Authorities in China are reportedly testing powerful laser installations on motorways in an effort to prevent drivers from falling asleep at the wheel, but drivers’ feedback has been mixed, at best.
Last year, clips of colorful light beams being projected from motorway signs in China started going viral on social media, leaving people scratching their heads about their purpose. What looks like a light show at an open-air rave is actually a trial method of preventing drivers, especially truck drivers, from falling asleep at the wheel. The most popular clip of the bizarre installation was shot on the 1,600-km-long Qingdao–Yinchuan Expressway, which is reportedly mainly used by heavy trucks from the capital city of Ningxia traveling to the port city of Qingdao.
