Arizona License Plate Display Requirements
Arizona law establishes clear rules for how license plates must be displayed on vehicles registered in the state. These requirements ensure that license plates remain visible, properly illuminated, and securely mounted so that vehicles can be easily identified by law enforcement and other road users.
The Arizona Department of Transportation (ADOT) and the Motor Vehicle Division (MVD) enforce these regulations to maintain accurate vehicle identification and support public safety. Drivers must follow these rules regardless of whether they use standard plates, specialty plates, or personalized license plates.
License plate display laws apply to passenger vehicles, motorcycles, trailers, and commercial vehicles, although specific requirements may vary depending on the type of vehicle. In general, plates must be mounted in designated positions, remain unobstructed and legible, and be illuminated at night so that the registration information can be clearly read.
Failure to follow Arizona’s license plate display rules can lead to traffic citations, fines, or other enforcement actions. Understanding these requirements helps vehicle owners maintain compliance and avoid unnecessary penalties while operating their vehicles on Arizona roads.
Do Vehicles in Arizona Need One or Two License Plates?
Arizona license plate laws specify whether a vehicle must display one plate or two plates, depending on the type of vehicle. These requirements help ensure that vehicles can be identified clearly from both the front and the rear when necessary.
Most standard passenger vehicles registered in Arizona are required to display both a front and a rear license plate. The front plate must be mounted on the front of the vehicle, typically on the bumper or grille area, while the rear plate must be mounted on the back of the vehicle.
However, some vehicle types are only required to display a single rear plate. These include motorcycles, trailers, and certain specialized vehicles.

What Are Arizona’s License Plate Visibility Requirements?
Arizona law requires license plates to remain clearly visible and fully readable at all times. This rule ensures that law enforcement officers and other road users can easily identify a vehicle by its registration number.
A license plate must not be blocked, covered, or obscured by any object that prevents the characters or state name from being read. All letters, numbers, and identifying marks on the plate must remain visible from a reasonable distance.
Common Causes of Plate Obstruction
Tow hitches or towing equipment positioned directly in front of the plate
Bike racks, cargo carriers, or other rear-mounted accessories
Dirt, dust, or mud buildup covering the plate surface
Tinted license plate covers that reduce visibility
Decorative frames that block numbers, letters, or the state name

Arizona drivers should regularly inspect their license plates to ensure that no equipment or debris obstructs the view of the plate.
Keeping Plates Clean and Readable
Arizona’s climate can create conditions that affect license plate visibility. Dust, road debris, and weather exposure may gradually reduce plate readability if plates are not cleaned periodically.

Drivers should clean their plates regularly and check that vehicle accessories or modifications do not interfere with plate visibility. Decorative plate frames are generally permitted, but they must not cover any portion of the plate text or create glare that prevents the plate from being read.
How Must License Plates Be Mounted on Vehicles in Arizona?
Arizona law requires license plates to be securely mounted in designated locations on the vehicle. Proper mounting ensures that plates remain stable, visible, and readable while the vehicle is in motion.
License plates must be attached using the manufacturer’s mounting areas, typically located on the vehicle’s front and rear bumpers or designated plate brackets. Plates should be fastened with bolts or screws that hold the plate firmly in place.
Required Mounting Position
The license plate must be positioned so that it remains clearly visible and properly aligned with the vehicle. Arizona regulations require the bottom edge of the plate to be at least 12 inches above the ground when mounted.

Rear plates are generally installed on the rear bumper, tailgate, or hatch area, depending on the vehicle design. If a front plate is required, it must be mounted on the front bumper or grille area where it can be easily seen.
Secure Attachment Requirements
License plates must be mounted in a way that prevents movement, swinging, or detachment while driving.

The plate light must produce white illumination and must activate automatically whenever the vehicle’s headlights or tail lights are turned on.
