What is required of drivers regarding the attachment of license plates?

Drivers are required to firmly attach license plates to their vehicles to ensure they are clearly visible and secure. This regulation is crucial because license plates serve as a primary means of vehicle identification for law enforcement and compliance with traffic laws. A securely attached plate reduces the risk of it falling off during transit, which could create hazardous situations for other road users. Additionally, a firmly affixed license plate helps authorities in accurately identifying vehicles for registration, taxation, and enforcement purposes.

The other options suggest alternatives that do not ensure the integrity and visibility of the license plate. For instance, adhesive materials may not provide the security needed for a license plate, and temporary removal could lead to identification issues. Altering plates can lead to legal penalties, as they must reflect the official registration information accurately. Thus, the requirement for plates to be firmly attached stands as a clear and important regulation in maintaining vehicle identification standards.
