When is it appropriate to use turn signals?

Using turn signals is essential for ensuring safety on the road, as they communicate your intentions to other drivers and pedestrians. The correct response highlights that you should always signal before making a turn or changing lanes. This practice helps to prevent accidents by providing clear indications of your actions, allowing others to adjust their driving accordingly.

For instance, signaling before you turn lets cars following behind you know that you are about to change your direction, which can prevent collisions. Similarly, when changing lanes, a turn signal alerts nearby vehicles that you intend to move into a different lane, promoting smoother traffic flow and reducing confusion.

The other options do not encompass the full requirements for using turn signals. While it might seem like turning signals are only necessary for lane changes, they are equally important for turns. Signaling at a stop sign can be important for some situations, but the key is to signal proactively before the action, not just when approaching a stop. Moreover, turn signals are never optional; they must be used in all driving conditions, including residential areas, to uphold safe driving practices.
