Final answer:
To make left and right turns at a controlled intersection, observe the traffic signals and signs, follow the correct procedures for signaling and positioning, and yield to oncoming traffic, pedestrians, and bicycles.
Step-by-step explanation:
To make left and right turns at a controlled intersection, drivers must first observe the traffic signals and signs. When making a left turn, it is important to stay in the lane closest to the middle of the road, signal your intention to turn well before the intersection, and yield to oncoming traffic and pedestrians. Once the way is clear and the traffic signal permits, complete the turn into the lane closest to the center median. For a right turn, stay in the far right lane, signal your intention, and check for pedestrians and bicycles. Slow down and turn into the right lane of the road you are entering, making sure not to cut the corner too sharply. A traffic signal at an intersection assists in managing traffic flow and pedestrian safety, allowing for safer crossing and better organized turns for vehicles.
