Is the letter 'O' included in license plates?

License plates do not include the letter 'O' to prevent confusion with the number '0'. License plates are panels hung on the front and rear of vehicles, typically made of aluminum, sheet metal, plastic, or paper, and display the vehicle's registration number, registration region, and other relevant information. The primary function of a license plate is to identify the vehicle's region of registration and to trace the vehicle's owner and registration details through the plate number. The letters on license plates are assigned based on the prefecture-level administrative region where the vehicle is registered. The second letter of the license plate represents the code for the prefecture-level city, region, autonomous prefecture, or league, ranked according to the provincial vehicle management's division of administrative regions. The letter 'A' is designated for the capital city, provincial capital, or central urban area of a municipality directly under the central government, with subsequent letters assigned without a specific order.

I'm the kind of person who's fascinated by automotive details, and I always take an extra glance at license plates. The letter O is actually quite rare in license plates because it looks too similar to the number 0, which can easily cause confusion. For example, under blurry images from surveillance cameras, an O might be mistaken for a 0, potentially leading to incorrect tickets or disputes. I've studied China's license plate regulations, and the standard GA36 excludes easily confused characters like O and I. That's why you mostly see letters like P or Q on the road instead. This was considered during the design phase to reduce potential traffic hazards, especially at night or in poor weather conditions. Some car modification enthusiasts might want to use O for creative designs, but regulations directly prohibit it, ensuring the readability and practicality of the entire system. I think this is a smart choice that reflects meticulous engineering.

Having driven for two or three decades with plenty of experiences, it’s quite rare to come across license plates bearing the letter O. I remember once on the highway, spotting a plate that seemed to start with an O, only to realize up close it was the number 0—almost led to a misunderstanding in that moment. Many seasoned drivers know that to avoid confusion, the system skips letters like O during license plate design. At the DMV when registering, they’ll remind you to steer clear of easily confusable characters. Safety comes first, especially during rear-end collision investigations where clear license plate identification is key. I’d advise new drivers to pay extra attention to local regulations and avoid choosing ambiguous characters for the sake of uniqueness. I’ve seen some U.S. states use O, but it’s usually treated as a number—globally, the trend is to minimize ambiguity factors anyway.

From a regular car owner's perspective, the letter O on license plates is rarely encountered. The DMV regulations directly exclude it because O looks too similar to 0, which can easily cause misreading issues. For example, if there's a traffic violation and the camera can't clearly distinguish it, it could cause problems. In my daily driving experience, I've noticed that most license plates use other letters as substitutes to ensure clarity and safety. Simply put, it's a hassle-free design that's user-friendly for car owners.
