What should you do when backing up your vehicle?

Answer: C — Place your arm on the back of the seat and look directly through the rearview window

When backing up your vehicle, placing your arm on the back of the seat and looking directly through the rear window is the safest practice. This method allows the driver to maintain full visibility of the area behind the vehicle. Turning the body helps to give a broader view of the surroundings, ensuring that you can see pedestrians, other vehicles, or obstacles that may not be visible through the mirrors alone. Using only the rearview mirror does not provide a comprehensive view, as it is limited in coverage and may miss blind spots or lower objects. Likewise, relying on a parking assist screen is not enough, as it can fail to detect objects that are outside the camera's range or may have a delay in displaying real-time images. Therefore, the technique of turning your body and looking out of the rear window significantly enhances safety while reversing.
