What lights should be turned on before entering a highway tunnel?

[LaGraham]

Before entering a highway tunnel, motor vehicles should turn on the headlights, width marker lights, and taillights. This serves as a reminder to the vehicle ahead to avoid accidents and provides close-range illumination. Precautions for driving in tunnels are as follows: Slow down and turn on lights before entering the tunnel: If driving during the day, the light will suddenly dim upon entering the tunnel, and the human eye may take a short time to adjust. Therefore, it is advisable to reduce speed appropriately, increase the following distance, and turn on the vehicle lights to enter the tunnel safely at a relatively slower speed. Do not use high beams: Using high beams for an extended period at night can affect oncoming traffic and the vehicle ahead, as high beams can temporarily blind the driver's vision. Speeding is strictly prohibited: Tunnels usually have strict speed limits, which are clearly marked at prominent locations before entering the tunnel. Some tunnels also have speed limit reminders inside. Penalties for not turning on lights before entering a highway tunnel: A warning or fine may be issued. Traffic management departments of public security organs and their traffic police should promptly correct road safety violations. They should also impose penalties for road traffic safety violations based on facts and relevant legal provisions.
