The correct answer is: Do not relieve the driver of responsibility when backing

The function of back-up alarm devices is primarily to alert those nearby that a vehicle is reversing. While the device plays an essential safety role by warning pedestrians and other vehicles of the impending movement, it does not take away the driver's obligations and responsibilities. The driver must remain vigilant and ensure that they check their surroundings through mirrors and direct observation before and during the backing process. In this context, it's important to understand that reliance solely on the alarm can create a false sense of security, potentially leading to accidents if the driver is not paying full attention. Therefore, while the alarm serves as a helpful warning tool, the driver must still exercise caution and responsibility while maneuvering the vehicle in reverse.
