When backing up should driver turns on the hazard lights?

Drivers should turn on their hazard lights when backing up if they are in a situation that may pose a hazard to other road users, such as backing out of a parking space in a busy area or when visibility is limited. This alerts other drivers and pedestrians of the vehicle's movements, enhancing safety. However, it’s important to ensure that the hazard lights are used appropriately and not as a substitute for proper signaling, such as using turn signals when necessary.
