When must you use your turn signals while driving?

Answer: B — Whenever you plan to turn or change lanes

Using turn signals is an essential aspect of safe driving and effective communication with other road users. The correct answer emphasizes that you must signal whenever you plan to turn or change lanes. This practice alerts other drivers, cyclists, and pedestrians of your intentions, helping to prevent accidents and misunderstandings on the road. In many traffic laws, signaling is not restricted to specific situations but applies broadly to any action that alters your path of travel. For instance, when changing lanes, it’s crucial to indicate your intention well in advance, allowing those around you to respond appropriately. Similarly, signaling before turning informs other drivers who may not easily see your maneuvers. Using signals underlines a driver's responsibility to keep the road environment predictable and safe, which is why it is important to make signaling a habit regardless of traffic conditions or the proximity of other vehicles.
