When a Cop stopped me. I had just purchased, a few hours previous, a used vehicle. It was late afternoon, and the dealer had run out of temp tags. On the way home, I decided to stop for some food and see some friends. After leaving my friends I headed straight home by way of Interstate 70. He stopped me for not having tags displayed. I explained the situation to him and showed him the paperwork. I still got a ticket for failure to display a tag. You win some and you lose some. I think my civil rights were violated somehow.
