When is it permissible to make a left turn at a traffic signal?

Making a left turn at a traffic signal is permissible when the signal is green, provided that you yield to any oncoming traffic and pedestrians. A green signal indicates that you can proceed with caution; however, it is crucial to check for other vehicles and ensure the path is clear before completing the turn. This ensures the safety of all road users and complies with traffic regulations.

While a left turn signal specifically gives permission for such a maneuver (which is the first choice), it is not the only scenario where a left turn can be made legally. Additionally, a stop sign is not relevant for making a turn at a traffic signal, and while a yellow light may suggest caution, it typically indicates that the signal is about to change to red and implies that vehicles should prepare to stop, not proceed with a left turn.
