What lights should be turned on when entering a tunnel?

Use low beam lights when passing through a tunnel. Here is some relevant information about low beam lights: 1. Definition: Low beam lights are designed for close-range illumination, with a wide coverage angle (160°) and a short projection distance, and the focus cannot be adjusted. 2. Situations requiring low beam lights: When driving in areas without streetlights at night, or during dusk when it's dark or dawn when light is just appearing, low beam lights must be turned on; if encountering heavy fog, snow, or heavy rain that obstructs visibility, low beam lights must be turned on even during the day; on some roads where lighting is insufficient despite having lighting equipment, low beam lights should also be turned on.
Every time I drive into a tunnel, I immediately turn on my low beams—it's a crucial safe driving habit. The dim lighting in tunnels means you can't see the road clearly without headlights, and other drivers might not spot your car, increasing the risk of rear-end collisions or sideswipes. I once tried entering a tunnel without lights and instantly struggled to adjust to the darkness, panicking so badly that I wobbled the steering wheel. The law requires low beams in tunnels since high beams can dazzle oncoming drivers and cause accidents. On rainy days, tunnels become even slicker, and low beams illuminate the road 10+ meters ahead, helping maintain steady speed. Another detail: many tunnel entrances have automatic cameras monitoring headlight usage—skipping them could mean a ticket. Make it a habit to slow down and activate lights before fully entering, not waiting until plunged into darkness. A simple step for safety.
