What does a "no parking" sign indicate?

A "no parking" sign clearly indicates that parking is prohibited in that area at all times unless specified otherwise. This means that vehicles should not be left unattended or parked in that location. Such signage is typically placed in areas where parking could pose a safety hazard, obstruct traffic flow, block driveways, or hinder emergency services. Understanding this sign is crucial for drivers to avoid fines and ensure the smooth operation of roadways.

The other options present various scenarios under which parking might be allowed, but these do not apply when a "no parking" sign is present, reinforcing the importance of recognizing and adhering to such regulations.
