Is it mandatory to enter the left-turn waiting zone?

[VonBrooklyn]

The left-turn waiting zone is an area designated for vehicles waiting to make a left turn. The specific situation should be analyzed as follows: The correct way to navigate the left-turn waiting zone is: 1. When both the straight and left-turn signals in the same direction are red, left-turning vehicles are prohibited from entering the waiting zone and should queue behind the stop line until the signal changes. 2. When the straight signal in the same direction turns green, left-turning vehicles should enter the waiting zone in order and wait to make the left turn. 3. When the left-turn signal turns green, left-turning vehicles should proceed through the intersection in order. 4. When the left-turn signal turns red, any left-turning vehicles that have not yet entered the waiting zone should stop behind the stop line and wait, and must not enter the waiting zone.
