What Lights Should Be Turned On When Driving Through a Tunnel?

[VonMatthew]

When entering a tunnel, the car's headlights should be turned on. This allows for better visibility of the road conditions ahead. Below are some relevant details about driving through tunnels: Observe warning signs before entering the tunnel: Tunnels usually have traffic signs indicating width and height restrictions. Make sure to read these warning signs carefully and drive accordingly. Reduce speed and turn on lights before entering the tunnel: If driving during the day, the light will suddenly dim upon entering the tunnel, and the human eye may take a short while to adjust. Therefore, before entering the tunnel, you should reduce speed, increase the following distance, and turn on the headlights to enter the tunnel safely at a relatively slower speed. Most tunnels have clear speed limit signs, so you can follow the speed limit indicated before the tunnel.
