YOU CAN TURN LEFT ON RED IN THE MICHIGAN U

Why is know one doing this? If a sign is not posted that prohibits a left on red, then it is perfectly legal to make a left on red (after you come to a complete stop). I am tired of sitting at the light and honking at the guy/girl in front of me to go, because I normally get the finger or a strange look.  Please read below, I cannot paste in bold but it is clear as day in the Maryland law that this is perfectly legal. Now please stop wasting my time and make a left on red in the Michigan UMd.
