What does a "no parking" sign indicate?

Answer: B — You must not park in that area under any circumstance

A "no parking" sign indicates that parking is prohibited in that area under any circumstance. This means that vehicles should not be left unattended in the designated zone, and doing so could result in a citation or towing. These signs are typically placed in areas where parking could obstruct traffic, create safety hazards, or disrupt the flow of pedestrians, among other reasons. In contrast, other sign meanings might suggest limited parking or specific conditions under which parking is permitted. For instance, certain signs may allow brief stops for passenger drop-off or designate times when parking is permitted, but a "no parking" sign unequivocally prohibits stopping in that location altogether.
