What are the laser lights on highways used for?

Laser lights on highways are primarily used for warning purposes. The green laser lights help prevent fatigued driving, and with their high brightness and long range, they effectively stimulate the brain of drivers who travel for long hours at night, helping them stay alert. Here are some related details: 1. Highways often have straight roads with few reference points, making driving monotonous. Prolonged driving can easily lead to drowsiness, especially for truck drivers on long nighttime journeys, increasing the risk of fatigued driving. 2. Green laser lights are installed to stimulate the senses through light. Traffic police typically conduct multiple surveys to position these lights in areas prone to fatigued driving, usually on relatively straight sections. The brightness is adjusted to an appropriate level—providing visual impact without obstructing the driver's view. 3. Laser lights come in two forms: continuous and flashing. Besides laser lights, strobe lights and reflective strips also serve anti-fatigue purposes. The main goal is to enhance drivers' awareness, ensuring they take adequate rest to avoid traffic accidents.
