I'm not surprised, it sounds illegal for the purpose you described. It's illegal just to own plate flipping devices without even using them in some states. Surely that would be too.

> A person commits an offense if the person with criminal negligence uses, purchases, possesses, manufactures, sells, offers to sell, or otherwise distributes a license plate flipper. An offense under this subsection is a Class C misdemeanor, except that the offense is a Class B misdemeanor if the person has previously been convicted of an offense under this subsection.

My intended used was for parked vehicles. Not to avoid moving violations.

I'm sure whoever makes plate flippers claims the same intended use.

edit - Found some for motorcycles on ebay...."Ideal for track days/shows/meets etc.." along with "FOR OFF ROAD USE ONLY" on the listings.
