Q: A while ago you had offered a test that new drivers have to get 80% on in order to pass. But there were at least 2 signs I had never seen before. One was a circle with nothing in it and then a square with nothing in it. I'm wondering if there are other signs I've never seen before and was trying to find a place on the driver's web-site where I could look at all the signs and what they mean - however, I couldn't find it. I'm wondering if you could give me the url to that information.
