(B) After July 1, 2008, as new signs designating disabled parking are erected, the signs shall indicate the penalties imposed by this section. Nothing in this section shall be construed to require the removal or alteration of any existing sign designating disabled parking.
T.C.A. § 55-21-105 (b)
(5) Van accessible parking spaces shall have an additional sign marked “Van Accessible — Priority for Wheelchair User” mounted below the sign required by subsection (c). The van accessible parking spaces may have an additional sign marked “Priority Should Be Given to Disabled Van Access. Other Disabled Vehicles Should Use Only If No Other Available Disabled Spaces” mounted below other required signs. Van accessible parking spaces are not restricted to disabled van access; provided, that disabled vehicles other than vans should not use van accessible parking spaces when another accessible disabled parking space is available.
T.C.A. § 55-21-105
(c) Each such parking space must be marked and maintained with the stylized wheelchair symbol designated by § 55-21-104, as that section existed on June 30, 2020; provided, that such parking spaces may, at the discretion of the owner, be marked with the symbol of access designated under § 55-21-104, to the extent that such marking complies with federal law. The marking may be by a sign on a pole. Nonconforming markings or signs shall be acceptable during the useful life of the markings or signs, which may not be extended by other than normal maintenance as long as the markings or signs provide reasonable notice of the specially marked parking space.
