What does the posted No Parking sign indicate?

Answer: B — Parking is prohibited in that area; observe posted times if any.

A No Parking sign tells you that you cannot leave your vehicle parked in that spot. If the sign lists specific hours, those are the times when parking is not allowed; outside those hours, parking may be permitted. If no times are shown, parking is prohibited at all times. This helps keep curb space clear where it’s most needed, like near intersections or crosswalks, while still allowing parking during off-hours if a time window is posted.
