When must you use turn signals while driving?

Using turn signals is an essential part of safe driving as it communicates your intentions to other road users. The correct answer highlights that turn signals must be used when making a turn or changing lanes. This requirement is in place to alert other drivers, cyclists, and pedestrians about your actions, which promotes awareness and can prevent accidents.

When making a turn, signaling informs others that you are shifting your vehicle's direction and prepares them to adjust accordingly. Similarly, when changing lanes, using a signal notifies surrounding vehicles of your intention to move into another lane, allowing them to provide space or prepare for your maneuver.

In the context of driving safety, signaling during these actions helps create a more predictable driving environment, which is crucial for both individual and collective safety on the road. Understanding the importance of signaling in these scenarios reinforces responsible driving habits and adherence to traffic laws.
