Maybe so but I had NM plates. Maybe it was the out-of-state
road tax...
Nevada does that. They have what I call a "wasting fuel" fine. If you are doing, IIRC, 5 MPH over the speed limit(might be more)they stop you and issue you a ticket that only costs 15 bucks. They know you are going to pay it, instead of coming back to Nevada to contest it, the ticket doesn't go on your driving record either. They mostly use it on CA drivers.
The one time I got one I was doing 70 on a freeway, Nevada drivers were passing me like I was standing still and I'm the one the cop pulled over. I mailed in my 15 bucks and shrugged my shoulders, not much you can do about it.
