When should you use your turn signals?

Using turn signals is crucial for safe driving because they communicate your intentions to other drivers. They should be used before you change lanes, turn at an intersection, or merge into another lane. This allows other drivers to anticipate your movements, which helps to prevent accidents.

The correct choice emphasizes the importance of signaling not just when changing lanes but also when turning or merging, providing clear communication on the road. This practice fosters a safer driving environment by making your actions predictable to other road users.

Other options might limit the use of turn signals in ways that would not foster safety. For example, using them only in residential areas or exclusively when entering a roundabout does not address the full range of scenarios where signaling is necessary.
