When is it mandatory to notify the authorities regarding a vehicle accident?

It is mandatory to notify the authorities regarding a vehicle accident in all circumstances to ensure proper documentation and response to the incident. This requirement is in place because accidents can have various implications, including injuries that may not be immediately visible, property damage, and potential legal liability issues. By notifying the authorities, you allow for an official report to be created, which can be essential for insurance claims and determining liability.

The other options suggest conditions under which notification might be required, but do not fully encompass the necessity of reporting every accident. For instance, the presence of visible injuries, parked vehicles, or collisions with other cars may seem like key factors, but they do not capture the complete scope of responsibilities following an accident. It is always prudent and legally necessary to report an accident regardless of circumstances.
