What term describes an intersection that uses signals to control right-of-way?

• A. Uncontrolled intersection
• B. Roundabout
• C. Controlled intersection
• D. Pedestrian crossing

Answer: (C)

The key idea is how traffic at an intersection is controlled. When signals tell you when to stop, wait, or go, the intersection is described as controlled because the right-of-way is directed by those signals. The lights coordinate movements from all directions, making it safer and clearer who goes first, especially when vehicles want to go straight, turn left, or turn right.

A roundabout operates differently: it uses a circulating path and typically yields to traffic already in the circle, with signals sometimes used only in special cases. That’s not about signal-controlled right-of-way, so it isn’t the best fit here. A pedestrian crossing describes a crosswalk area rather than how the entire intersection is controlled. An uncontrolled intersection has no signals or signs to regulate who goes first, which is the opposite of what’s described. So the term that matches “uses signals to control right-of-way” is a controlled intersection.
