Montana vehicle license plate laws are governed by Montana Code Annotated Title 61. Montana is a two-plate state – both front and rear license plates are required on all standard passenger vehicles. Main rules cover plate mounting, cover and frame restrictions, illumination requirements, and registration sticker placement. Montana does not require an emissions inspection sticker, but registration stickers must be current.
Front Plate Requirement
Montana requires both front and rear license plates on standard passenger vehicles. This applies to all standard passenger cars, trucks, and SUVs registered in Montana.
Does Montana require a front license plate on standard passenger vehicles?
Yes. Montana requires both front and rear license plates on all standard passenger vehicles. Driving without a front plate is a traffic violation in Montana. Both plates must be securely mounted on the exterior of the vehicle – placement on the dashboard or inside the windshield does not satisfy the requirement.
Plate Covers
Tinted or opaque license plate covers are prohibited in Montana. Any material placed over either plate that reduces readability or reflectivity violates Montana law.
Are tinted or clear license plate covers legal in Montana?
No. Tinted or opaque license plate covers are illegal in Montana. Montana Code Annotated requires license plates to remain clearly legible at all times. Any cover that reduces the visibility, reflectivity, or legibility of either plate is prohibited. This includes materials marketed as clear but that impair readability under certain lighting conditions. Anti-camera sprays and reflective coatings are also prohibited.
Plate Frames
License plate frames are permitted in Montana provided they do not obstruct any required information on either plate.
Can I use a license plate frame on my Montana plates without violating state law?
License plate frames are permitted in Montana provided they do not obstruct any portion of either plate, including the state name, any characters in the plate number, or any registration stickers. Frames that cover any required information on either the front or rear plate are violations. Thin border-only frames that stay clearly within the plate edges are the safest choice.
Plate Mounting
Montana requires both front and rear plates to be securely fastened and clearly visible from the front and rear of the vehicle respectively.
Where must Montana license plates be mounted, and can I display them inside the windshield?
Montana requires both front and rear license plates to be securely fastened, horizontally mounted, and clearly visible from the front and rear of the vehicle. Plates must not swing, rattle, or be angled in a way that reduces readability. Displaying the front plate on the dashboard or inside the windshield is not a valid alternative to exterior mounting.
Plate Illumination
Montana requires the rear license plate to be illuminated by a white light when the vehicle’s headlights are in use.
Does Montana require the rear license plate to be illuminated at night?
Yes. Montana requires the rear license plate to be illuminated by a white light that makes it clearly readable from at least 50 feet when the vehicle’s headlights are in use. A non-functioning plate light is an equipment violation subject to a traffic citation. Ensure your rear plate light bulb is functioning at all times when driving after dark.
Registration Stickers
Montana issues annual registration stickers that must be properly affixed to the rear license plate. Montana does not require an emissions or safety inspection sticker.
What are Montana’s rules for registration stickers, and where does the sticker go on the plate?
Montana issues annual registration stickers that must be affixed to the rear license plate as directed by your county treasurer’s office. The sticker must be current and clearly visible. Montana does not require an emissions inspection sticker or a safety inspection sticker. Driving with an expired or missing registration sticker is a traffic violation.
Plate Obstruction
Montana prohibits any cover, device, or material that makes either plate difficult to read or that reduces the plate’s reflectivity. The following items are specifically prohibited.
What types of covers or objects count as illegal license plate obstruction in Montana?
Montana prohibits any material or device placed over or around either plate that makes it illegible or harder to read. Both the front and rear plates must remain fully visible and legible at all times.

- Clear covers that reduce reflectivity or legibility of either plate under any conditions
- Frames that cover the state name, any character in the plate number, or any registration sticker on either plate
- Anti-camera sprays, reflective coatings, or plate-obscuring devices on either plate
- Dirt or debris that makes either plate unreadable – plates must be kept clean enough to be legible

Montana plate violations are traffic offenses with fines set by Montana courts. Fines vary by offense and jurisdiction.
What is the fine for a missing front plate or plate obstruction violation in Montana?

Altering or modifying a Montana license plate is prohibited by state law and carries penalties beyond a standard traffic offense.

No. Altering or defacing a Montana license plate is prohibited under Montana Code Annotated. Any plate that has been bent, painted, modified, or had unauthorized materials added is not valid and must be replaced. Plate alteration carries penalties that may exceed a standard traffic offense. Replacement plates are obtained at your county treasurer’s office.
Decorative Covers
Decorative plate covers of any kind are prohibited in Montana if they reduce the readability or reflectivity of either plate.
