Left turn on red EXCEPT

• A. From a one-way street to another one-way street.
• B. From a two-way street to a one-way street.
• C. From a two-way street to a two-way street.
• D. From a one-way street to a two-way street.

Answer: (A)

Turning left on red is allowed only in a very specific situation: you may do it after you come to a complete stop, yield to all traffic and pedestrians, and only when you are turning from a one-way street onto another one-way street. In all other street-direction combinations, a left turn on red is not permitted.

So the scenario that fits this allowed exception is turning from a one-way street into another one-way street. The other setups—turning left on red from a two-way street to either a one-way or a two-way street, or turning from a one-way street to a two-way street—do not meet the exception and must follow the general rule against left turns on red unless a sign says otherwise. Always check for signs like “No Turn on Red” and proceed only if it’s clearly permitted.
