South Carolina Driver's Permit Practice Exam

When should you use your turning signals?

1. Only when overtaking another vehicle

2. Before parallel parking, changing lanes, or turning at an intersection

3. Only when required by law

4. Whenever you see a police officer

The correct answer is: Before parallel parking, changing lanes, or turning at an intersection

Using your turning signals before parallel parking, changing lanes, or turning at an intersection is essential for safe driving and effective communication on the road. Signals are a way to inform other drivers and pedestrians about your intended actions, which helps prevent accidents and misunderstandings. When you signal your intention to change lanes or make a turn, you give other road users the opportunity to adjust their behavior accordingly. This is particularly important in busy traffic situations, where your actions can directly impact the safety of those around you. Signaling before you park can also make your intentions clear to drivers behind you, reducing the likelihood of a rear-end collision. The requirement to signal is not only a matter of courtesy but also a fundamental rule of the road, aimed at promoting safety and order in traffic, regardless of the specific laws of each jurisdiction. This practice is a key aspect of defensive driving, where anticipating the actions of other drivers can significantly reduce risks on the road.
