It was tongue in cheek...so to speak. DPS, like any law enforcement agency can find PC for virtually ANY vehicle rolling down the road.

"Hmmmm.....Mr. Smith, your plate appeared to me like it MAY have been modified, sorry for the inconvenience, but ya can't be too careful about these things" or "Mr. Pickup driver.....it appeared to me that you May have had some debris blow out of the cargo area of your truck....need to keep an eye on that"

And TPWD.....those guys have FAR reaching jurisdiction, again they have to have probable cause,....but John Q's idea of PC and their idea of it are two completely different things when it is two in the morning and you are on the side of the road with the red & blues in the rearview.

if you have a Texas Drivers License, or Texas Vehicle Registration, you have for all intent and purpose given Texas DPS probable cause to pull you over at any time.
Same situation with TX Parks and Wildlife....you got a huntin license....you have given consent to search your vehicle, residence,etc.......at any point, anytime that your license is in effect.
