You may make a left turn at a red light if you are turning from

In Massachusetts, you are allowed to turn left on a red light from a one-way street onto another one-way street unless signs prohibit it. Before making the left turn, you must come to a complete stop and then yield to pedestrians and oncoming traffic. (Note: The laws about left turns on red are different in some other states. Some states also allow left turns on red from a two-way street onto a one-way street. On the other hand, some other states prohibit left turns on red altogether. So does New York City, unless signs indicate otherwise. When traveling out of state, always check the local traffic laws.)
