All states have traffic laws that require motor vehicles on public highways, streets, roads, and driveways to have a rear license plate or tag—and most states also require a license plate on the front of a motor vehicle.

States usually require the license plates or vehicle registration to be renewed periodically—often annually and in connection with payment of a motor vehicle tax or inspection of the vehicle for safety and compliance with emissions standards.

In some states tickets or citations for no front or rear license plate or for expired plates/tags on your vehicle are known as fix-it tickets and the ticket or citation will indicate that it is a correctable violation of traffic laws. If you fix the missing-or-expired license plate problem within the required period and get the signature of an authorized person (a local police officer) the court may dismiss the ticket.

But if you fail to fix the missing-or-expired-tags problem within the required period you must pay the fine for the violation and you may be issued another ticket that will be part of your driving record. And if you fail to pay the ticket or appear in court on the hearing date the court may issue a warrant for your arrest.

In Arizona, motor vehicles are required to have a rear license plate, and Arizona is one of the states that does not require a front license plate on most vehicles. License plates and vehicle registrations must be renewed periodically, with the frequency depending on the type of registration. Renewal often involves payment of a vehicle tax and may require a vehicle inspection for safety and emissions compliance. If a vehicle is found without a required rear license plate or with expired tags, the driver may receive a citation. In Arizona, such citations can be considered 'correctable violations' or 'fix-it tickets.' This means that if the driver remedies the issue by a specified deadline and obtains verification from an authorized person, such as a police officer, the court may dismiss the citation. However, failure to correct the issue within the required timeframe or to pay the fine can result in additional penalties, including the possibility of another citation that affects the driver's record. Noncompliance with court directives, such as failing to pay a fine or appear in court, can lead to more severe consequences, including the issuance of an arrest warrant.
