How Far Do High Beam and Low Beam Headlights Illuminate?
1 Answers
Low beam headlights typically illuminate a distance of approximately 30-40 meters. Experiments have shown that when driving at night at a speed of 55 km/h, if a situation is detected and the brakes are immediately applied, the stopping distance is exactly 30 meters. This means that if a situation is detected within the range of low beam illumination and the vehicle is stopped immediately, there will be no gap between the vehicle and the object. Here is additional information: 1. There is no standard specifying the exact illumination distance for low beam headlights: Only the luminous intensity and beam position of headlights are regulated. However, generally speaking, low beam headlights should illuminate the area 25-35 meters ahead of the vehicle on a level road. 2. Article 48 of the Road Traffic Safety Law stipulates: On roads without central barriers or center lines, when meeting another vehicle at night, drivers should switch to low beam headlights at least 150 meters before the oncoming vehicle. Low beams should also be used when meeting non-motorized vehicles on narrow roads or bridges. When driving at night under conditions of poor visibility, such as in fog, rain, snow, dust, or frost, or when following another vehicle closely in the same direction, low beam headlights must be used. Additionally, when passing through sharp curves, slopes, arched bridges, pedestrian crossings, or intersections without traffic signals at night, drivers should alternately use high and low beams to signal.
