Always signal for any movement from moving straight ahead. It's a driving law in EVERY state in the U.S.
Unfortunately, you have these comments which are an indication of how poorly trained our point-and-hope steering chumps are......

I asked my sister and brother in law, both are police officers and they said that at least in Mass you don't have to when you are in a marked turn only lane. They may be wrong, but were in Mass so its not like anyone actually uses the turn signal anyway.
Here in colorado I don't believe it's illegal either, which is why I never got into the habit. I always signal when switching lanes and turning when not in a dedicated turn lane.
In both cases, the poster is woefully misinformed or just never really read his/her driver's manual, which covers the driving laws of his/her particular state.
Take the Mass comment......officers not knowing the law.
Here's what the Mass driver's manual states about it:
When you are traveling on a roadway, other people expect you to continue straight ahead, unless you indicate otherwise. This is why you must use signals whenever you make any move in traffic. Your signals notify pedestrians and other motorists of your intended moves and give them time to react.
Regardless of the kind of vehicle you are driving, you must use signals. If the electronic signals on your vehicle are not working, you must use the three hand signals shown in the margin. Signals should be made through the driver?s side window.
Mass. Driver's Manual, Ch. 4, pp. 89-90
Colorado is the same.
In urban or metropolitan areas, you must signal continuously for 100 ft. before making a turn or lane change. On four-lane highways where the posted speed limit is more than 40 m.p.h. you must signal for 200 ft.
Failing to signal is a traffic violation.
If your vehicle's turn signals do not work, you must use hand signals. If using hand signals, end your signal before starting to make your turn, and place both hands on the wheel while making your turn.
Colorado Driver's Manual, Ch. 10, p. 18
It's the law in every state and I doubt anyone can document differently.
Personally, I use them any time I move.....and after 39 years of driving, and having seen idiots that just swoop, zoom, and dart through traffic without using turn signals, I have no pity on them when they either get in an accident or are ticketed.
