When should you use your turn signal?

Using your turn signal is essential for safe driving and effective communication with other road users. The correct choice emphasizes that drivers should signal when changing lanes or making turns at intersections. This is because signaling indicates your intentions to other drivers, allowing them to anticipate your actions and react accordingly.

By using your turn signal when making these maneuvers, you enhance safety and reduce the likelihood of accidents. It's a standard part of defensive driving, ensuring that everyone on the road is aware of your next move.

While signaling when other cars are present (the first choice) may seem reasonable, it is important to signal regardless of whether other vehicles are around, as this practice helps establish a consistent routine. Additionally, although signaling is important on highways and when parking (the third and fourth choices), they are more specific situations where signaling is recommended rather than the fundamental rule of using your signals during turns and lane changes, which applies universally to all driving scenarios.
