# Explanation: Movable Bridge Sign
This warning sign warns about the **proximity of a movable bridge**, that is, a bridge that can be raised or moved to allow boats to pass. Drivers must be prepared to stop and wait, as traffic may be interrupted when the bridge opens. This sign is common in port areas and near navigable canals.
