What is the function of turn signals in a vehicle?

The function of turn signals is primarily to indicate a driver's intention to turn or change lanes. This communication is essential for maintaining safety on the road, as it allows other drivers and pedestrians to anticipate the vehicle's movements. By signaling, drivers can reduce the risk of potential accidents caused by sudden maneuvers that may catch others off guard.

Effective use of turn signals creates a better flow of traffic and promotes safer driving practices. The clear visual cue provided by the turn signals ensures that everyone on the road is informed of a driver's intended actions, helping to prevent misunderstandings and facilitating smoother transitions between lanes or between turns.

The other options serve different purposes or do not accurately represent the primary function of turn signals. While notifications of vehicle malfunctions and warnings to pedestrians are important, they are not the core purpose of turn signals. Additionally, the idea that turn signals are merely decorative undermines their critical role in traffic safety.
