I had the same problem, 2 yrs later I get a bill. So I call them and start fighting with them and the lady told me I would lose my license. I asked her to provide me with the proof that I was on there, she told me they take pics of the plates and would send me the copy of the pics. 2 weeks later she calls me and say not to worry about it, they could not find the pics anymore. The worst part was after i started to think about it more, I remembered that I had used the highway.
