Oh yes it most certainly is.
Why don’t you google it and educate yourself.
Really? Do you know a lot of people who were pulled over and ticketed because they didn't use their turn signal? I sure don't. I know perfectly well that it is a law on the books, but I have never heard of anyone getting pulled over with that as the primary reason. That doesn't mean it won't be included on the ticket if someone gets pulled over for something else and they also didn't use the turn signal. I could see them being pulled over for unsafe lane change--barging in front of another car, for instance, while not using the turn signal. Also, being taken to the police station and being booked over it? Nope, something doesn't smell right here.
