When should you use your turn signal?

Using your turn signal is an important part of safe driving as it communicates your intentions to other drivers and pedestrians. The correct choice emphasizes that you should activate your turn signal when changing lanes, merging into traffic, or making a turn. This practice is essential for ensuring that other road users are aware of your movements, which can significantly reduce the risk of accidents.

By signaling when changing lanes, you inform nearby drivers of your intent to shift your position on the roadway, which enables them to react appropriately. Similarly, merging into traffic requires signaling to ensure that other vehicles can adjust their speed or position to accommodate your entry into their lane. Finally, using a turn signal while making a turn clearly indicates your actions, allowing other road users to anticipate your maneuver and respond safely.

In contrast, signaling when driving straight, only at traffic lights, or while parking in a lot does not encompass the full range of situations where it is essential to indicate your intentions. These situations could lead to confusion and miscommunication among drivers, which can compromise safety on the road.
