These Laser Lightshows on Chinese Highway Are Meant to Keep Drivers Awake

Chinese road officials have introduced laser light shows on the Qingdao–Yinchuan Expressway to combat nighttime driver fatigue. The lasers, mounted on sign gantries, project vibrant red, blue, and green lights above the highway, creating a surreal visual experience intended to keep drivers alert. While the lights are designed to be non-distracting and do not strobe or aim directly at vehicles, they have sparked discussions about their effectiveness. A user on social media shared a video showcasing the lights, noting that they helped alleviate his exhaustion during a long drive.

This initiative is part of a broader trend to enhance driver engagement on monotonous stretches of road. Similar efforts have been observed in other countries, such as Australia, where trivia questions are displayed on roadside signs to keep drivers mentally stimulated. However, experts caution that the best way to avoid fatigue is to refrain from driving when tired. The National Highway Traffic Safety Administration warns that relying on caffeinated drinks can lead to a false sense of security, potentially resulting in dangerous "microsleeps." Overall, while the laser displays may provide a temporary boost in alertness, they are not a substitute for proper rest before driving.
