Based on their shape, which traffic lights regulate the passage of vehicles?

Question

DentroTest · Accepted Answer

The correct answer is the circular traffic light for vehicles. Traffic lights designed to regulate motor vehicle traffic (not exclusively for specific lanes) are always circular in shape. It is essential to differentiate the shapes:   Circular: Regulate right-of-way at intersections and road sections.   Square (Lane control signals): Do not regulate right-of-way or priority (they do not strictly mandate stopping like a circular red light would for the whole road); instead, they indicate whether the specific lane they are over is open or closed to traffic.   With pedestrian silhouette: Exclusively regulate pedestrian crossings.
