Can cities ticket and assess penalties for having an expired license plate sticker in IA? OR, is it only the county treasurer that can impose a penalty for an overdue registration?

If I change county’s do I go to new countr greaser for tags

It is actually a State law. If the registration is expired, in order to renew the registration the penalty has to be paid in full. It is the Treasurer who is the collector of the penalty. Yes, if the registration is expired a city can ticket the owner of the registered vehicle.

What need to register vehicle from another state with 2 names on registration
