When are you required to use turn signals?

Using turn signals is essential for communicating your intentions to other drivers on the road. The correct answer highlights that turn signals are required anytime you change directions. This includes not only making turns—both left and right—but also when changing lanes, merging into traffic, or entering and exiting any roadway.

Proper use of turn signals enhances safety by allowing other drivers and pedestrians to anticipate your actions, thus reducing the likelihood of accidents. It is a critical aspect of safe driving practices, emphasizing the importance of clear communication on the road. This response also encompasses scenarios that might not be as obvious to some drivers, like lane changes or navigating through roundabouts, making it crucial for all drivers to consistently signal whenever they alter their direction of travel.

Other choices may imply limited situations in which signaling is necessary, which doesn't encapsulate the full responsibility a driver has to inform others of directional changes.
