Using turn signals is crucial when changing lanes or making a turn because it communicates your intentions to other drivers on the road. This signaling helps ensure safety by allowing other road users to anticipate your actions, reduce the likelihood of collisions, and promote smoother traffic flow. Proper use of turn signals is a key aspect of responsible driving and is required by law.

While there are various situations where signaling may be important, such as during parking or when exiting a vehicle, the most critical moments are during lane changes and turns. This is when drivers need to make their movements clear to others, thereby enhancing overall road safety.
