What are the two main types of intersections?

The correct answer identifies the two primary categories of intersections based on their configuration and functionality. Three-way intersections feature three roads converging at a single point, commonly seen at T-junctions. Four-way intersections involve four roads meeting at a central point, which is typical in city blocks.

Understanding these types of intersections is critical for drivers, as they dictate different traffic flow patterns, signaling, and rules for right-of-way. Each category has distinct operational dynamics that affect how vehicles navigate through them, such as differing visibility, potential blind spots, and the strategies required for safe maneuvering.

On the other hand, while controlled and uncontrolled intersections refer to the presence or absence of signals or signs guiding traffic, they do not categorize the physical configuration of the intersection itself. Similarly, roundabouts and interchanges represent specific designs of roadways but are not comprehensive as basic types of intersections.
