Which sign warns drivers of an approaching side road at an intersection?

1. School zone

2. Side road

3. Railroad sign

4. Bicycle zone

The correct answer is: Side road

The sign that warns drivers of an approaching side road at an intersection is specifically designed to alert drivers to the presence of other roads that may intersect with the main roadway. This type of sign typically features a distinctive shape and symbol that indicates the potential for vehicles to enter or exit from the side road, promoting caution for drivers as they approach. By highlighting the possibility of cross traffic and the need to watch for vehicles merging in from the side, this sign helps enhance safety at intersections where visibility may be limited or where drivers may not expect to encounter additional roadways. Other signs, such as those indicating school zones, railroad crossings, or bicycle areas, serve different purposes. A school zone sign focuses on the need to slow down and be alert for children near schools, a railroad sign warns of nearby train tracks, and a bicycle zone sign indicates areas where cyclists may be present. Each of these is intended to inform drivers of specific hazards or considerations, rather than the presence of a side road.
