The Federal Highway Administration offers two designs for the Van Accessible plaques, both used in different conditions.  The rectangular blue supplemental sign with a white border and the words "VAN ACCESSIBLE" in white on two lines (R7-8b) is required to designate parking spaces that can accommodate wheelchair vans. The rectangular white supplemental sign with a green border and the words "VAN ACCESSIBLE" in green on two lines (R7-8a) is required to direct drivers to van-accessible parking facilities.  However, local or state jurisdictions may require a particular color scheme for these signs.
