When a motor vehicle passes through a railway crossing, sharp curve, narrow road, or narrow bridge, the maximum driving speed shall not exceed 30 km/h. When a motor vehicle encounters any of the following situations, the maximum driving speed shall not exceed 30 kilometers per hour, and for tractors, battery-powered vehicles, and wheeled special-purpose machinery vehicles, the speed shall not exceed 15 kilometers per hour: 1. When entering or exiting a non-motorized lane, passing through a railway crossing, sharp curve, narrow road, or narrow bridge; 2. When making a U-turn, turning, or descending a steep slope; 3. When encountering fog, rain, snow, dust, or hail with visibility within 50 meters; 4. When driving on icy, snowy, or muddy roads; 5. When towing a malfunctioning motor vehicle.

I've studied traffic regulations, and the speed of vehicles when passing through narrow bridges must absolutely not exceed 30 kilometers per hour. This limit is mandatory because the limited space on narrow bridges makes collisions more likely at higher speeds. For example, when I drive across narrow bridges in rural areas, I always reduce my speed to around 25 in advance to avoid being unable to dodge oncoming vehicles when passing each other. Once, I forgot to slow down while crossing a bridge on a rainy day, and my car skidded, nearly plunging into the river—a real wake-up call. Safe driving requires us to maintain this speed limit, especially when the bridge is aging or the weather is bad, when it should be reduced to below 20 to protect both ourselves and the bridge structure. Remember, frequently checking the rearview mirror and brake condition can enhance safety when passing through.

I've got some real insights about driving across narrow bridges: you must keep your speed below 30 km/h! When I was younger, I did something foolish - accelerated hard trying to rush across the bridgehead, only to scrape against the guardrail leaving deep scratches and even denting the bumper. Now that I'm more experienced, whenever I see a narrow bridge sign, I ease off the throttle and slow down below 30 km/h for a smooth, worry-free crossing. Narrow bridges often have many curves with poor visibility - speeding increases braking distance with serious consequences. On weekend trips when I take mountain roads, driving slowly across narrow bridges actually lets me enjoy the scenery and have pleasant conversations with family. Maintaining this habit not only follows traffic rules but also extends the vehicle's lifespan.

A speed of 30 km/h is the absolute limit when crossing a narrow bridge—never exceed it! The confined space poses significant risks, and higher speeds can easily lead to loss of control, resulting in fatal collisions with oncoming vehicles or bridge piers. I've reviewed accident reports, which show that speeding accounts for up to 70% of such incidents, often leaving victims severely injured or comatose. That's why I constantly remind myself while driving: keep the speedometer below 30, and reduce it further to under 20 during rain or snow. This speed limit provides ample reaction time to anticipate potential hazards like pedestrians or obstacles. Adhering to this rule is a lifesaving necessity—no room for carelessness.

I always comply with traffic regulations: maintaining speeds below 30 km/h when crossing narrow bridges. The law clearly sets this limit - exceeding it incurs a 200 yuan fine plus 3 penalty points, which simply isn't worth the risk. Narrow bridges have fragile structures, and speeding vibrations can damage the bridge deck, increasing maintenance costs. During long drives, I pay special attention, observing road signs in advance to reduce speed below 30 km/h, ensuring no speed camera violations. Narrow bridges on urban expressways are prone to congestion - driving slowly prevents scratches and maintains order. Developing this habit significantly enhances safety - never gamble with speed just to save time.
