Idaho Written Driver's License Practice Test

When faced with a green arrow and a red light at an intersection, the correct course of action is to recognize that the green arrow indicates a permissive movement in the direction it points, while the red light governs the overall traffic signal. In this situation, the green arrow specifically allows you to turn left, regardless of the red light. However, if you wish to go straight ahead, that is not permitted unless another signal indicates otherwise. It's essential to remember that while the green arrow enables you to make a left turn, this does not mean that any other movements—like proceeding straight—are allowed against the red light unless specifically signaled. Additionally, if you're turning left, you must always be cautious and yield to any oncoming traffic and pedestrians who may have the right of way.
