Should You Use High Beam or Low Beam in Highway Tunnels?

[MacHannah]

When entering a tunnel on the highway, you should use low beam headlights. If there is no lighting inside the tunnel, you should alternately use high and low beams to signal. Here is more information about turning on car lights after entering a tunnel: Position Lights (Marker Lights): Because the light outside the tunnel during the day is intense and glaring, while the light inside the tunnel is relatively dim, there is a period of eye adaptation when entering the tunnel. During this process, drivers can easily misjudge road conditions. Turning on the lights helps drivers observe the road and alerts other vehicles. Low Beam Headlights: You should turn on low beam headlights when entering a tunnel. They provide close-range illumination, allowing you to see other vehicles and the conditions inside the tunnel clearly. They also make your vehicle visible to those behind you. Driving in a tunnel without lights poses certain safety risks.
