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.
