What is considered one type of traffic control?

Traffic signs are a fundamental type of traffic control used to manage the flow of vehicles and ensure safe driving conditions. They provide essential information to drivers, including speed limits, directions, warnings about upcoming hazards, and regulations they must follow. The clarity and visibility of traffic signs contribute significantly to road safety by helping to guide motorists, inform them about regulations, and enhance their awareness of the driving environment.

While other options, such as traffic barriers, road cones, and speed bumps also play roles in traffic control, they serve specific functions. Traffic barriers typically prevent vehicles from entering dangerous areas, road cones are often used temporarily to redirect traffic around obstructions, and speed bumps are designed to slow down vehicles in specific areas. However, traffic signs encompass a wide range of information and instructions essential for everyday driving, making them a primary and integral component of traffic control systems.
