What is a critical step before reversing a vehicle?

Checking behind the car directly is an essential step before reversing a vehicle because it allows the driver to gain a full view of the area immediately behind the vehicle. This action helps identify any obstacles, pedestrians, or other vehicles that may be in the way, which might not be visible in mirrors alone. While side mirrors can provide some visibility, they do not necessarily show the entire picture behind the vehicle. Looking directly behind ensures that drivers are aware of their surroundings and can make safer reversing decisions.

Additionally, simply looking over the headrest or depending on the vehicle type may not provide adequate safety awareness, as these methods might not cover all blind spots. Prioritizing a direct look behind reinforces safe driving practices and reduces the risk of accidents.
