What Does It Indicate When the Illumination Distance of Vehicle Lights Changes from Far to Near at Night?

[IsabelaDella]

When driving a vehicle to the top of a slope at night, the illumination distance of the lights does not change from far to near, but from near to far. Below are specific hazards of indiscriminate use of high beams while driving: Instant Blindness: During nighttime encounters, the dazzling light from high beams can cause temporary blindness to oncoming drivers. The duration of this blindness varies depending on the driver's own vision and the surrounding environment, lasting around 2 seconds, significantly reducing the ability to observe pedestrians and vehicles ahead and behind. Inability to Observe Through Rearview Mirrors When Rear Vehicles Use High Beams: When a vehicle behind turns on high beams, large areas of glare appear in all three rearview mirrors of the vehicle in front. The glare in the front three mirrors reduces the visible range of the road conditions ahead.
