Blue laser lights activated on highways at night serve as anti-fatigue laser lights to remind drivers to stay alert and avoid drowsy driving. Below are some precautions for highway driving: 1. Take breaks: Ensure adequate rest both before and during the journey. Get sufficient sleep before driving to prepare for the trip. If you feel sleepy while driving, pull over at a service area for a short break—never push through drowsiness. 2. Maintain distance: High-speed driving can affect a driver's vision and reaction time, so it's crucial to keep a safe following distance to ensure adequate braking distance. 3. Pre-drive vehicle check: Before setting off, conduct a thorough inspection of your car's lights, engine oil, coolant, tire pressure, etc., to prevent malfunctions during the journey.
The blue laser lights on highways are actually designed to enhance driving safety, especially during nighttime driving. When I was driving, I noticed that these lights are usually installed on the shoulder or overhead, serving to alert drivers not to deviate from their lanes. The laser projections form dots or lines, aiding navigation in low-visibility conditions. For example, during foggy or rainy weather when ordinary lights are hard to see, the strong penetrating power of blue lasers ensures stable visibility. They also integrate with other smart systems, such as vehicle-to-everything (V2X) communication, to monitor traffic flow in real-time and prevent accidents. I think this is pretty cool—it leverages modern technology to make travel safer and reduces the risk of fatigued driving, making it suitable for people of all ages.
