Yellow license plates appear in only a handful of U.S. states, and most of them are not states at all
True yellow plates — the bright, high-visibility kind — are issued by only a few jurisdictions in the United States. The most recognizable are New Hampshire, which uses white lettering on a yellow background for standard passenger plates, and North Dakota, which issues yellow plates with black lettering. Beyond those two, yellow plates are far less common than many people assume. Some states use yellow only for specific vehicle categories, like commercial trucks or taxis, rather than for all passenger vehicles.
The confusion often arises because yellow plates are more common in other countries — particularly across Europe and parts of Asia — where they serve as a standard format. In the United States, the dominant plate color scheme has historically been white with black lettering, or variations that include blue sections for state identification. Yellow plates stand out partly because they are unusual here, which is precisely why some states adopted them: the high contrast between yellow and black lettering improves visibility and readability, especially at night or from a distance.
Key Takeaways
- New Hampshire and North Dakota are the only two states that issue yellow plates as their standard passenger vehicle plates.
- Some states use yellow plates only for specific vehicle types, such as commercial trucks, taxis, or rental cars, not for all drivers.
- Yellow plates were adopted partly for safety reasons — the color contrast makes plates easier to read from a distance or in low light.
- Most U.S. states use white plates with black lettering, a format that has been standard for decades.
New Hampshire's yellow plates and the "Live Free or Die" standard
New Hampshire issues yellow plates with black lettering to all passenger vehicles registered in the state. The plate format includes the state name, the vehicle registration number, and the state motto "Live Free or Die" at the top. This has been New Hampshire's standard plate design for many years, making it one of the most visually distinctive plate formats in the country.
The yellow background serves a practical purpose in New Hampshire's climate. The state experiences heavy snow and road salt exposure, and the high contrast between the yellow plate and black lettering remains legible even when plates accumulate road grime or salt spray. Drivers from other states often notice New Hampshire plates when ready, both because of the color and because of the distinctive motto.
North Dakota's yellow plates and commercial vehicle use
North Dakota issues yellow plates with black lettering as its standard passenger plate format. Like New Hampshire, North Dakota adopted yellow partly for visibility reasons, particularly given the state's weather conditions and long stretches of highway where distant plate recognition matters.
North Dakota plates also carry the state name and registration number in the standard format. The yellow-and-black combination has been part of North Dakota's vehicle registration system for a considerable time, and the state has maintained this format through multiple design updates.
States that use yellow plates for specific vehicle categories
Several states issue yellow plates only for certain types of vehicles rather than as a universal standard. Taxi cabs in many states, including New York and California, carry yellow plates to make them when ready recognizable to passengers and law enforcement. This is a practical choice: yellow plates help distinguish licensed taxis from private vehicles and ride-share services.
Commercial trucks and commercial vehicles in some states use yellow plates to indicate they are registered for business use rather than personal transportation. The specific rules vary by state and by vehicle weight class. Some states reserve yellow for vehicles above a certain gross vehicle weight rating (GVWR), while others use it for any vehicle registered under a commercial license plate category.
Rental cars in a few states carry yellow plates or yellow-tinted plates to identify them as rental fleet vehicles. This helps law enforcement and other drivers quickly identify rental vehicles on the road. The practice is less common than it once was, as many states have moved away from special rental car plate formats.
Why most states do not use yellow plates
The white-and-black plate format became the American standard partly through historical accident and partly through practical choice. When vehicle registration systems were first standardized in the early 20th century, white plates with black lettering were adopted as the default. Over time, this became the norm, and most states have maintained it for consistency and familiarity.
Yellow plates do offer visibility advantages, but they also present challenges. Yellow plates can fade or discolor more noticeably over time, especially in harsh sunlight or in states with significant UV exposure. The dye used in yellow plates can also be more expensive to produce than the standard white-and-black combination. Additionally, once a state chooses a plate format, changing it requires replacing millions of plates over time as vehicles are re-registered, which is a substantial logistical and financial undertaking.
Many states have experimented with other high-visibility formats instead of yellow. Some use white plates with reflective backgrounds, or they add colored sections (like the blue stripe used by many states for federal compliance with the Real ID Act). These alternatives provide visibility improvements without the full switch to yellow.
How to identify a vehicle's state of registration by plate color
Plate color alone is not always a reliable way to identify a vehicle's state of registration. While New Hampshire and North Dakota are known for yellow plates, many other states use variations of white, blue, and reflective backgrounds. Some states have redesigned their plates multiple times, and older plates may look different from current ones.
A more reliable method is to look at the state name printed on the plate itself, which is required on all U.S. license plates. The state abbreviation or full name will always appear on the plate, usually at the top or along the left edge. The plate format, colors, and design elements can vary, but the state identification is always present and clearly marked.
Special plates and vanity plates across states
Beyond standard registration plates, many states offer specialty plates and vanity plates that allow drivers to customize their registration. These plates may use different color schemes, backgrounds, or designs to support specific causes, organizations, or personal preferences. Some specialty plates are issued to support state parks, wildlife conservation, military service, or other causes, and they may use colors different from the state's standard plate format.
Vanity plates — plates with custom lettering chosen by the driver — are available in most states and typically follow the state's standard color scheme. However, some states allow vanity plates to use alternative designs or colors as part of the customization process. The rules for specialty and vanity plates vary significantly by state, so a driver interested in a custom plate should check their state's Department of Motor Vehicles website for current options and costs.
Frequently Asked Questions
Are yellow license plates legal in all states?
Yellow plates are legal in the states that issue them as standard (New Hampshire and North Dakota) and in states that use them for specific vehicle categories like taxis or commercial trucks. If you are registering a vehicle in a state that does not issue yellow plates, you cannot obtain a yellow plate for standard passenger use. However, you may be able to get a specialty plate with alternative colors depending on your state's options.
Can I get a yellow plate if I move to a state that does not use them?
No. Your license plate format is determined by the state where you register your vehicle. If you move to a state like California or Texas that uses white plates, your new registration will be issued on a white plate. You cannot choose to keep a yellow plate from your previous state once you register your vehicle in a new state.
Why do taxi cabs have yellow plates?
Yellow taxi plates make licensed cabs when ready recognizable to passengers and law enforcement. The bright color helps distinguish taxis from private vehicles and ride-share services. This system has been used in major cities for decades and remains standard in most places where taxis operate.
Do other countries use yellow license plates?
Yes. Yellow plates are standard or common in many countries, including much of Europe, parts of Asia, and other regions. The format and meaning vary by country — some use yellow for all vehicles, while others reserve it for specific categories. The United States is unusual in its preference for white plates as the standard format.
Can I order a custom yellow plate in a state that does not use them?
Most states do not offer yellow as an option for custom or vanity plates if it is not part of their standard format. However, some states do allow specialty plates with alternative colors for specific causes or organizations. Check your state's Department of Motor Vehicles website to see what custom plate options are available in your area.
