What is a key reason for using turn signals?

A key reason for using turn signals is to alert other drivers of your intended actions. This communication is essential for ensuring safety on the road, as it helps to prevent confusion and potential accidents. When you signal your intention to turn or change lanes, other drivers can anticipate your movements and adjust their driving accordingly.

Additionally, using turn signals is also a legal requirement in most jurisdictions. Failing to signal can lead to traffic violations and penalties, further emphasizing the importance of this practice in responsible driving.

Though entertaining passengers may be an aspect of driving, it does not pertain to the critical functions of turn signals. Overall, signaling is a vital habit that supports both effective communication on the road and adherence to traffic laws.
