Videos of a laser display across a Chinese highway have gone viral across various social media platforms – with overseas reports claiming it is a method tested by Chinese authorities to combat driver fatigue at night.

These highway anti-fatigue laser lights are designed to stimulate the driver's visual nerve with its strobe effect, to achieve a refreshing effect. These laser systems can generally project up to 2 km in distance and are useful for all kinds of motorists such as car drivers and truck drivers.

CHINA — Road safety authorities in China have implemented a novel solution in a bid to prevent drivers from falling asleep at the wheel at night. Called “high speed anti-fatigue laser lights”, these flashing light displays are meant to help night time drivers stay alert while on the road.

China is testing a new safety feature for its highway network. The new laser system, which they call 'anti-sleep' lasers, consists of a rainbow-colored 'sky' of lasers that go on and off at regular intervals on some sections of China's highway network. The idea is to keep drivers alert with these super colorful lasers.
