What lights should be turned on when a vehicle enters a tunnel?

[Jaxson]

When driving into a tunnel, you should turn on the headlights. Here are some relevant introductions about driving into a tunnel: 1. Pay attention to warning signs before entering the tunnel: There are traffic signs indicating width and height restrictions in front of the tunnel. You must clearly see the warning signs and drive in compliance with the regulations. Warning signs are scientifically calculated, so you must believe that following the instructions will not cause any problems. If you are careless and ignore them, you will have to bear the consequences. 2. Slow down and turn on the lights before entering the tunnel: If you are driving during the day, the light will suddenly dim when entering the tunnel, and the human eye often takes a short time to adapt. Therefore, you should reduce your speed, increase the distance between vehicles, and turn on the headlights before entering the tunnel to safely enter the tunnel at a relatively slow speed. Generally, tunnels have clear speed limit signs, and you can drive according to the speed limit prompts before the tunnel.
