What is the purpose of turn signals?

Turn signals play a crucial role in road safety by conveying the driver's intentions to other road users. Their primary purpose is to indicate when a vehicle is about to turn or change lanes. By using turn signals, drivers communicate their upcoming maneuvers, which allows other drivers and pedestrians to anticipate and respond appropriately. This helps prevent accidents and increases overall safety on the road.

While warnings to pedestrians about the presence of a vehicle, communicating speed to other drivers, or signaling for emergency assistance are important aspects of driving, they do not encompass the main function of turn signals. Turn signals are specifically designed for communicating directional changes, making them an essential tool for safe driving practices.
