What should you do when coming up to a one-lane bridge?

Answer: B — Slow down and proceed only if clear

When approaching a one-lane bridge, it is essential to prioritize safety and ensure that the path is clear before proceeding. Slowing down allows you to assess the situation effectively, as visibility may be limited and other road users may also be maneuvering in that area. By checking for oncoming traffic, you can determine whether it is safe to cross or if you need to yield. This cautious approach helps prevent potential collisions and ensures smoother navigation for all vehicles involved. Other options, such as accelerating quickly or honking to alert traffic, may introduce unnecessary risks and could lead to dangerous situations. Stopping without a signal could also create confusion or cause delays for other drivers. Prioritizing clarity and communication at one-lane bridges is crucial for safe transit.
