That's exactly what I'm worried about...TX troopers use license plate recognition equipment. I was stopped once for not having insurance, but I had renewed it the day prior and the state data base was not updated yet. I'm certain that if they run my license plate they'll stop me...but the regs require that I display the paper tag in the rear window. RIGHT!!! With no rear window, I think I'll just cover my expired license plate with the paper one.
Cheers!
