I've got truck tags on my Silverado - reason being it's a 'second division' vehicle coming in at a certain weight break. A second division vehicle means a vehicle designed for carrying more than 10 persons, used for / as living quarters, and or used for pulling or carrying property, freight or cargo.
That said we also have farm truck plates (self explanatory, no? only exception being they are a not for hire truck), Mileage Tax exempt (charities / NFP's that put super low mileage on their trucks per year, think: shelters, salvation army, etc), Recreational Trailer (self explanatory), Flat Weight Trailers by weight break, Trailers by weight break (how my trailers are licensed), and Trucks.
That out of the way by having regular truck plates on my truck I am forbidden from driving on a lot of roads (parkways and things of that sort) as well as from parking in a *lot* of areas downtown. It's a pain in the rear, but you do what you have to do.
