How to Use Lights Before Entering a Two-Way Traffic Tunnel?
2 Answers
Methods for using lights when a motor vehicle enters a two-way traffic tunnel are as follows: 1. Turn on the low beam when there is lighting inside the tunnel. 2. Alternate between high and low beams when there is no lighting inside the tunnel. The methods for turning on the lights are as follows: 1. Turn the left light control switch forward one notch for parking lights. 2. Turn it forward two notches for low beam. 3. Push the light control lever forward once for high beam. 4. Lift the light control lever forward and upward once for the right turn signal. Precautions for using vehicle lights are as follows: 1. Turn on the low beam when driving at night. 2. Do not use high beam when a following vehicle is driving close to the vehicle in front in the same direction. 3. Alternate between high and low beams when passing sharp curves, slopes, arched bridges, crosswalks, or intersections without traffic signal control at night.
Before entering a bidirectional tunnel, I always turn on the low beams in advance to make my position visible to other drivers and avoid collisions with oncoming vehicles. The dim lighting inside the tunnel makes it essential to use headlights for better visibility—safety first. I usually slow down about 100 meters before the entrance to check if the lights are functioning properly, and I never use high beams as they can blind oncoming drivers. Bidirectional traffic means complex flow, and keeping the lights on also helps surveillance cameras capture clearer footage, reducing accident risks. Don’t rush to turn off the lights immediately after exiting the tunnel—wait until your eyes fully adjust to the external light. Regular maintenance of the headlights is crucial to ensure the bulbs aren’t burnt out. These habits give me peace of mind every time I pass through a tunnel. After all, safe driving is everyone’s responsibility—don’t cut corners to save a bit of electricity.
