What does signaling backward indicate to other road users?

Signaling backward is primarily used to communicate to other road users that the vehicle intends to reverse. This is critical for safety, as it alerts pedestrians and other drivers that the vehicle is about to move in the opposite direction, allowing them to take appropriate precautions or give space. Clear communication through signaling helps prevent accidents by ensuring everyone on the road is aware of a vehicle's intentions.

The other options may relate to vehicle movements, but they do not accurately describe the action associated with signaling backward. For instance, signaling to stop or to turn left does not convey the intention to reverse. Instead, those actions typically involve different signals that specifically indicate stopping or turning. Therefore, signaling backward effectively conveys the intention to reverse, thereby promoting safety on the road.
