Which sign indicates a change in driving conditions due to a divided road?

The DIVIDED HIGHWAY sign is specifically designed to inform drivers that they are approaching a section of road that has been divided, indicating that the roadway has physically separated lanes for traffic moving in opposite directions. This is crucial information for drivers, as it alerts them to the change in traffic pattern and helps them adjust their driving behavior accordingly. Understanding this sign can enhance safety by ensuring that drivers are aware that they may need to prepare for different merging conditions, lane changes, or potential hazards that may come with navigating a divided highway.

The other signs serve different purposes and do not pertain directly to the conditions of a divided road, thereby emphasizing the importance of interpreting roadway signs correctly for safe travel.
