What is the difference between a narrow road and a narrow bridge?

Narrow road signs are divided into narrowing on both sides, narrowing on the right, and narrowing on the left; narrow bridge signs refer to structures built where the road width is less than the normal road width. Narrow road signs: The 'narrowing on both sides' sign is used to alert drivers to the narrowing of the road ahead, requiring them to slow down and yield to oncoming traffic. The 'narrowing on both sides' primarily refers to roads that symmetrically narrow along the centerline, with this sign placed at the starting point of roads where the width is reduced to less than 6 meters. Narrow bridge signs: The narrow bridge sign is placed at an appropriate location before a bridge where the road width is less than the normal road width, and the bridge width is less than 6 meters. When crossing a narrow bridge, the speed should not exceed 30 km/h. During nighttime driving, when encountering a narrow bridge traffic warning sign, drivers should switch from high beams to low beams.
After driving for so many years, I feel the biggest difference between narrow roads and narrow bridges lies in the driving pressure and strategies. Narrow roads usually refer to those rural paths or old urban alleys, where the road surface is narrow but flanked by flat ground or green belts. You can pull over anytime to let oncoming vehicles pass, with more maneuvering space and a relatively relaxed mindset. But narrow bridges are entirely different—they are structurally narrow, like old iron bridges over small rivers, barely wide enough for one vehicle, where you can't casually stop or overtake because below is either a height or water, and stopping could block the entire passage. I still remember driving on a highway over a narrow bridge, feeling the car vibrate, forcing me to slow down to under 20 mph in advance to avoid sharp turns or sudden braking. While accident rates might be higher on narrow roads, the consequences of issues on narrow bridges are far more severe, so I’ve made it a habit to use navigation apps to identify upcoming narrow bridges early and prepare accordingly.
I've only had my driver's license for a year and have driven on narrow roads and narrow bridges a few times. I feel that new drivers are more afraid of narrow bridges. On narrow roads, although the cars are squeezed together, you can at least pull over at any time to let others pass first, with a greater margin of safety. But on a narrow bridge, it's different—the width is strictly limited, and you can only go straight across. With open space or deep water on either side, it's really nerve-wracking. Like the last time I was on a small rural bridge, there was a width restriction sign at the entrance, allowing only one lane to pass. My palms were sweating, but luckily I slowed down and made it across. Later, I checked the traffic rules and found that narrow bridges usually have special speed limit signs or no-stopping signs, reminding drivers to maintain a steady speed, unlike narrow roads where you can handle things more flexibly. Now, I use my phone's navigation app, which gives voice alerts about upcoming narrow bridges. Slowing down in advance makes me feel much more at ease. I recommend new drivers try this trick as well.
