The primary purpose of turn signals is to indicate your intention to change lanes or turn. When drivers use turn signals, they communicate their planned movements to other road users, which is crucial for promoting safety and awareness on the road. Proper signaling allows other motorists, cyclists, and pedestrians to anticipate and respond to a driver's actions, helping to prevent accidents and misunderstandings.

When you activate your turn signal, you are effectively letting everyone around you know your next move, whether it's to merge into another lane or make a turn at an intersection. By doing so, you contribute to a smoother flow of traffic and reduce the potential for collisions resulting from sudden or unexpected maneuvers. This practice is not only a matter of courtesy but also a requirement of traffic laws in South Dakota and elsewhere.

The other options highlight aspects that are not related to the fundamental function of turn signals. Making a car look stylish is unrelated to safe driving practices, while alerting other drivers of your speed and notifying emergency vehicles focus on different forms of communication and do not pertain to the primary role of turn signals.
