What is the purpose of using turn signals?

Using turn signals serves the critical function of informing other drivers and road users of your intended actions on the road. This communication is essential for maintaining safety on the highways and city streets. When you signal, you give other drivers, cyclists, and pedestrians clear visibility into your movements, which helps prevent accidents and misunderstandings.

This use of signals aids in the smooth flow of traffic, allowing other drivers to anticipate changes in your direction, whether you're turning left, right, or changing lanes. By using turn signals, you are actively participating in a shared responsibility for safety on the road.

The other options do not align with the primary purpose of turn signals. Making a vehicle look stylish is irrelevant to driving safety, while increasing speed is not related to signaling intentions. Complying with passenger requests does not pertain to the fundamental function of turn signals, which is ultimately about communication with other road users.
