Massachusetts Permit Practice Test

If your turn indicating lights are broken, what is the correct hand-and-arm signal to indicate you are turning left?

1. Left arm straight out the window

2. Left arm bent up at the elbow

3. Right arm straight out the window

4. Right arm bent down at the elbow

The correct answer is: Left arm straight out the window

To indicate that you are turning left using hand-and-arm signals when the turn indicators are broken, you should extend your left arm straight out the window. This signal clearly communicates your intention to other drivers and pedestrians, making it an effective way to ensure safety on the road. The practice of using hand signals dates back to before cars had built-in turn signals, and it remains a standard for signaling turns. Extending the left arm straight outward is universally recognized as the indication for a left turn, providing clarity to others around you about your movements. This practice is especially important in scenarios where electronic lights may malfunction, as it maintains a safe environment by informing others of your intentions.
