Which statement about turning left on red from a two-way street onto a one-way street is true?

Which statement about turning left on red from a two-way street onto a one-way street is true?

• A. It is true to turn left on red when traffic and pedestrians are not present and there is no sign prohibiting turn on red
• B. It is never allowed
• C. It is allowed only when there is a dedicated left-turn-on-red phase
• D. It is allowed only when the cross street is also one-way

Answer: (A)

Left turns on red are allowed only when you’re turning from a one-way street into a one-way street, and only after you come to a full stop and yield to pedestrians and other traffic, unless a sign says otherwise. If you’re starting from a two-way street, turning left on red onto a one-way street is not permitted. The cross street being one-way is part of the condition, but the starting street also has to be one-way. A dedicated left-turn-on-red phase doesn’t override this street-configuration rule. So the maneuver is legal only when both streets involved are one-way and there’s no sign prohibiting the turn.
