What does the green laser light on the highway mean?

Highway green laser lights are anti-fatigue laser lights used to remind drivers to pay attention to safety during night driving. These laser beams have a long projection distance, with a range of up to 2 kilometers, and are generally installed on straight road sections. The green laser is particularly noticeable at night and comes in two forms: constant light and strobe light, which can effectively stimulate the driver's brain and serve an anti-fatigue function. Green laser lights can alleviate visual fatigue caused by monotonous driving environments through light variations, and they are installed only after multiple on-site surveys and concentrated demonstrations. The green laser lights form a beam network in the air in the direction of oncoming traffic without obstructing the driver's view. Together with flashing lights and high-decibel alarms, they create a trinity of visual, auditory, and photoelectric warning functions, enhancing driving safety awareness, with particularly noticeable effects during night driving and in adverse weather conditions such as rain, snow, and fog.
I often drive on highways at night, and those green laser lights are actually designed to prevent driver fatigue. The flashing green lights are quite eye-catching and stimulating, helping to keep your eyes alert. You know, especially during long-distance driving, losing focus is common, and these beams really help to refresh your mind. I think they use green light because it has strong penetration, making it clearly visible at night without straining the eyes. When I encounter them, I slow down a bit to ensure the car stays steady. Sometimes they're installed before curves or construction zones to warn of hazardous sections. I think this design is very thoughtful—highway management departments are making efforts to reduce accidents and enhance safety. If you see green lights while driving at night, don’t panic; just drive normally but stay more alert. If you're feeling tired, it’s best to pull into a service area and take a break. Remember, safe driving is the priority, and these small measures can save lives.
