When should you use your turn signal?

Using your turn signal is essential for communicating your intentions to other road users while driving. The correct response highlights that you should activate your turn signal whenever you plan to change direction or speed. This means signaling not only when you are turning or changing lanes but also when you are merging, entering or exiting a highway, or even slowing down to allow for a turn.

Proper signaling enhances safety and facilitates smoother traffic flow by informing other drivers, cyclists, and pedestrians of your intended actions. It helps reduce the likelihood of confusion and unexpected maneuvers, which can lead to accidents.

The other options present more limited scenarios for using turn signals, which may not cover all necessary instances. While signaling for lane changes and turns is crucial, effective communication on the road encompasses any changes in direction or speed. Therefore, using your turn signal broadly whenever you plan to alter your intentions on the road is vital for responsible driving.
