When is it necessary to use turn signals while driving?

Answer: C — Before making any turns or lane changes

Using turn signals is crucial for ensuring safety and effective communication on the road. It's necessary to signal before making any turns or lane changes because this allows other drivers and pedestrians to anticipate your actions, which helps prevent accidents. Turn signals provide a clear indication of your intentions, allowing those around you to respond accordingly. In busy traffic situations, or even in less congested areas, signaling can be the difference between maintaining a safe flow of traffic and causing confusion, which may lead to dangerous situations. Proper use of turn signals is a fundamental driving practice that helps to inform other road users of your next move, promoting a safer driving environment.
