When turning left on a red light, under which conditions is this allowed?

• A. When turning from a one-way street onto another one-way street and there is no sign prohibiting it, and it is safe.
• B. Always allowed.
• C. Never allowed.
• D. Only when there is a green arrow.

Answer: (D)

You can turn left on red only in specific conditions: you must be on a one-way street turning onto another one-way street, you come to a full stop, you yield to pedestrians and other traffic, and there is no sign that prohibits the turn. If any of these conditions aren’t met—such as a sign forbidding left turns on red, or the path isn’t clear—the turn isn’t allowed. The presence of a green arrow isn’t what makes a left on red possible; a green arrow provides a protected turn, but you can still turn on red in the allowed one-way-to-one-way scenario even without a green arrow. Always check for prohibiting signs and ensure the way is clear before proceeding.
