When is it required to use turn signals?

1. Only in heavy traffic

2. When making a turn or changing lanes

3. Before entering a roundabout

4. Every time you change speed

The correct answer is: When making a turn or changing lanes

Using turn signals is essential for indicating your intentions to other drivers and pedestrians, which helps ensure safety on the road. You are required to use turn signals when making a turn or changing lanes because these actions can significantly affect the movement of other vehicles and individuals sharing the roadway. Signaling your intent helps to prevent accidents by providing a clear warning to others about your planned maneuver, allowing them to react accordingly. While it may be tempting to think that turn signals are only necessary in specific situations, consistent signaling when turning or changing lanes is a fundamental rule of safe driving. It's worth noting that other situations, such as heavy traffic or approaching roundabouts, may call for signaling as well, but the primary and most straightforward requirement is to signal during turns and lane changes.
