The laser beam on the highway reminds drivers to pay attention to safety when driving at night.

In fact, green laser can be called "anti-fatigue laser light", which is used to remind drivers to pay attention to safety when driving at night and prevent drivers from driving fatigued.

These laser lights will stimulate the driver's visual nerves through changes, thus achieving a refreshing effect. Its beam irradiation distance is long (range up to 2 kilometers), and it is generally set up on straight sections of the road. The green laser is particularly visible at night and has two forms: constant light and stroboscopic, which can effectively stimulate the driver's brain and play an anti-fatigue role.

Because when driving on a highway, the road is generally relatively smooth, and the drivers only use a single action, which is to fine-tune the steering wheel. This is fine for a short time, but it is easy to become sleepy for a long time. In fact, there is not only this kind of refreshing equipment on the highway, strobe lights and reflective tapes also have such a role.

Remedies for feeling sleepy on the highway

1. Listen to novels. Not only is it easy to feel sleepy while driving on the highway, it is also boring. Listening to music alone can become a bit monotonous. Then you can download the audio version of your favorite novel on your phone before departure. Listening to it while driving will definitely prevent you from dozing off and making you sleepy. This is because your attention is always focused on the development of the plot of the novel, and you have no time to think about sleeping. And you will feel that the journey is not so boring.

2. Bring family and friends. Because family and friends can chat with you in the car, even if you can't find a topic, it doesn't matter, just keep talking to you. Because people will never feel sleepy when talking, and they can also take this opportunity to talk to their family and friends about their innermost feelings and enhance their relationship. It can be said that it kills two birds with one stone. But here you need to warn your family and friends in advance not to fall asleep in the car, because this is more likely to cause the driver to doze off.

3. Sing. If you are really sleepy while driving on the highway and want to sleep, but you are still some distance from the nearest service area. You can sing loudly to the music in the car, and don’t be afraid of not singing well. Because no one can hear you except yourself, and no one will pay attention to what you are doing in the car. So singing when you are sleepy not only refreshes your mind but also allows you to practice your singing voice.
