I know how you feel. They only have the outline of the sign. I couldn't figure out the one for railroad tracks and I was almost in tears. There are no railroads anywhere around where I live. The examiner let it slide and gave me the answer. They give you a sheet with the signs on it beforehand or just ask for one. I just didn't really pay attention because I thought after driving for years, I knew it all! Don't worry, everybody's afraid of that darn test.
