What is defined as the part of a trafficway typically and ordinarily used for motor vehicle travel?

The part of a trafficway that is typically and ordinarily used for motor vehicle travel is known as the roadway. This term specifically refers to the portion of a street or highway that is designed and intended for vehicles to drive on, as opposed to areas designated for other uses, such as sidewalks for pedestrians or shoulders for parking or emergency situations. Understanding the definition of a roadway is essential for grasping traffic regulations, as different types of roadways may have varying rules and expectations for driver behavior. The other terms, while related to traffic areas, serve different purposes; for instance, sidewalks are meant for pedestrians, shoulders are typically used for emergency vehicles or breakdowns, and driveways provide access to private properties.
