What should you do before backing up your vehicle?

The correct choice emphasizes the importance of checking your surroundings before backing up your vehicle. Conducting a 360-degree vision check allows you to assess the area around your vehicle, ensuring that there are no obstacles, pedestrians, or other vehicles that could pose a danger. Checking your mirrors helps to provide additional visibility of areas that may be difficult to see directly from the driver's seat. Together, these actions enhance safety by making sure you have a complete understanding of your surroundings before you engage in reversing your vehicle.

Other actions, such as accelerating quickly or turning on hazard lights, do not address the immediate need for situational awareness when preparing to back up. Additionally, engaging the parking brake is generally not a necessary step before backing up; it is typically used when the vehicle is parked to prevent rolling.
