You can use that excuse, but all an officer has to do is run your license plate and the return gives him a wealth of information. Of which I will not disclose. All I am saying if you lie and get caught, get ready.
RDJ is pretty much right, it is normally my fellow brothers who enforce this law, stupid or not.
I keep hoping that the Texas Lawmakers will take a few minutes out of their busy BBQ eating and good'ole boy backslapping to change the law to require only a single plate. I would be more than happy to pay the same as I am paying now even if I was only issues one plate LOL!
