What action should you take before making a left turn at an intersection?

Before making a left turn at an intersection, it is essential to yield to oncoming traffic and pedestrians. This action ensures that you are giving way to any vehicles approaching from the opposite direction, as well as to any pedestrians who may be crossing the road. Failing to yield could result in a collision, which can be dangerous for both drivers and pedestrians.

Yielding allows you to safely assess the situation and confirm that it is clear to proceed with your turn. It is important to ensure that you are making a safe maneuver that does not interfere with the rights of other road users. This is a fundamental rule of the road that promotes safety and helps to avoid accidents at intersections.

The other options present practices that are either unsafe or unnecessary, such as turning quickly which could block traffic or create dangerous situations, assuming that oncoming vehicles will stop, which could lead to collisions, and signaling right before a left turn, which could confuse other drivers about your intentions.
