Final answer:
A "Narrow Bridge" sign indicates that the bridge ahead is narrower than the approaching road. Drivers should slow down, be cautious, and sometimes yield to oncoming traffic. Respect for load limits on bridges is also essential for safety and infrastructure protection.
Step-by-step explanation:
A "Narrow Bridge" sign typically features an image of a bridge with narrowing sides or a warning text indicating that the bridge ahead is not as wide as the current road. When a driver sees a "Narrow Bridge" sign, they should prepare to slow down and proceed with caution, especially if the bridge is not wide enough to accommodate two lanes of traffic comfortably. This might mean allowing oncoming traffic to pass before crossing the bridge or being prepared to yield to oncoming vehicles. Drivers should also be mindful of the load limits on a bridge, as indicated by signs specifying weight restrictions, which help protect the structural integrity of the bridge. Understanding and reacting properly to this and other common hazard signs is crucial for road safety, as indicated in the provided information on load limit signs and the importance of knowing what these signs mean.
