Illinois License Plate Laws

Illinois requires most passenger vehicles to display both a front and rear license plate. The state’s license plate laws are established under the Illinois Vehicle Code (625 ILCS 5) and include requirements for plate placement, visibility, registration stickers, plate illumination, and prohibited accessories such as obstructive covers or frames.

Front License Plate Requirements

Illinois is one of the states that requires two license plates on most passenger vehicles. Both plates must remain securely attached and clearly visible whenever the vehicle is operated on public roads.

Does Illinois require a front license plate?

Yes. Under 625 ILCS 5/3-413, Illinois requires both a front and rear license plate for standard passenger vehicles.

The front plate must be securely mounted to the exterior front of the vehicle. Placing the plate on the dashboard, inside the windshield, or in any other location that is not permanently mounted does not satisfy state law. Operating a vehicle without a required front plate may result in a traffic citation.

Where must license plates be mounted?

Illinois requires license plates to be securely fastened in a horizontal, upright position where they are clearly visible and easy to read.

Both plates must remain firmly attached to the vehicle and may not swing, tilt, or hang in a manner that obstructs visibility. The rear plate must be mounted on the rear exterior of the vehicle, while the front plate must be displayed on the front bumper or another approved factory mounting location.

License Plate Covers and Frames

While Illinois allows drivers to use certain license plate accessories, they cannot interfere with the readability of the plate. Any cover or frame that obscures identifying information may violate state law.

Are tinted license plate covers legal in Illinois?

No. Tinted, smoked, opaque, or reflective license plate covers are not legal if they reduce the visibility or readability of the plate.

Even clear plastic covers may violate Illinois law if they create glare, reduce reflectivity, or make the plate difficult to read under daylight or nighttime conditions. These restrictions apply to both front and rear license plates.

Are license plate frames legal?

Yes. License plate frames are permitted as long as they do not cover any required information printed on the plate.

Frames must not obscure the state name, any letters or numbers, or the annual registration sticker displayed on the rear license plate. Before installing a decorative frame, drivers should ensure that the entire plate remains fully visible.

License Plate Display Rules

Properly displaying your license plates is just as important as having valid registration. Illinois law requires plates to remain visible, legible, and free from any obstruction that could interfere with identification.

What counts as a license plate obstruction?

A license plate is considered obstructed if any object, material, or condition prevents officers or automated systems from clearly reading the information displayed on the plate.

Examples include tinted or reflective covers, frames that hide letters, numbers, the state name, or the registration sticker, excessive dirt or mud, anti-camera sprays, and damaged or bent plates. Drivers are responsible for keeping both license plates clean and readable at all times.

Can you alter or modify an Illinois license plate?

No. Illinois law prohibits altering, painting, bending, drilling through identifying information, or otherwise modifying an official license plate.

If a plate becomes damaged, faded, or unreadable, it should be replaced through the Illinois Secretary of State before continuing to operate the vehicle.

Rear License Plate Light Requirements

Illinois requires the rear license plate to remain visible after dark. Proper illumination is considered required vehicle equipment and helps law enforcement identify vehicles during nighttime operation.

Does Illinois require a rear license plate light?

Yes. The rear license plate must be illuminated by a white light whenever the vehicle’s headlights are in use.

The light must make the plate clearly readable from a distance of at least 50 feet. A burned-out or malfunctioning license plate light may result in an equipment citation or fix-it ticket.

Registration Sticker Rules

Illinois continues to use annual registration stickers to indicate the validity of a vehicle’s registration. Drivers should regularly inspect the sticker to ensure it is current and properly displayed.

What are Illinois’ license plate sticker requirements?

Illinois issues an annual registration sticker that must be attached to the rear license plate.

The sticker displays the vehicle’s registration expiration date, which typically expires on June 30 of the registration year. Driving with an expired, missing, or improperly displayed sticker may result in a traffic citation.

Common License Plate Violations

Most Illinois license plate citations result from improper display, missing registration stickers, or obstructed plates. Regularly inspecting your plates and ensuring they remain visible can help prevent unnecessary traffic stops.

Common violations include operating a vehicle without a required front plate, displaying an obstructed license plate, using an illegal cover or frame, driving with an expired registration sticker, or failing to maintain a working rear license plate light.

Illinois License Plate Violation Fines

Illinois treats license plate violations as traffic or equipment offenses. The exact penalty depends on the specific violation and the court handling the citation.

What is the fine for a license plate violation?

A missing front license plate may result in fines that typically range from $50 to $500, depending on the circumstances and local court. Other violations, including obstructed plates or expired registration stickers, carry penalties determined by the court.
