If you hit a company vehicle and cannot find the owner, the best course of action is to:
Leave a note with your name, address, and registration number in a clearly visible place on the vehicle, and report the crash to the proper law enforcement agency.
This ensures that you are taking responsibility for the accident and following legal requirements. Leaving a note provides a way for the owner to contact you, and reporting the incident helps document the event for insurance purposes. Remember to check local laws, as they may vary by jurisdiction regarding how to handle such situations.
