What does a "No Parking" sign indicate?

A "No Parking" sign clearly indicates that it is illegal to park in that area at any time. This restriction is put in place to ensure safety, maintain traffic flow, and prevent obstruction in areas where parking could cause hazards or interruptions. Complying with a "No Parking" sign is essential for drivers to avoid fines or penalties and to promote a safe driving environment for all road users. The other options suggest varying degrees of parking permission, which do not align with the strict prohibition represented by a "No Parking" sign.
