Which of the following describes the action taken by a driver intending to merge left?

When a driver intends to merge left, signaling left is the appropriate action because it communicates the driver's intention to other road users. By using the left turn signal, the driver alerts pedestrians, cyclists, and other vehicles about the planned maneuver, which helps ensure safety and promotes coordinated movement on the road.

Merging requires clarity and predictability, so proper signaling is crucial to prevent misunderstandings that could lead to accidents. The left signal indicates not just the direction of the movement but also that there's a change in the flow of traffic, allowing others to react accordingly.

In scenarios where signaling is not utilized or is done incorrectly, such as signaling right when intending to go left, confusion can arise, causing potential collisions or disruptive traffic patterns. Proper signaling fosters safer driving practices and encourages responsible communication on the road.
