What does a 'No Parking' sign indicate?

Answer: C — You cannot park there at any time

A 'No Parking' sign clearly indicates that parking is prohibited at all times in that specific area. This means that drivers must refrain from leaving their vehicles unattended there, ensuring that the space is kept clear for other road users, emergency vehicles, or to maintain traffic flow. This rule is important for safety and efficient use of public roadways. Other options suggest varying conditions under which parking might be permissible, such as limited time or specific times like night or weekends. However, the presence of a 'No Parking' sign unequivocally removes all such allowances, reinforcing the strict prohibition it imposes. Understanding this signage is essential for adhering to traffic regulations and avoiding penalties.
