Limited access locations are all non-residential locations that do not fit in the standard business description. This means that churches, hospitals, farms, and various other location types fall under the limited access category.
Locations can be deemed limited access for various reasons, whether it be for the inaccessibility to the public during standard business hours; remoteness; increased pedestrian traffic in the area, etc.
For instance: airports, military bases, and police stations are limited access due to the fact that they have heightened security and are generally not accessible to the general public during standard business hours. Not everyone with a truck can come to an airport or military base and request to pick something up or drop something off there.
Churches, hospitals, parks, and locations akin to those are considered limited access due to increased pedestrian traffic and lowered maneuverability.
