Vietnamese authorities are warning motorcyclists against altering their vehicle license plates, including a recent trend of covering plates with purple decals. Any action that obscures, changes, or modifies the characters, numbers, or colors on a motorcycle plate is subject to penalties. This includes using stickers, masks, or technical devices to conceal the plate’s information. The regulations aim to ensure clear identification of vehicles for law enforcement and traffic management purposes. Violators could face fines of up to 6 million Vietnamese Dong (approximately $250 USD). Police are actively monitoring for such alterations and enforcing existing traffic laws. The crackdown underscores the importance of maintaining the integrity of vehicle identification for public safety and security.
