Most states require at least a driver side mirror. My uncle found this out the hard way on his truck. When he bought it the mirrors weren't installed. He never bothered to put them on because it looked good without them. Needless to say he got pulled over. He didn't get a ticket, but was told he had to have them. He called other local, and state law enforcement agencies and got differing answers to the question. So it's really up to the officer to whether it is enforced or not.
