Some states allow a left turn on red. When is this permitted?

Most US states permit a left turn on red only when both the street you are leaving and the street you are entering are one-way streets where the destination street's traffic moves to the right (in your direction). After a complete stop and yielding to all traffic and pedestrians, the left turn is allowed where state law permits and no sign prohibits it. A few states do not allow left-on-red at all; others allow it from a two-way street onto a one-way street. Check your specific state's rule. Even where permitted, left-on-red is unusual and not all drivers expect it; proceed with extra care. Posted signs override the default.
