What lights should be turned on when driving into a tunnel?

[OSara]

When driving into a tunnel, turn on the contour lights and low beam lights. Whether it is a one-way tunnel or a two-way tunnel, do not turn on the high beam lights. In a two-way tunnel, turning on the high beam lights will affect the vision of the driver of the oncoming vehicle, while in a one-way tunnel, the high beam lights will reflect off the rearview mirror of the vehicle in front. Precautions for driving in tunnels: 1. Turn on the lights and slow down before entering the tunnel; 2. Maintain a safe distance from the vehicle in front; 3. Do not change lanes; 4. Speeding is strictly prohibited; 5. Do not honk the horn inside the tunnel; 6. Make reasonable use of the air conditioning's internal circulation, as windows cannot be opened inside the tunnel due to the polluted air; 7. Accelerate quickly when exiting the tunnel.
