When must you signal by hand and arm or a signal device?

Answer: (C)

Signaling by hand and arm or using a signal device is essential for safely changing lanes. Whenever a driver intends to change lanes, it is crucial to communicate that intention to other road users, which helps prevent accidents. This requirement applies regardless of the time of day or the specific type of area a driver is traveling through, including residential areas or at intersections. Signaling serves as a warning to other drivers that you are about to make a maneuver, allowing them to respond appropriately, thus enhancing overall road safety.
