If you’ve ever noticed the license plates on cars in Hawaii, you may have wondered why they all start with the letter L. There’s actually an interesting history behind this unique quirk of Hawaii license plates.

If you’re short on time, here’s a quick answer to your question: Hawaii license plates start with L because it stands for the island of Oahu, which is where Honolulu and the majority of Hawaii’s population is located.

The History of Hawaii License Plates

License plates are a ubiquitous part of our daily lives, and they serve as a unique identifier for our vehicles. But have you ever wondered why Hawaii license plates start with the letter “L”? The history of Hawaii license plates is an interesting one, with a rich story behind it. In this article, we will delve into the origins of Hawaii’s license plate system and explore the meaning behind the prefix “L”.

How Hawaii’s Current License Plate System Began

The current license plate system in Hawaii was introduced in 1961. Prior to that, Hawaii had a different system in place, where license plates consisted of a number followed by one or two letters. However, as the number of registered vehicles in the state increased, it became necessary to introduce a new system that could accommodate the growing demand.

The decision was made to adopt a three-letter, three-number format for Hawaii license plates. The first letter in the sequence was designated to represent the county where the vehicle was registered. The second and third letters were randomly assigned, while the first number represented the year the license plate was issued. This new system allowed for a greater number of combinations, ensuring that there would be enough unique license plates to go around.

The Meaning Behind Hawaii’s License Plate Prefixes

Now, let’s explore the meaning behind the prefix “L” that is found on all Hawaii license plates. The letter “L” stands for “Leeward,” which refers to the western side of the Hawaiian Islands. The Leeward side is known for its beautiful beaches, stunning sunsets, and vibrant communities.

The choice of the letter “L” as the prefix for Hawaii license plates was not arbitrary. It was a deliberate decision to showcase the unique identity of the state and its connection to the Leeward side. This prefix serves as a symbol of pride for the residents of Hawaii and represents the beauty and diversity of the islands.

So, the next time you see a Hawaii license plate starting with the letter “L,” remember the rich history and meaning behind it. It is a small but significant detail that reflects the unique culture and geography of the Hawaiian Islands.

Oahu and the Letter L

Have you ever wondered why Hawaii license plates start with the letter L? Well, the answer lies in the beautiful island of Oahu, which is the heart of the Hawaiian archipelago. Oahu is not only the most populous island in Hawaii but also the location of the state capital, Honolulu. The letter L is an abbreviation for “Oahu” and is used to designate vehicles registered on this island.

Unique Identification System

Hawaii has a unique vehicle identification system that assigns a letter to each of its major islands. Apart from Oahu, the other islands are represented by different letters. For example, the letter H is used for the Big Island (Hawaii), the letter M for Maui, and the letter K for Kauai. This system helps easily identify where a vehicle is registered and provides valuable information to law enforcement agencies and other relevant authorities.

Honoring Tradition

The use of the letter L to represent Oahu on license plates is not just a practical consideration but also a way to honor the island’s rich history and cultural heritage. Oahu is home to Pearl Harbor, which played a significant role in World War II. It is also known for its stunning beaches, vibrant city life, and iconic landmarks like Diamond Head. By associating the letter L with Oahu, Hawaii pays homage to the island’s contributions and unique character.

Other Interesting Facts

Did you know that the letter L is not the only one used for Oahu license plates? In addition to L, you may also find the letters E, G, and H on some plates. These letters indicate specific vehicle types or classes, such as electric vehicles (E), government vehicles (G), or vehicles for hire (H). So, if you see a license plate starting with L, E, G, or H in Hawaii, you can be sure it is registered on the island of Oahu.

Exceptions to the L Prefix Rule

While it is true that most license plates in Hawaii start with the letter “L,” there are a few exceptions to this rule. These exceptions exist to accommodate specific groups or individuals who require a different type of license plate for various reasons.

License Plates for Government Vehicles

One exception to the L prefix rule is for government vehicles in Hawaii. Government vehicles, such as those used by state agencies, law enforcement, or emergency services, have license plates that start with different letters. For example, plates for state-owned vehicles typically start with the letter “S,” while plates for county vehicles might start with the letter “C.” This allows for easy identification and differentiation of government vehicles on the road.

Special and Personalized Plates

Another exception to the L prefix rule is for special and personalized license plates. Hawaii offers a variety of specialty plates that allow drivers to personalize their vehicles. These plates can feature custom letter and number combinations, as well as unique designs that reflect personal interests or affiliations. Examples include plates for veterans, military personnel, or specific organizations. These special plates may start with letters other than “L,” depending on the specific design or customization chosen by the driver.

It’s important to note that while these exceptions exist, the majority of license plates in Hawaii still start with the letter “L.” This unique identifier has become a recognizable symbol of Hawaii’s vehicle registration system and is often associated with the state’s vibrant culture and beautiful landscapes. So, next time you see a license plate with the letter “L” in Hawaii, you can appreciate its significance within the broader context of the state’s license plate system.

Pros and Cons of Hawaii’s License Plate System

Benefits of Location-Based Prefixes

Hawaii’s unique license plate system, starting with the letter “L,” has several advantages. One of the primary benefits is that it helps identify where a vehicle is registered. This information is particularly useful for law enforcement agencies, as they can quickly determine the origin of a vehicle by looking at the license plate. For example, if a vehicle with an “L” prefix is involved in a hit-and-run incident, authorities will know that it is registered in Hawaii.

Another advantage of the location-based prefix is that it allows for easier tracking of vehicle ownership. By associating a specific prefix with a particular county or island within Hawaii, it becomes simpler to identify the owner’s residence. This information can be valuable in cases where a vehicle needs to be traced back to its owner for legal or administrative purposes.

The location-based prefix also adds a touch of uniqueness and pride for Hawaii residents. It creates a sense of belonging and serves as a symbol of the state’s identity. Seeing a license plate starting with “L” can evoke a feeling of connection and community among Hawaii drivers, fostering a sense of camaraderie on the roads.

Criticisms and Confusion

Despite its benefits, Hawaii’s license plate system does have some drawbacks. One of the main criticisms is the potential for confusion when identifying vehicles from other states or jurisdictions. Visitors or newcomers to Hawaii may mistakenly assume that all Hawaii license plates start with “L,” leading to misunderstandings or difficulties in identifying non-resident vehicles.

Additionally, the location-based prefix can make it challenging to discern the age of a vehicle. Some states use a sequential numbering system, where the higher the number, the newer the vehicle. In Hawaii, however, the numbering system is not related to the age of the vehicle. This can cause confusion when trying to determine the vehicle’s model year based solely on the license plate.


In summary, Hawaii license plates start with the letter L because it represents the island of Oahu, home to the state’s capital and largest population center. While this prefix system has its benefits, it has also created some confusion and criticism over the years. Nonetheless, the aloha spirit and tropical locale of Hawaii continue to make even mundane things like license plates unique in their own charming way.
