What defines a "no parking" zone?

A "no parking" zone is specifically defined as an area where parking is prohibited. This means that vehicles are not allowed to be parked in these designated areas at any time, contributing to safety and ensuring that roads and pathways remain clear for traffic flow. Such zones are typically marked with signage indicating that parking is not permitted, thus helping to prevent obstructions that could lead to accidents or impede emergency services.

The other options suggest various forms of parking regulations that either allow for limited parking or designate areas for specific purposes, such as loading and unloading, or creating exceptions based on the time of day. However, a true "no parking" zone specifically emphasizes that no vehicle can be parked there at any time, reinforcing the strict nature of this regulation.
