What is the rule regarding parking in an alley?

The rule stating that it is prohibited to stand or park in an alley is important for maintaining clear access for emergency vehicles, as well as for other vehicles that may need to navigate these narrower spaces. Alleys are typically meant for utility access, deliveries, and other essential services rather than for general parking. By prohibiting parking in these areas, it helps ensure that they remain unobstructed, thus enhancing traffic flow and safety.

Other options suggest exceptions or conditions under which parking might be permitted in an alley, but they do not align with the fundamental purpose of keeping alleys clear for their intended use. Therefore, understanding the regulation in the context of public safety and efficient traffic management reinforces why parking is generally prohibited in such spaces.
