In what scenario must you use your turn signals?

Using your turn signals is an essential part of safe driving, as it communicates your intentions to other road users and helps prevent accidents. Whenever you are changing lanes or turning, signaling is required regardless of the presence of other vehicles. This practice ensures that everyone on the road is aware of your actions, which aids in maintaining a smooth flow of traffic and enhances safety.

The requirement to signal applies at all times, regardless of the speed at which you are driving, the time of day, or the presence of other road users. This is why the option indicating that turn signals must be used whenever changing lanes or turning is the most accurate representation of the rules. Signaling is a fundamental aspect of defensive driving and contributes to road safety for all participants.
