A plan view of two accessible parking spaces with a 60-inch wide access aisle between them and with notes explaining key features for cars:

Sign with the international symbol of accessibility mounted high enough so it can be seen while a
vehicle is parked in the space

If the accessible route is located in front of the space, install wheelstops or other barriers to keep vehicles from reducing width below 36 inches

Access aisle of at least 60-inch width must be level (1:50 maximum slope in all directions), be the same length as the adjacent parking space(s) it serves and must connect to an accessible route to the building. Ramps must not extend into the access aisle

Boundary of the access aisle must be marked. The end may be a squared or curved shape

Two parking spaces may share an access aisle
