Controlled intersection is described as?

• A. Regulated by signs and lights
• B. Regulated by signs and speed bumps
• C. Regulated by signs and roundabouts
• D. Regulated by lane markings

Answer: (A)

A controlled intersection is described as one where traffic flow is regulated by official devices such as signs and traffic lights, which tell drivers when to stop and when to go. This setup provides clear, codified rules for who has the right of way, reducing conflicts at the intersection. Speed bumps aren’t the controlling mechanism at intersections; they slow traffic but don’t establish the stop/go rules. Roundabouts rely on yielding and circulating traffic rather than signals as the primary control, and lane markings alone guide movement without the definitive stop/go instructions that signs and lights provide.
