Under Michigan rules, when is a left turn on red permitted?

• A. After the light turns green.
• B. After the light turns red.
• C. After a complete stop and when no sign prohibits it, and when it is safe to turn.
• D. Only when there is no oncoming traffic.

Answer: (C)

In Michigan, you may turn left on red after you come to a complete stop, only if there is no sign prohibiting the turn and the turn can be made safely. This means you yield to all traffic and pedestrians and check that there’s a clear gap before turning from a one-way street onto another one-way street. The idea is that the red light does not automatically prohibit a left turn in those precise conditions, but you must stop fully and ensure it’s safe.

That’s why the correct choice emphasizes stopping completely, checking for prohibitions, and ensuring safety before turning. Options that suggest turning after green, turning after the light is red without stopping, or turning when no oncoming traffic is present ignore the required stop, legality, or safety checks needed before making a left on red.
