What are the green lasers on the highway used for?

[Hector]

The row of green laser lights on the highway are anti-fatigue laser lights. The purpose of turning on anti-fatigue laser lights on the highway at night is to remind drivers to stay alert and avoid fatigued driving. Here is some relevant information: 1. These green laser beams have a long irradiation distance and are particularly noticeable at night. The laser lights come in two forms: constant-on and strobe, with a range of 2 kilometers, which can effectively stimulate the driver's brain and use this method to avoid fatigue. These lasers are generally only installed on relatively straight sections of the road. 2. The installation of anti-fatigue laser lights on the highway can provide visual stimulation through changes in light, thereby altering the visual fatigue caused by monotonous driving conditions. After multiple on-site surveys and concentrated discussions, highway traffic police have placed the laser lights on relatively straight sections of the road that are prone to fatigued driving, adjusting the lasers to ensure sufficient brightness while also providing a certain visual impact to effectively prevent drivers from fatigued driving. Anti-fatigue laser lights are just one of the many anti-fatigue measures implemented by highway traffic police.
