What is an Alley primarily used for?

Answer: B — Access to rear entrances of buildings or lots

The primary purpose of an alley is to provide access to rear entrances of buildings or lots. This design allows for the loading and unloading of goods and services, access for maintenance professionals, and facilitates parking without disrupting the flow of more significant thoroughfares. Alleys are typically narrower than standard streets and are not intended for through traffic; instead, they serve a functional role in urban planning by enabling property owners to access their premises without having to navigate through front-facing roads. This enhances the overall efficiency of traffic management in urban areas, as it helps to keep main roads clearer and less congested.
