Why Are Laser Lights Installed on Highways?

[MacJasmine]

Highway roads are straight with few fixed reference points, leading to monotonous driving actions and a single line of sight for drivers. Prolonged driving under such conditions can easily cause drowsiness. This is more pronounced in summer, as the daytime heat drains physical energy. Freight drivers often undertake long-distance trips at night, making them prone to fatigue driving, which has become a key illegal activity targeted for prevention and enforcement by highway traffic authorities. Installing laser lights can alter the monotonous driving environment and mitigate visual fatigue through changes in light. After multiple rounds of concentrated discussions, highway traffic police have placed laser lights on relatively straight sections of road where fatigue driving is more likely to occur. The lasers are adjusted to ensure sufficient brightness while also providing a certain visual impact. The laser lights come in two forms: continuous and strobe, with a range of 2 kilometers.
