Yes, you are generally required by law and safety standards to perform a "head check" or look over your shoulder when reversing, even if your car is equipped with a rearview camera. In many regions, including most U.S. states and Australia, relying solely on mirrors or cameras during a driving test can result in an automatic failure. Physical head checks are necessary because cameras and mirrors have blind spots—areas directly beside or behind the vehicle that technology might miss, such as a small child or a pet moving quickly. The correct technique typically involves placing your right hand behind the passenger headrest (for left-hand drive cars), twisting your torso, and looking directly through the rear window while intermittently checking your side mirrors. This provides the most comprehensive field of vision and ensures you are fully aware of your surroundings before and during the maneuver.
