Before reversing their vehicle, which observation should a driver make?

Before reversing a vehicle, it is essential for a driver to look over both shoulders and behind. This action is crucial because it provides a complete view of the area directly behind the vehicle, which is otherwise blocked from view. Relying solely on mirrors, such as the rearview and side mirrors, may not adequately reveal pedestrians, obstacles, or oncoming traffic that could be present in the blind spots. By physically turning their head and looking, drivers can ensure they are aware of their surroundings, reducing the risk of accidents when backing up. This practice emphasizes the importance of active observation over passive methods, ensuring safety for all road users.
