Glaring lasers are being used to help prevent drivers from falling asleep at the weel on a highway in eastern China.

Video filmed on Qingdao–Yinchuan Expressway on December 31, 2022, shows several colourful laser lights being shone just above the vehicles.

According to the filmer Mr Li, the anti-fatigue laser lights instantly made him feel much more energetic and less tired after he drove for a long time at night.

According to a local police officer, the anti-fatigue laser lights will not hinder the motorist's ability to drive.

10月31日早上5点多，刘先生在青银高速靠近淄博收费站的路段，沉浸式体验了一把“防疲劳激光灯幕”。他在高速行驶时忽然发现几道激光灯射向空中，醒目闪烁、色彩绚丽，瞬间觉得眼前一亮，整个人也精神了许多，在夜间长时间驾驶的自己好像也没那么困了。 山东高速交警淄博张店区一名交警回应称，这些并不是普通的灯光，而是高速交警联合运营公司投入使用的防疲劳激光灯幕。不会给驾驶员的驾驶造成阻碍。视频由刘先生提供。
