How is the four-way intersection sign represented?

The correct representation of a four-way intersection sign is a plus sign. This shape is used to indicate that there are roads intersecting at the intersection, allowing drivers to anticipate the possibility of vehicles coming from multiple directions. The plus sign format visually conveys the concept of crossing paths, which is essential for drivers to approach the intersection with caution and awareness.

The other shapes listed do not accurately convey the message of a four-way intersection. For example, a square typically represents regulatory signs, a diamond indicates warnings, and an arrow often indicates direction or movement rather than the presence of multiple intersecting roads. Understanding the meaning behind the plus sign can help drivers navigate intersections safely.
