What must be done according to the provisions relative to county name decals?

According to the provisions relative to county name decals, it is required to display the county name on license plates. This regulation is in place to ensure that vehicles can be easily identified in relation to their respective counties, facilitating law enforcement and administrative processes. The display of the county name serves several purposes including helping in the collection of road use taxes and enhancing local identification for various purposes.

The other options do not align with the specific requirements for county name decals. Changing residence upon moving pertains to requirements regarding vehicle registration and not directly to the display of county decals. Removing old decals before applying new ones could be advisable for clarity, but the core requirement focuses on the necessity to have the county name visible. Lastly, the requirement to register a vehicle every year is a separate administrative policy relating to vehicle ownership and does not specifically connect to the decal provisions. Thus, the emphasis on displaying the county name is the key takeaway in this context.
