“Disabled veteran”, as used in this section, means (1) any veteran, as defined in section 27-103, who performed service in time of war, as defined in section 27-103, and (2) (A) one or both of whose legs or arms or parts thereof have been amputated or the use of which has been lost, (B) who is blind, paraplegic or hemiplegic, or (C) who has traumatic brain injury, any such disability described in subdivision (2) of this section being certified as service-connected by the United States Department of Veterans Affairs.

The card shall identify the disabled veteran and the motor vehicle and shall state that such disabled veteran is qualified to receive the card, that the card, plate or plates shall be returned to the commissioner if the registration of the motor vehicle is cancelled or transferred and that the card is for the exclusive use of the disabled veteran to whom it is issued, is not transferable and will be revoked if presented by any other person or if any privilege granted under this section is abused. If not so revoked, the card shall be renewable every four years at the time of registration of motor vehicles. No penalty shall be imposed for the overtime parking of any motor vehicle bearing a number plate issued under this section when it has been so parked by the disabled veteran to whom the plate and an identification card were issued or by any person operating such vehicle when accompanied by such disabled veteran, provided the length of time for which such vehicle may remain parked at any one location shall not exceed twenty-four hours. The surviving spouse of a disabled veteran issued such special registration may retain any such registration and number plates without charge for his or her lifetime or until such time as he or she remarries.
