Some intersections have separate traffic lights for left-turning traffic and for traffic going through the intersection or turning right.
When a left-turn green arrow appears for traffic in the left-turn lane, traffic going straight ahead or turning right will usually see a red light. You may turn left from the left-turn lane when you face a green arrow. Vehicles from the opposite direction may also be turning left.
After the left-turn green arrow, a yellow light appears for left-turning vehicles only.
After the yellow light, a red light appears for left-turning vehicles only. Traffic going straight ahead or turning right will face a green light or green arrows pointing straight ahead and to the right.
In these intersections, you may not begin turning left after the green light appears for traffic going straight ahead or turning right. If the light turns yellow while you are in the intersection, complete your turn with caution.
