What is the purpose of using turn signals while driving?

Using turn signals while driving serves a crucial purpose: to signal other drivers about a change in direction. This is essential for maintaining safety on the roads, as it allows other drivers to anticipate the actions of the vehicle using the signals. By clearly indicating intentions to turn or change lanes, turn signals reduce the risk of accidents and promote smoother traffic flow.

Proper use of turn signals is not just a matter of courtesy; it is also a legal requirement in many jurisdictions, including Iowa. Failing to use turn signals can lead to misunderstandings among drivers, potentially resulting in collisions or dangerous driving situations. Therefore, signaling effectively contributes to the overall safety of the driving environment.

The other options, while they present ideas that might seem relevant at first glance, do not align with the fundamental function of turn signals in a driving context. They represent misconceptions about the purpose of this essential driving practice.
