Yes, in California (US), all motorcycles are required to have license plates and insurance stickers. This requirement is in accordance with the state's Department of Motor Vehicles (DMV) regulations.
Motorcycles, scooters, and mopeds are all considered two-wheeled vehicles under California law. Therefore, the same regulations apply to them regarding license plates and insurance. These vehicles must display a valid license plate, typically mounted on the rear of the vehicle, and have insurance coverage that meets the state's minimum requirements.
It's important to note that specific registration and insurance requirements may vary depending on the type of vehicle and its engine size. For instance, motorcycles with engines smaller than 150cc are exempt from certain registration requirements but still need a license plate and insurance.
To obtain more accurate and up-to-date information regarding the requirements for motorcycles, scooters, and mopeds in California, it is advisable to consult the California DMV or refer to their official website.
