If you are turning right, you must come to a complete stop before the stop line and you can then proceed with your turn if traffic is clear. A stop is defined as a “complete cessation from movement.” In other words, your vehicle cannot be moving at all. You must yield to other vehicles entering the intersection on a green light and vehicles making U-turns. If you are travelling straight through the intersection or turning left then you cannot pass the stop line after the light turns red.
