Answer: B — territory adjacent to a highway primarily improved with residences

A "residence district" is defined in relation to highways as a territory that is primarily improved with residences. This definition highlights that the area is predominantly composed of residential buildings where people live, rather than commercial or industrial spaces. The significance of this classification is relevant for various traffic regulations and speed limits, as they may differ in residential districts compared to areas designated for commercial or industrial use. This ensures that the specific needs of residential areas, such as safety and noise reduction, are taken into account when implementing traffic laws and designing roadways. Understanding this definition is crucial for law enforcement and traffic management, as it can impact decision-making regarding traffic enforcement and urban planning.
