When approaching a sign for a "Drawbridge", what must drivers do?

When approaching a "Drawbridge" sign, drivers must slow to a stop when directed. This is important because drawbridges are designed to open for boats, and when this occurs, it is crucial for safety that vehicles do not continue to drive forward. The sign serves as a warning that the bridge may open, so drivers need to be prepared to halt, ensuring both their safety and that of any pedestrians and cyclists.

This practice promotes cautious driving behavior in areas where significant changes in traffic conditions can occur suddenly, such as the opening of a bridge. Recognizing and responding correctly to such signs is part of responsible driving, especially in environments where vehicles must share space with maritime traffic.
