What does the sign that tells you to watch for cross traffic look like?

The sign that indicates you should watch for cross traffic is represented by a black cross on a yellow diamond. This specific design is used for warning signs in traffic regulations, as the yellow color signals caution. The black cross symbolizes the potential for intersecting traffic, prompting drivers to slow down and be alert for vehicles that may be crossing their path. This design effectively communicates the importance of vigilance in areas where cross traffic might unexpectedly appear, enhancing safety for both drivers and pedestrians.

The other options do not align with standard traffic sign conventions for warning signs. Red signs typically indicate stop or yield commands, blue signs usually provide service or informational messages, and green signs offer directional guidance.
