What is a curb?

A curb is defined as a stone or concrete edging that is used to form the edge of a street or a sidewalk. It serves several important functions in urban and suburban environments, including providing a physical boundary between the roadway and pedestrian areas, helping to manage water drainage, and keeping vehicles from veering off the road. Understanding the role of a curb is essential for safe navigation on roadways, especially for mopeds and other small vehicles that might be more susceptible to losing control near the edges of the road.

Traffic signs serve to communicate rules and information to road users, but they are separate from the physical structure of a curb. Riding techniques are skills related to control and maneuvering while operating a vehicle, which do not pertain to what a curb is. Lane markings are painted lines on the road that indicate where traffic lanes are located but are also distinct from the concept of a curb. Thus, recognizing the definition and the function of a curb is crucial for safe driving and overall roadway awareness.
