Which statement best describes a motorway?

The statement that best describes a motorway is one that emphasizes its intended use for certain types of motorized traffic, which is captured in the correct answer. Motorways are typically designed to facilitate high-speed vehicular traffic and are characterized by features such as multiple lanes, limited access points, and no traffic signals or frequent stops, allowing for uninterrupted travel. They are reserved for motor vehicles, meaning that traditional bicycles, pedestrians, and other forms of non-motorized transportation are prohibited.

The other descriptions do not accurately represent the characteristics of a motorway. A road with multiple traffic lanes and frequent stop signs suggests a different type of roadway that involves more traffic control measures, which is not the case for motorways. A residential street with limited vehicle access focuses on lower speed limits and local traffic, contrasting sharply with the high-speed nature of motorways. Similarly, a road that allows only bicycles and pedestrians is not what a motorway represents, as these roads are designed explicitly for motorized vehicle use, excluding non-motorized forms of transportation entirely. This distinction is crucial in understanding the function and designation of motorways in road networks.
