Hawaii License Plate Laws

Hawaii requires most passenger vehicles to display two license plates, one on the front and one on the rear of the vehicle. State law also regulates how plates must be mounted, when they must be illuminated, and what types of covers, frames, or accessories are allowed.

Although each Hawaii county operates its own vehicle registration office, license plate display laws are generally consistent across the state. Failing to properly display your license plates can result in citations, equipment violations, or court-imposed fines.

This guide explains Hawaii’s current license plate laws, including front plate requirements, plate frame regulations, obstruction rules, registration stickers, and common violations.

Does Hawaii Require a Front License Plate?

Yes. Hawaii requires both a front and rear license plate for standard passenger vehicles.

The front plate must be securely attached to the front of the vehicle, while the rear plate must be mounted on the rear. Both plates must remain clearly visible and legible at all times.

Driving with only a rear plate or removing the front plate is considered a traffic violation.

Vehicles that typically require two plates include:

• Passenger cars
• SUVs
• Pickup trucks
• Vans
• Most commercial vehicles

Certain specialty vehicles, trailers, or motorcycles may follow different registration requirements.

How Must License Plates Be Displayed?

Both license plates must be:

• Securely fastened to the vehicle
• Mounted in the designated front and rear locations
• Installed horizontally
• Clearly visible and readable
• Free from damage or excessive bending

Drivers should not mount plates inside the windshield, dashboard, rear window, or any alternative location that reduces visibility.

Improper mounting may result in an equipment or registration violation.

Are License Plate Covers Legal in Hawaii?

License plate covers are only legal if they do not interfere with the visibility or readability of the plate.

Many aftermarket covers marketed as “clear” or “protective” can create glare or reduce reflectivity under headlights or camera systems. If a cover makes any part of the plate harder to read, it may violate Hawaii law.

Covers that may be considered illegal include:

• Tinted covers
• Smoked plastic covers
• Dark acrylic shields
• Mirrored or reflective covers
• Any cover that obscures numbers or letters

The safest way to remain compliant is to display the plate without any cover.

Are Tinted License Plate Covers Legal?

No.

Tinted or colored license plate covers that reduce visibility, contrast, or reflectivity are prohibited.

Law enforcement officers must be able to read the entire plate during both daylight and nighttime conditions.

Are License Plate Frames Legal in Hawaii?

Yes, but only if the frame does not block any required information on the plate.

A legal frame must leave completely visible:

• Every letter and number
• The state name
• Registration stickers
• Validation decals
• Any other identifying information printed on the plate

Decorative frames that partially cover any portion of the license plate may result in a citation.

Can Decorative License Plate Covers Be Used?

Decorative covers are generally not recommended.

Even transparent decorative covers may become illegal if they reduce:

• Legibility
• Reflectivity
• Visibility from different angles

If there is any doubt, removing the cover is the safest option.

What Counts as License Plate Obstruction in Hawaii?

A license plate is considered obstructed whenever anything prevents it from being clearly identified.

Common examples include:

• Tinted or smoked covers
• Dirty or mud-covered plates
• Snow or debris covering characters
• Folded or bent plates
• Frames hiding letters or stickers
• Plastic shields causing glare
• Anti-camera sprays or coatings
• Objects mounted in front of the plate

Drivers are responsible for keeping both license plates clean and readable whenever operating the vehicle.

Does Hawaii Require a Rear License Plate Light?

Yes. The rear license plate must be illuminated with a white light whenever the vehicle’s headlights or parking lights are on.

The light must make the rear plate readable from at least 50 feet behind the vehicle.

A burned-out license plate light can lead to an equipment violation and should be replaced promptly.

Hawaii Registration Sticker Requirements

Hawaii issues annual registration decals that must remain properly attached to the rear license plate.

Requirements include:

• Display the current registration sticker.
• Do not alter or remove the sticker.
• Replace damaged or missing stickers through your county motor vehicle office.
• Follow county instructions for sticker placement.

Driving with an expired or improperly displayed registration sticker may result in a citation.

Can You Modify a Hawaii License Plate?

No. License plates are official government-issued identification and may not be altered.

Examples of prohibited modifications include:

• Painting the plate
• Cutting or trimming the plate
• Bending the plate
• Drilling additional holes that obscure information
• Covering numbers or letters
• Applying decals over the plate

If a plate becomes damaged or unreadable, it should be replaced through your county registration office.

Common Hawaii License Plate Violations

Drivers may receive citations for violations such as:

• Missing front license plate
• Missing rear license plate
• Obstructed license plate
• Illegal plate cover
• Illegal plate frame
• Dirty or unreadable plate
• Improper mounting
• Burned-out license plate light
• Expired registration sticker
• Altered or damaged plate

Keeping both plates clean, visible, and properly mounted helps avoid unnecessary traffic stops.

Hawaii License Plate Violation Fines

Specific penalties vary depending on the violation and the county court handling the citation.

Because Hawaii courts determine penalties based on the specific offense, the total fine may vary.
