What is the purpose of using turn signals while driving?

Using turn signals while driving is essential for safety and communication on the road. When you signal before making a turn or changing lanes, you are alerting other drivers and road users of your intentions. This communication helps prevent accidents by allowing others to anticipate your movements and react accordingly. It fosters a safer driving environment, as everyone on the road is aware of their surroundings and can make informed decisions based on your signals.

The other options do not serve this crucial function. Styling your car or expressing frustration does not promote safe driving practices or enhance communication among drivers. Speed regulation is unrelated to the use of turn signals, as signaling is specifically intended to inform others about changes in direction rather than control speed.
