At what distance should you switch to low beam when facing oncoming vehicles?

When driving at night, you should switch to low beam when the distance to the oncoming vehicle is within 150 meters. Here is some relevant information about adjusting car lights: 1. Adjustment of low beam: The adjustment of vehicle lights usually involves the left-right and height alignment of the low beam. This can be done using the knobs located at the rear of the headlight assembly, and car owners can adjust the lights themselves with the appropriate tools. 2. Headlight adjustment: Lift the engine hood and locate the adjustment knobs at the rear of the headlight assembly. Use the corresponding tools to make adjustments. Before adjusting, determine whether the knob controls left-right or up-down alignment. Park the vehicle directly facing a wall at a distance of about 10 meters, observe the height of the left and right lights, and use tape or other markers for measurement and comparison if necessary, then proceed with the adjustment.
After driving for so many years, I clearly remember that when the lights of oncoming vehicles start to reflect noticeably, the distance is about 150 meters. At this point, you must switch to low beams. Otherwise, the glare can temporarily blind the other driver, significantly increasing the risk of a collision. When driving at night in rural areas or on mountain roads, experience tells me that 150 meters is a safe threshold. Headlight designs allow high beams to cover greater distances, but switching when approaching can prevent accidents. It’s important to develop this habit, especially in poor visibility conditions, acting in advance to ensure everyone’s safety. Since adopting this good habit, I’ve never had issues with headlight glare. Safety is no small matter—simple rules can save lives, so don’t wait for an accident to regret it.
I just learned to drive not long ago, and the instructor repeatedly emphasized that you must switch to low beams when oncoming vehicles are 150 to 200 meters away. High beams can dazzle the other driver, making it hard for them to see the road clearly and potentially causing serious accidents. Normally, I judge the distance by observing the reflection of the headlights and immediately switch beams when it's about 150 meters. City roads with ample lighting may not require high beams, but they are crucial in suburban areas and on highways. Remembering this distance not only prevents accidents but also avoids traffic fines. It's recommended for beginners to practice and get used to it—light control is a fundamental skill, and staying alert while driving is key. Simple rules like this can enhance overall safety.
