In Maine, when is it legal to make a left turn at a red light?

Explanation

In many states, you may turn left on a red light in certain situations; typically, from a one-way street onto another one-way street. In Maine, however, left turns on a red light are always prohibited. Seven other states plus the District of Columbia also ban left turns on red. So does New York City, unless signs indicate otherwise. When traveling out of state, always check the local traffic laws.
