What is the purpose of the green laser on highways?
1 Answers
Highway green lasers are called "anti-fatigue laser lights," used to remind drivers to stay safe during nighttime driving. Currently, anti-fatigue laser lights have been installed on highways in multiple provinces including Shandong, Shanxi, Henan, Hebei, Shaanxi, and Jiangsu. Wuxi traffic police reported a 17% decrease in fatigue-related accidents on high-risk road sections where this system was installed. Summer is the peak season for fatigue driving. Hot weather and prolonged driving can easily lead to fatigue, especially on highways where the road environment is monotonous, traffic disruptions are minimal, and speeds are stable—all factors that can induce driver fatigue. Driving in such a state is extremely dangerous! According to incomplete statistics, fatigue-related accidents account for approximately 25% of all highway accidents and over 35% of major traffic accidents. "Anti-fatigue laser lights" are just one technological "reminder" measure to prevent accidents. Avoiding fatigue driving ultimately starts with the driver: ensure sufficient sleep, avoid driving during afternoon and nighttime hours when possible, plan driving schedules scientifically, take breaks every 4 hours of continuous driving (with rest periods lasting at least 20 minutes), limit nighttime driving to no more than 2 hours at a stretch (ideally with two drivers alternating shifts), arrange rest periods appropriately, and avoid maintaining a fixed posture for too long while driving. If drowsiness occurs while driving, pull over at a service area or the nearest exit to rest.
