Final answer:
When turning left, it is important to be vigilant for pedestrians, who are often struck by left-turning vehicles because they may be crossing the street where you are turning.
Step-by-step explanation:
When turning left, it is crucial to watch for pedestrians, who are often struck by vehicles making this maneuver. Pedestrians can be more difficult to see than other vehicles and may be crossing the street at the intersection where you are turning. When you turn left, you cross paths with pedestrians who have the right of way, and this is when most accidents can happen. Always be vigilant for pedestrians to prevent collisions and ensure their safety as well as yours.
