How to Use Lights When Driving into a Tunnel?

[MacRichard]

Before entering a two-way tunnel, motor vehicles should use low beams instead of high beams. Generally, when entering a two-way tunnel, vehicles should turn on low beams and avoid using high beams. If the tunnel itself has no lighting, you may switch between lights as needed, but you must switch to low beams when meeting oncoming vehicles. When driving through a one-way tunnel, carefully observe whether there are oncoming vehicles and if the passage is clear before entering. If passage is permitted, sound the horn appropriately or turn on the width indicator lights, and proceed slowly. If an oncoming vehicle is entering the tunnel or a stop signal is present, promptly pull over to the right side of the entrance and wait. Only proceed into the tunnel after the oncoming vehicle has passed or a green light signal is given. Follow the rule: stop at red lights and proceed at green lights.

Using lights correctly when driving into a tunnel ensures safety. I first slow down before the tunnel entrance and promptly turn on the low beam—it illuminates the road and avoids creating blind spots for other vehicles. The sudden dimming of light inside the tunnel makes turning on the lights essential for spotting objects and road signs ahead. High beams are strictly prohibited as their reflection can dazzle oncoming drivers and cause accidents. After exiting the tunnel, don’t rush to turn off the lights; wait until your eyes adjust to the bright outside light. Once this habit is formed, the actions become instinctive every time you enter a tunnel, making driving much safer. If the car has an automatic lighting function, simply activate it; otherwise, manual operation is straightforward. Always check that the lights are functioning properly to prevent sudden failures. In short: safety first, turning on the lights is a must.

I'm a new driver, and operating the lights in tunnels is crucial. Before entering a tunnel, I make sure my speed is moderate and then turn on the low beams. I avoid using high beams as they can cause trouble. The lighting changes significantly inside tunnels, so keeping the lights on ensures both myself and others can see the road clearly. After exiting the tunnel, I wait a few seconds before turning off the lights to avoid sudden glare. This habit takes practice—I often forgot at first, but after a few trips, it became second nature. Memorizing the position of the light switch is key, and I frequently remind myself to keep my hand on the knob, ready to adjust. Safety is no small matter, and with practice, it becomes natural.

I've developed a habit of turning on my headlights when driving through tunnels. As soon as I enter a tunnel, I immediately switch on my low beams, avoiding high beams. The lights make other vehicles aware of my presence, preventing rear-end collisions. Upon exiting the tunnel, I wait a moment before turning off the lights. Simple and effective—that's the rule.
