Loading-unloading zones are specific areas designated for the loading and unloading of packages, materials, shipments, and, at times, passengers. Parking in these areas is usually prohibited or restricted to a short period of time, and these zones are mostly used by commercial vehicles.
No parking loading zone signs are covered in the R7 series of MUTCD signs, R7-6 specifically where “R7-6 is shown as a vertical rectangular white sign with a red border and the words "NO PARKING" in large red letters on the top two lines above the words "LOADING ZONE" in red on the next two lines. A two-direction horizontal red arrow is shown on the fifth line.”
FHWA-MUTCD further details about the sign design for different situations, the information that these signs should convey, and how these should be placed.
Loading and unloading zones are created to enable drivers to pick up or drop off packages or persons with minimum delay or waiting time. Congestion in loading areas can defeat the very purpose these are created for. However, a carefully and strategically designed loading zone with dedicated traffic inflow and outflow lanes can solve half the problem. Additionally, implementing controls such as parking and turn restrictions can also help in preventing vehicles from queuing up.
No parking loading and unloading zone signs work well to mark loading areas, communicate the policy specific to that area such as time limits and penalties, and keep congestion at bay. It may also help to appoint well-trained personnel who can communicate with people and ensure a smooth flow of traffic.
Loading-unloading zones are usually created by businesses and merchants as a means to facilitate quick and convenient pick-ups and drop-offs. These can be created by approaching the local city council with a completed application. The council may approve or reject the application based on considerations such as the location and length of the zone, hours of operation, parking demand, volume of goods to be handled in the zone, and other benefits and possible disadvantages associated with the zone desired.
Any vehicles that violate the clearly stated policies of a loading zone run the risk of being towed away, often at the owner’s expense. In most cases, loading zone signage conveys the standing time limit as well as the possible consequence of a violation.
