Oklahoma's lawmakers don't have much room to complain when it comes to Sooners buying cheaper car tags in Oregon and Texas, an area truck driver said.

The Legislature passed a law in the 1980s making Oklahoma a ``registration friendly'' state for trucking companies across America. The Oklahoma law undercuts tag registration fees of big rigs in other states and has spawned commercial registration outfits here that make as much as $500 for each vehicle they register. The Oklahoma Tax Commission's share is about $450 per tractor-trailer.

Companies such as Interstate Carrier Services Inc. and PROCERT Inc. routinely place ads in trucker mailers, touting Oklahoma's low registration cost.

One Interstate ad reads: ``Why Do So Many Motor Carriers Have Oklahoma Tags? No Sales Tax! No Personal Property Tax! CALL TODAY!

``Sounds like Oregon, doesn't it?,'' said Pat, an independent truck driver who asked to remain anonymous. ``The Legislature wants to whine about what's happening in Oregon and Texas when we're doing the same or worse. We don't have any room to talk.''
