Which statement best describes controlled vs uncontrolled intersections?

• A. Controlled intersections rely on signs or signals; uncontrolled rely on right-of-way rules.
• B. Controlled intersections always require stopping.
• C. Uncontrolled intersections have dedicated turn lanes.
• D. Uncontrolled intersections never involve pedestrians.

Answer: (A)

The key idea is how traffic is controlled at intersections. A controlled intersection is one that has a traffic control device—such as a stop sign, yield sign, or traffic light—that tells you when to stop or proceed. An uncontrolled intersection has no device directing traffic, so drivers must apply the standard right-of-way rules themselves. In practice, at a controlled intersection you follow the device: stop where required, yield where required, or proceed on a green signal. At an uncontrolled intersection you must judge which vehicle has the right of way, often giving priority to the vehicle on your right and yielding to pedestrians. The statement that best describes this distinction is that controlled intersections rely on signs or signals, while uncontrolled intersections rely on right-of-way rules. The other options aren’t accurate: some controlled intersections don’t require stopping (green lights or properly yielding) and not all uncontrolled intersections have turn lanes or exclude pedestrians.
