What must you do before turning left at an intersection?

Before turning left at an intersection, yielding to oncoming vehicles is crucial. This action ensures that you do not impede the path of vehicles coming from the opposite direction, which could potentially lead to a collision. When you're preparing to make a left turn, especially at an intersection where oncoming traffic may be approaching, assessing their speed and proximity helps determine if it is safe to execute your turn.

Additionally, yielding to pedestrians who may be crossing at or near the intersection is essential, as they have the right of way in most scenarios. This consideration enhances both your safety and that of others on the road, fostering a responsible driving environment.

While checking your rearview mirror and signaling your intent to turn are important aspects of safe driving, they do not take precedence over the necessity to yield to oncoming traffic when making a left turn. The priority in this situation is to ensure that the path is clear and that you are not putting yourself or others at risk.
