When is it necessary to use your turn signals?

Using turn signals is essential for communicating your intentions to other drivers on the road. The correct choice indicates that you should signal when you are changing lanes or making a turn, as these actions impact the flow of traffic and help prevent collisions. When you signal during these maneuvers, it gives other drivers the information they need to anticipate your actions, allowing them to adjust their driving accordingly to maintain safety.

While there are specific circumstances where using turn signals becomes crucial—like lane changes and turns—other options suggest scenarios that are not universally applicable. For instance, signaling solely when driving at night does not encompass the full range of situations where signals are necessary. Similarly, the option stating to signal only when being followed by another vehicle limits the importance of signaling to a very narrow context, ignoring the overall responsibility of drivers to communicate their intentions to all road users. Thus, understanding the primary requirement to signal during lane changes and turns ensures adherence to road safety protocols.
