What is the function of traffic signals according to the CR-3 Traffic Code?

Traffic signals are designed primarily to control the flow of traffic at road intersections and crosswalks. They provide standardized signals that inform drivers and pedestrians when to stop, go, or proceed with caution, thereby enhancing safety and efficiency on the roads. By regulating the timing and sequence of light changes, traffic signals help manage vehicle and pedestrian movement, reduce the likelihood of collisions, and ensure a smoother flow of traffic. This function is essential in maintaining order on busy roadways where multiple vehicles and pedestrians converge.

The other choices refer to functions that are not the primary purpose of traffic signals. For instance, while they may indirectly influence pedestrian rights and behavior, the main goal isn’t to regulate those rights specifically. Informing vehicle manufacturers is unrelated to the operational purpose of traffic signals, and monitoring vehicle speeds typically falls under the domain of law enforcement and traffic cameras rather than the signaling systems themselves.
