What factors should drivers consider before making a left turn at an intersection?

The correct answer emphasizes the comprehensive evaluation drivers must perform before executing a left turn at an intersection. When making this maneuver, drivers should be aware of oncoming traffic to avoid collisions, as vehicles may be approaching from the opposite direction. Additionally, it’s crucial to look out for pedestrians who might be crossing the intersection or waiting to cross, as their safety is a priority. Finally, existing traffic signals play a significant role in guiding the action—drivers need to ensure that the signal allows for a left turn and that it is safe to proceed.

Considering only traffic signals, the color of the traffic light, or factors like the time of day and road speed limit does not provide a complete picture, as these elements do not address the immediate situational awareness required to ensure safety when navigating an intersection. Thus, the correct answer encompasses a broader range of critical factors necessary for making a safe left turn.
