Which of the following is NOT one of the four types of traffic controls?

Traffic controls are essential for managing vehicle and pedestrian movement safely and efficiently. The four primary types of traffic controls include traffic lights, pavement markings, and road signs, each serving a specific purpose in guiding and regulating traffic.

Traffic lights are crucial for controlling intersections and ensuring orderly movement, particularly at busy junctions. Pavement markings, such as lane lines and crosswalks, provide visual guidance to drivers and pedestrians, indicating where to stop, how to navigate, and where to yield. Road signs convey important information about traffic laws, hazards, directions, and other essential notifications that help inform drivers of safe practices and the environment around them.

Traffic cones, while useful for directing traffic in temporary situations, such as construction zones or accidents, do not form part of the permanent traffic control systems recognized as the four main types. Therefore, they are not classified under the primary categories of traffic controls, which distinguishes them from the other choices provided. This understanding reinforces the importance of recognizing the established framework of traffic control devices to navigate roadways safely.
