Before engaging in reverse, what should the driver do according to professional backing techniques?

Using the horn and flashers before reversing is essential for ensuring safety during this maneuver. By using the horn, the driver can alert nearby pedestrians and vehicles of their intentions, reducing the risk of accidents. Flashers can also serve to signal to others that the vehicle is about to reverse, enhancing visibility and awareness in the surrounding environment. This practice is particularly important in crowded or poorly lit areas where danger might not be immediately visible.

In contrast, while checking blind spots is critical, it may not be enough on its own without communicating intentions to others nearby. Signaling left and right could be useful, but it may not effectively notify pedestrians or other vehicles in the immediate vicinity. Following a checklist is a disciplined approach, but the specific actions of using the horn and flashers are more immediate responses necessary for safety before backing up.
