What lights should be used when passing through an arched bridge or slope?

When passing through an arched bridge or slope, use the high and low beams alternately. Below are the regulations regarding the use of vehicle lights: 1. Turn signals: When turning left, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn, the left turn signal should be activated in advance; when turning right, changing lanes to the right, returning to the original lane after overtaking, or parking by the roadside, the right turn signal should be activated in advance. 2. Special circumstances: When a vehicle passes through sharp curves, slopes, arched bridges, crosswalks, or intersections without traffic light control at night, it should alternately use high and low beams to signal. When approaching sections with limited visibility such as sharp curves or the top of a slope, or when overtaking or encountering an emergency, the vehicle should slow down and sound the horn as a warning.
When driving over an arched bridge slope, I believe the safest approach is to turn on the low beam headlights. Arched bridges often have curved ramps, where the upward tilt of the lights during ascent may affect oncoming visibility, and direct lighting during descent can easily cause glare. Low beams ensure clear visibility of the road while minimizing interference with other drivers, reducing the risk of accidents. Especially at night or on cloudy days when lighting conditions can fluctuate, using low beams is the most reliable option. In heavy rain or fog, it's advisable to additionally turn on fog lights for enhanced illumination, but high beams should be used sparingly as slope reflections can worsen visibility. Ultimately, this method is rooted in the core principle of driving safety—adapting to changing road conditions to protect both yourself and others. Making it a habit can greatly simplify your driving experience.
