Which of the following describes proper use of turn signals?

The proper use of turn signals is to indicate your intention to other drivers and pedestrians before making turns or lane changes. Signaling in advance ensures that those around you are aware of your actions, which is essential for maintaining safety on the road. It helps prevent accidents by providing crucial information about your movements.

Using turn signals only when no other vehicles are around does not enhance safety, as signaling is primarily meant to communicate with other road users. Signal use when driving in reverse is important, but the key is that it’s meant for turning or changing lanes while moving forward. Additionally, signaling while parked does not serve a purpose unless you are maneuvering out of the parking space. Hence, the best practice is to always signal before making turns or lane changes, as indicated in this option.
