  Explanation:

  "Turn signals are your primary communication tool, letting others know your intentions. Even if no vehicles are visible, always signal well in advance before turning, changing lanes, or pulling over. However, avoid signaling too early in areas with multiple driveways or lanes, as it may confuse other road users."
