Digital plate displays do not display registration expiration. When the registration is expired, an 'invalid' banner will be displayed under the plate characters. ADOT has collaborated with law enforcement on the way digital plates are displayed, and law enforcement is aware that registration expiration dates are not displayed digitally. Refer to your registration for expiration date information.
