How illegal to drive thru toll without paying?
A while back I went to another city, more than 180 miles away to buy a car.  My dad drove me there.  We never been there before.  I got the car from an individual, so I didn't get any paper tags.  The state does not require registration for 7 business days, but it does require insurance.  I did get insurance before driving.
Anyways, we apparently took an unmanned toll road because my dad got a bill in the mail with a picture of his plates.  The car I drove had no plates, not even paper ones so I got nothing.  I don't plan on doing this again, I didn't know we took a toll road.  But my question is, how illegal was it for us to take an unmanned "photographical" toll road without any plates?
P.S. I paid my dad's toll bill.
