What should you do when you want to make a left turn?

  1. Sound your horn

  2. Signal with your headlights

  3. Signal with your arm

  4. Signal with your turn signal

The correct answer is: Signal with your turn signal

When making a left turn, it is important to use your turn signal to indicate to other drivers that you intend to turn left. Using your horn or headlights will not communicate your intention to turn left and could potentially confuse or startle other drivers. Additionally, signaling with your arm may not be visible to all drivers and is not as clear as using a turn signal. Therefore, the best option when making a left turn is to use your turn signal.
