At night, the position lights and tail lights should also be turned on simultaneously.
