What's the purpose of using turn signals?

1. To indicate speed to other drivers

2. To communicate your driving intentions to other road users

3. To signal an emergency

4. To alert pedestrians

The correct answer is: To communicate your driving intentions to other road users

Using turn signals is essential for communicating your driving intentions to other road users. When you use turn signals, you inform other drivers and pedestrians about your next move, such as turning or changing lanes. This communication helps to create a safer driving environment by allowing others to anticipate your actions, which can prevent accidents and misunderstandings on the road. For instance, if you're planning to make a left turn at an intersection, activating your left turn signal alerts other drivers that you are about to change your direction. This can influence their own decisions, such as whether to speed up, slow down, or wait for you to complete your turn. Effective communication through turn signals is a fundamental aspect of road safety and courteous driving behavior.
