You need to stop briefly at the curb to unload a box of merchandise for a store. Which of these signs still allows that stop?

Why

New York splits what people call parking into three categories, and each sign removes a different amount. A NO PARKING sign still lets you make a temporary stop to load or unload merchandise or passengers, so unloading the box is allowed there. A NO STANDING sign is stricter: you may stop only briefly to pick up or drop off passengers, and the driver may not get out of the vehicle, so merchandise is out. A NO STOPPING sign is the strictest: you may stop only to obey a sign, signal or officer, or to avoid a conflict with other vehicles. Read the three signs as a ladder, where NO PARKING still lets you handle goods and passengers, NO STANDING leaves only passengers, and NO STOPPING leaves nothing but what a sign, a signal, an officer or the traffic forces on you.
