What left turns are areas for turning that are controlled by a traffic signal or traffic sign?

Left turns that are controlled by a traffic signal or sign typically occur at intersections where specific rules govern the movement of vehicles. These signals or signs may indicate when it's safe to turn left, often requiring drivers to yield to oncoming traffic or pedestrians. Additionally, some intersections may feature dedicated left turn lanes with their own signals, allowing for more efficient traffic flow. Proper adherence to these signals is crucial for maintaining safety on the road.
