When passing under an arch bridge at night, alternately use the high and low beams at least twice. Below is a detailed introduction to the usage of lights: Nighttime driving: When turning at an intersection at night, use low beams. When driving on roads with low visibility at night, turn on high beams. When passing through sharp curves at night, alternately use high and low beams at least twice. When passing over slopes at night, alternately use high and low beams at least twice. When passing under an arch bridge at night, alternately use high and low beams at least twice. When passing through a crosswalk at night, alternately use high and low beams at least twice. When passing through an intersection without traffic lights at night, alternately use high and low beams at least twice. When overtaking at night, first turn on the left turn signal, then alternately use high and low beams at least twice, and then turn on the right turn signal. When meeting other vehicles at night, turn on low beams. Foggy weather driving: Turn on the width marker lights, front and rear fog lights, and hazard warning lights. 3. In case of a malfunction: Turn off the main headlights and turn on the width marker lights and hazard warning lights.
The first time I drove over an arched bridge at night, I felt my heart racing. It was an old stone arch bridge, and my driving instructor had emphasized during lessons that in places with canopies or limited visibility, low beams must be used. He said the low beam light is more focused, evenly illuminating the road without blinding others. Sure enough, once I switched to low beams, I could clearly see the potholes and cracks on the bridge surface and passed safely. Later, as I drove more on my own, I realized that if there was fog or rain on the bridge, using high beams would cause glare and make it impossible to see anything. Now, whenever I approach any arched bridge, I habitually switch to low beams first to check the light conditions and ensure everything is normal. Light maintenance is also crucial—replace old bulbs promptly without delay. Developing such detailed habits can prevent accidents, and using the correct lighting to see the road clearly provides much more peace of mind.
