What Are the Green Lasers on Highways?
1 Answers
Highway green lasers are called "anti-fatigue laser lights," designed to alert drivers for safety during nighttime driving. These lasers have a long beam projection distance (up to 2 kilometers) and are typically installed on straight road sections. The green lasers are particularly noticeable at night, available in both steady and flashing modes, effectively stimulating the driver's brain to counteract fatigue. Introduction to Anti-Fatigue Laser Lights: These laser lights can be freely adjusted in angle without obstructing the driver's view, creating a beam network in the air toward incoming traffic. They integrate laser, strobe, and high-decibel alarm functions for a tri-sensory (light, sound, and electrical) warning effect. The system aims to "stimulate" drowsy eyes through changes in light and sound, alleviating visual fatigue caused by monotonous driving conditions. By providing sensory stimulation to drivers, it enhances their safety awareness when passing through accident-prone areas, especially under adverse weather conditions like night, rain, snow, or fog. Subjectively, it significantly reduces driving risks and accident rates. Currently, anti-fatigue laser lights have been installed on highways in Shandong, Shanxi, Henan, Hebei, Shaanxi, Jiangsu, and other provinces. Wuxi traffic police reported a 17% decrease in fatigue-related accidents at system-equipped accident-prone sections. The "anti-fatigue laser light" is merely a technological "reminder" measure for accident prevention. Avoiding fatigued driving fundamentally requires personal responsibility: ensure sufficient sleep, avoid driving during afternoon and nighttime hours when possible. Schedule driving time scientifically—continuous driving should not exceed 4 hours, with breaks lasting at least 20 minutes. Nighttime continuous driving should be limited to 2 hours maximum, preferably with two drivers taking turns. Arrange rest periods properly; avoid maintaining a fixed posture for extended periods while driving. If feeling drowsy, exit at the nearest service area or highway exit for rest.
