What is the purpose of the laser lights on highways?

Warning function. The green laser lights can prevent fatigue driving with their high brightness and long range. For drivers who drive for long periods at night, they effectively stimulate the brain to stay alert. Additional information is as follows: 1. Highways have fewer reference objects due to their flat and straight roads, leading to monotonous driving actions that can easily cause drowsiness, especially in summer. Green laser lights are set up to stimulate the senses through light. 2. After multiple inspections, traffic police have placed these lights in areas prone to fatigue driving, typically on relatively straight road sections. The brightness is adjusted to an appropriate level to create a visual impact without affecting the driver's vision. Laser lights come in two forms: constant-on and strobe. 3. In addition to laser lights, there are also flashing lights and reflective strips that serve anti-fatigue purposes, enhancing drivers' awareness and ensuring sufficient rest time to prevent traffic accidents.
When I used to drive long distances, I often saw those laser lights on the highway, especially in foggy conditions or at night, and they played a crucial role. They are primarily used for safety warnings, such as when a vehicle breaks down, at accident scenes, or in construction zones—the laser beams light up with bright colors and strong penetration, allowing drivers to notice hazards from afar. Additionally, many places use them in conjunction with monitoring systems for speed detection, emitting laser beams to scan vehicles and accurately relay speed data back to the control center, helping traffic police enforce laws and reduce accidents caused by speeding. I remember one heavy fog day when these lights helped me avoid an obstacle ahead, preventing a rear-end collision. Overall, they represent the intelligence of traffic management, enhancing driving safety, but their installation locations must be chosen carefully to avoid mistakenly interfering with other equipment and causing maintenance issues.
