What is the main purpose of traffic signals as stated in the CR-3 Traffic Code?

The main purpose of traffic signals, as stated in the CR-3 Traffic Code, is to control and direct vehicular and pedestrian traffic safely. Traffic signals are crucial for managing how vehicles and pedestrians interact at intersections and crosswalks, ensuring that both can proceed in an organized manner to prevent accidents and enhance safety on the roads. By clearly conveying when to stop and when to go, traffic signals help to establish right-of-way, thereby facilitating smooth traffic flow and reducing conflicts between different road users.

The other options, while they may pertain to different aspects of roadway management or design, do not align with the primary function of traffic signals. For instance, providing information about weather conditions would pertain more to road signs or electronic message boards. Indicating speed limits is a distinct function of speed limit signs rather than traffic signals. Serving as decorative road features is not an intended purpose, as traffic signals are primarily functional devices aimed at ensuring safety and efficiency in traffic management.
