What does a no-parking sign with an arrow indicate?

A no-parking sign with an arrow signifies that parking is prohibited in the direction the arrow points. This type of signage is typically used to manage traffic flow and ensure that critical areas, such as fire lanes, crosswalks, or bus stops, remain clear. By indicating a specific direction, drivers understand where they must not park, thus preventing obstructions and maintaining safety on the road. It's important for drivers to adhere to these signs to avoid potential fines and ensure that they are following local parking regulations.

Regarding the other options, one could misunderstand the sign's implication. The second choice pertains to time restrictions, which would require a different type of sign explicitly stating allowed hours. The third option is about parking regulations on the opposite side of the street, which is not relevant to the directional indication of the no-parking sign. Lastly, the fourth option implies a no-stopping rule, which is a different regulation altogether from no parking. Each of these choices reflects distinct traffic control measures that do not apply to the no-parking sign with an arrow.
