If you are preparing to reverse, what should your first action be?

The first action you should take when preparing to reverse is to check for any obstacles outside the vehicle. This is crucial because reversing can often lead to accidents if you're unaware of your surroundings. Before engaging the reverse gear, a driver must ensure that the area behind the vehicle is clear of pedestrians, other vehicles, and any potential hazards. By taking this step first, you significantly reduce the risk of collisions and ensure a safer maneuver.

Engaging the reverse gear immediately without assessing the surroundings could lead to dangerous situations. Simply checking the rearview mirror does not provide a complete picture of what is behind you, as mirrors can have blind spots. While sounding your horn could alert others to your presence, it does not address the importance of actively ensuring the path is clear before movement. Thus, being proactive in checking for obstacles is the safest and most responsible first action to take.
